Description

[Technical Field]

[0001] The present invention relates to a clamp for fixing, to a predetermined location, an electric wire passing through a position spaced from the predetermined location, and a clamp-equipped wire harness. [Background technology]

[0002] In vehicles such as automobiles, electric wires and wire harnesses are fixed to predetermined locations on the vehicle body using clamps, thereby restricting their routing. In this case, the electric wires and wire harnesses are sometimes routed so as to pass through locations spaced apart from the predetermined locations.

[0003] In such cases, the clamp must be composed of a fixing part that is fixed to a predetermined location and a clamp body that extends from the fixing part and has an electric wire fixed to its tip, and the length of the clamp body must be set to a length that corresponds to the distance between the predetermined location and the electric wire.

[0004] However, when the distance between the predetermined point and the electric wire varies for each predetermined point, different clamps must be used depending on the distance between the predetermined point and the electric wire, which results in an increase in the number of clamp types.To address this issue, a clamp has been proposed in which the length of the clamp body can be changed to match the distance between the predetermined point and the electric wire.

[0005] For example, the clamp in Patent Document 1 is composed of a fixed portion (engaged portion) that is fixed at a predetermined location, a clamp body that extends from the fixed portion in a predetermined direction, and a harness clamp portion that extends from the side of the clamp body and to which the wire harness is fixed.

[0006] Furthermore, the clamp of Patent Document 1 has a clamp body that is composed of multiple protruding plate portions connected in a predetermined direction via hinge portions and one base portion, and a fixing portion is provided on the protruding plate portion located at one end side in the predetermined direction, and a harness clamp portion is provided on the base portion.

[0007] The clamp of Patent Document 1 allows the length of the clamp body to be changed to a length that corresponds to the distance between a specified point and the electric wire by folding the protruding plate portions at the hinge portion so that adjacent protruding plate portions overlap each other across the hinge portion. At this time, the clamp of Patent Document 1 maintains the deformed state of the clamp body by fitting a protrusion provided on one of the protruding plate portions into a through-hole provided on the other protruding plate portion.

[0008] However, in Patent Document 1, since the wire harness is not fixed to the clamp body, when the wire harness sways due to vibrations during driving, for example, the projections and recesses may be disengaged from each other, and the state in which the wiring route of the wire harness is regulated may not be stably maintained. Therefore, Patent Document 1 has room for improvement in terms of maintaining the state in which the wiring route of the electric wires is regulated. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 2019-140846 Summary of the Invention [Problem to be solved by the invention]

[0010] In view of the above-mentioned problems, the present invention aims to provide a clamp and a wire harness with a clamp that can change the length of the clamp body to a length corresponding to the distance between a predetermined point and an electric wire, and can stably maintain a state in which the routing path of the electric wire is restricted. [Means for solving the problem]

[0011] The present invention relates to a clamp having a fixing portion that is fixed to a predetermined location, and that fixes at least one electric wire passing through a position spaced apart from the predetermined location in a predetermined direction, to the predetermined location, the clamp comprising a substantially band-shaped clamp body having a plurality of insertion holes that are opened at intervals in the predetermined direction and through which a bundling member that is wound around the electric wire is inserted, the clamp body comprising a plate-shaped first body portion that extends from the fixing portion in the predetermined direction, a second body portion that is adjacent to the first body portion in the predetermined direction, and a bent-back portion that connects the second body portion to the first body portion in a state that the second body portion can be bent back in a direction opposite to the predetermined direction, and the second body portion is fixed to the first body portion together with the electric wire by the bundling member. the clamp body is provided with a plurality of hinge portions that pivotally connect locations adjacent to the insertion holes, the bent-back portion is configured as one of the plurality of hinge portions, the clamp body on the predetermined direction side of the hinge portion that becomes the bent-back portion is configured as the second body portion, the second body portion is folded back by the bent-back portion and overlaps the first body portion, and in a state where the second body portion overlaps the first body portion, the two insertion holes of the second body portion adjacent to the bent-back portion communicate with the two insertion holes of the first body portion. It is characterized by:

[0012] The present invention is also characterized in that it provides a clamp-equipped wire harness including the above-mentioned clamp, a wire harness bundling a plurality of electric wires, and a bundling member for bundling the wire harness to the clamp. The term "bending back" as used herein refers to bending back by rotating to one side in a direction perpendicular to the main surface of the protector body, or bending back by curving toward one side in the perpendicular direction.

[0013] The hinge portion may be, for example, a hinge portion formed by thinning a portion of the clamp body, or a hinge portion composed of a shaft and a shaft tube.Furthermore, the hinge portion may be one provided between two insertion holes adjacent in a predetermined direction, or one provided between a set of adjacent insertion holes, where a plurality of insertion holes adjacent in a predetermined direction are considered as one set of insertion holes.

[0014] According to this invention, the clamp and the clamp-equipped wire harness can change the length of the clamp body to a length corresponding to the distance between a predetermined location and the electric wire, and can stably maintain a state in which the routing path of the electric wire is restricted.

[0015] Specifically, since the first body portion and the second body portion are connected via the bent portion, when the second body portion is bent back to a position corresponding to the distance between the specified point in the specified direction and the electric wire, the length of the clamp body in the specified direction, including the bent portion, can be changed to a length corresponding to the distance between the specified point in the specified direction and the electric wire.

[0016] For example, by making one of the multiple hinge portions provided on the clamp body, which corresponds to the distance between a specified location and the electric wire, a bent-back portion, the length of the clamp body including the bent-back portion can be changed to a length corresponding to the distance between the specified location and the electric wire.

[0017] Alternatively, by using a flexible band-shaped body as the bent-back portion and setting the bent-back position of the bent-back portion to a position corresponding to the distance between the specified location and the electric wire, the length of the clamp body including the bent-back portion can be changed to a length corresponding to the distance between the specified location and the electric wire.

[0018] Therefore, when the electric wire is fixed to the clamp body, the clamp can reduce the length of the excess length that occurs on the predetermined direction side of the electric wire compared to when the electric wire is fixed to a clamp body that is extremely long in the predetermined direction relative to the distance between the predetermined point and the electric wire, thereby preventing interference between the clamp body and members or devices provided around the electric wire.

[0019] Furthermore, since the electric wires and the second main body part are fixed to the first main body part by the binding member, even if the electric wires sway due to vibrations during driving, for example, the electric wires and the second main body part will not come off the first main body part.

[0020] Therefore, the clamp and the clamp-equipped wire harness can change the length of the clamp body to a length that corresponds to the distance between the specified location and the electric wire, and can stably maintain a state in which the routing path of the electric wire is restricted.

[0021] In addition, since the length of the clamp body can be changed to a length that corresponds to the distance between the specified location and the electric wire, the clamp and the clamp-equipped wire harness can be made standardized, eliminating the need to use different clamps depending on the distance between the specified location and the electric wire.

[0022] Also,The clamp body is provided with a plurality of hinge portions that pivotally connect locations adjacent to the insertion holes, the bent-back portion is configured by one of the plurality of hinge portions, the clamp body on the predetermined direction side of the hinge portion that becomes the bent-back portion is configured as the second body portion, the second body portion is folded back by the bent-back portion and overlaps the first body portion, and in a state where the second body portion overlaps the first body portion, the two insertion holes of the second body portion adjacent to the bent-back portion communicate with the two insertion holes of the first body portion. is.

[0023] According to this configuration, by providing multiple hinge portions, the clamp can change the length of the clamp body with a simpler configuration than, for example, changing the length of the clamp body by rearranging multiple plate materials.

[0024] Furthermore, because the two insertion holes of the second body portion communicate with the two insertion holes of the first body portion, the clamp allows the binding member to be inserted into one of the communicating insertion holes and the other communicating insertion hole, thereby enabling the clamp to easily and reliably fix the second body portion and the electric wires to the first body portion via the binding member.

[0025] child As an aspect of the invention, the multiple hinge portions may include two first hinge portions formed on either side of two adjacent insertion holes in the specified direction, and a second hinge portion formed approximately in the center between the first hinge portions. According to this configuration, the second hinge portion located between the first hinge portions allows the length of the clamp body of the clamp to be changed to a length that is more suitable for the distance between the predetermined location and the electric wire.

[0026] Furthermore, when the second body portion is bent back using the second hinge portion as a bending portion, the first hinge portions overlap. In this case, the electric wires and the binding member are attached so as to straddle the first hinge portion, so the clamp can prevent deformation of the clamp body with the first hinge portion as a fulcrum. Therefore, even when the clamp is provided with the second hinge portion, it can stably maintain a state in which the routing path of the electric wires is restricted.

[0027] In another aspect of the present invention, the hinge portion closest to the fixed portion among the plurality of hinge portions may be formed at a position where the length of the first main body portion in the specified direction is approximately the same as the length of the second main body portion in the specified direction.

[0028] With this configuration, when the second main body portion is bent back at the hinge portion closest to the fixed portion, the tip of the bent back second main body portion will approximately coincide with the end of the first main body portion on the side opposite to the specified direction.

[0029] This prevents the bent second main body portion from protruding from the first main body portion in the opposite direction to the specified direction, thereby preventing interference between the clamp main body and components or equipment located around the specified location.

[0030] In another aspect of the present invention, either one of the overlapping first main body portion and second main body portion may be provided with a locking portion that protrudes from one toward the other and is locked to the other.

[0031] According to this configuration, the overlapping first and second body parts are connected by the locking portion, so that when, for example, fixing an electric wire to the clamp body, the worker does not have to take the trouble of grasping the first and second body parts and maintaining the overlapping state of the first and second body parts. This allows the clamp to easily insert the bundling member into the insertion hole, improving the ease of bundling work when fixing the electric wires.

[0032] In another aspect of the present invention, the locking portions may be provided on the first main body portion and the second main body portion, respectively, and when the first main body portion and the second main body portion are overlapped, the locking portions of the first main body portion and the locking portions of the second main body portion may be arranged alternately along the specified direction.

[0033] With this configuration, the locking portions of the first body part and the second body part are arranged alternately along a predetermined direction, so that when the clamp body bends back the second body part at the bending portion, there is no interference between the locking portions of the first body part and the second body part. This allows the clamp to reliably overlap the second body portion on the first body portion, further improving the ease of binding the binding member.

[0034] In another aspect of the present invention, the locking portion may be provided upright on a main surface of the clamp body and locked in the insertion hole. With this configuration, the clamp can prevent the clamp body from becoming larger in size in a direction parallel to the main surface of the clamp body and perpendicular to the specified direction, compared to, for example, a case in which a locking portion is provided on the side of the clamp body in a direction parallel to the main surface of the clamp body and perpendicular to the specified direction.

[0035] Furthermore, because the locking portions are locked into the insertion holes, the clamp can effectively utilize the multiple insertion holes provided in the clamp body not only as openings through which the binding members are inserted but also as openings through which the locking portions are locked, thereby preventing a decrease in the rigidity of the clamp body compared to when a clamp has separate openings through which the locking portions are locked.

[0036] In another aspect of the present invention, the clamp body may be provided with a pair of side wall portions that are erected opposite each other in a direction parallel to the main surface of the clamp body and perpendicular to the specified direction, and the side wall portions may be provided with a separation portion that is separated from the hinge portion at a position in the specified direction that is approximately the same as the hinge portion. The above-mentioned separation portion refers to a portion that has been thinned to facilitate separation, or a portion that has been cut to facilitate separation.

[0037] According to this configuration, the rigidity of the first body portion and the rigidity of the second body portion can be improved by the pair of side walls, so that the clamp can reliably ensure the supporting rigidity of the electric wire. Furthermore, since the side wall portion can be separated at a position in approximately the same predetermined direction as the hinge portion, the clamp body can be easily bent back at the bent-back portion even when a pair of side wall portions is provided.

[0038] In another aspect of the present invention, the clamp body may be configured to include a central portion extending in the specified direction in which the insertion hole is provided, and both end portions connected to the edge of the central portion in a state in which they can be bent toward the main surface of the central portion, parallel to the main surface of the central portion and perpendicular to the specified direction, and the both end portions of the first main body portion may be configured to abut against the end surfaces of the second main body portion in the specified direction when bent toward the main surface of the central portion.

[0039] With this configuration, both end portions of the first body portion overlap with the central portion of the first body portion, and the clamp can prevent deformation of the central portion of the first body portion that does not overlap with the second body portion by both end portions of the first body portion.

[0040] Furthermore, the clamp can prevent deformation of the first body at the end face of the second body by abutting both end portions of the first body with the end faces of the second body, thereby ensuring the clamp's support rigidity for the electric wire. [Effects of the Invention]

[0041] The present invention makes it possible to provide a clamp and a wire harness with a clamp that can change the length of the clamp body to a length corresponding to the distance between a predetermined location and an electric wire, and can stably maintain a state in which the routing path of the electric wire is restricted.

Furthermore, FIG. 4 shows a cross-sectional view of the clamp 10 taken along the line AA in the deployed state.

[0048] 1 is the top of the clamp-equipped wire harness 1, the bottom of FIG. 1 is the bottom of the clamp-equipped wire harness 1, the arrow X in the figure indicates the front-to-rear direction (hereinafter referred to as the front-to-rear direction X), and the arrow Y in the figure indicates the width direction (hereinafter referred to as the width direction Y).

[0049] As shown in FIG. 1, the clamp-equipped wire harness 1 of Example 1 includes a wire harness WH arranged with its longitudinal direction substantially aligned with the front-to-rear direction X, a cable tie 2 wrapped around the wire harness WH, and a clamp 10 to which the wire harness WH is attached via the cable tie 2 at an end on one side in the width direction Y.

[0050] The wire harness WH is configured by bundling together a plurality of electric wires (not shown) that electrically connect, for example, a power source and electrical devices of a vehicle. As shown in Fig. 2(a), the wire harness WH is routed so as to pass through an anchor fixing portion 3a, which is an opening provided in a body 3 of the vehicle, at a position spaced a predetermined distance to one side in the width direction Y. The anchor fixing portion 3a is a through-hole provided in the plate-shaped vehicle body 3 having a thickness in the vertical direction, and is formed to have a generally oblong shape that is long in the width direction Y when viewed from above.

[0051] 1, the cable tie 2 is a binding member that binds the wire harness WH to the clamp 10. As shown in FIGS. 1 and 2(a), the cable tie 2 is composed of a substantially belt-shaped band portion 2a and a lock portion 2b that is provided at one end of the band portion 2a and that locks the other end of the band portion 2a.

[0052] 1 and 2, the clamp 10 is a member that fixes the wire harness WH, which passes through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y, to the anchor fixing portion 3a of the vehicle body 3.

[0053] As shown in Figures 1 to 4, this clamp 10 is composed of an anchor portion 11 that engages with the anchor fixing portion 3a, and a roughly belt-shaped clamp body 13 that extends from the anchor portion 11 to one side in the width direction Y and has six insertion holes 12, through which the cable ties 2 are inserted, opened at predetermined intervals in the width direction Y.

[0054] Specifically, as shown in Fig. 4, the anchor portion 11 of the clamp 10 is composed of a shaft 11a that is elongated in the width direction Y and has a generally oblong shape in plan view, and a pair of locking claws 11b that extend from the shaft 11a in the width direction Y. As shown in Fig. 4, the anchor portion 11 is fixed to the vehicle body 3 by inserting the shaft 11a into the anchor fixing portion 3a of the vehicle body 3 and locking the locking claws 11b to the edge of the anchor fixing portion 3a.

[0055] On the other hand, as shown in Figures 1 and 2, the clamp body 13 of the clamp 10 is configured to be bendable to the other side in the width direction Y, and includes a plate-shaped first body portion 131 extending from the anchor portion 11 to one side in the width direction Y, a second body portion 132 adjacent to the first body portion 131 on one side in the width direction Y, and a bending portion 133 connecting the second body portion 132 to the first body portion 131 in a state in which it can be bent to the other side in the width direction Y.

[0056] As shown in Figures 3 and 4, when the bent second main body portion 132 is unfolded, the clamp main body 13 has a predetermined thickness in the vertical direction and is formed into a roughly rectangular plate shape in plan view that is long in the width direction Y.

[0057] Specifically, as shown in Figures 3 and 4, the clamp body 13 in the unfolded state is composed of three hinge portions 14 that enable bending to the other side in the width direction Y at positions spaced a predetermined distance apart in the width direction Y, and four flat plate portions 15 connected by the hinge portions 14.

[0058] The three hinge portions 14 are formed so as to be able to bend back to the other side in the width direction Y while rotating the second main body portion 132 downward. Specifically, as shown in Fig. 4, the three hinge portions 14 are formed by thinning the upper surface side of the clamp main body 13 so as to have a generally V-shaped groove shape in a front view that tapers downward and extends in the front-rear direction X.

[0059] As shown in Figure 2, this type of clamp 10 has one of the three hinge portions 14 as a bent-back portion 133, and the second main body portion 132 on one side of the bent-back portion 133 in the width direction Y is bent back to the other side in the width direction Y, thereby making it possible to change the length in the width direction Y.

[0060] As shown in Figure 2, the clamp 10 fixes the bent-back second main body portion 132 together with the wire harness WH using a cable tie 2 to the first main body portion 131 on the other side in the width direction Y than the bent-back portion 133, thereby fixing the wire harness WH, which passes through a position spaced apart from the anchor fixing portion 3a, to the vehicle body 3.

[0061] Here, to facilitate the following explanation, the end face on one side of the clamp body 13 in the width direction Y will be referred to as the harness side end face, and the end face on the other side of the clamp body 13 in the width direction Y will be referred to as the vehicle body side end face.

[0062] Furthermore, the clamp body 13 will be described in detail below, with the five boundary positions (positions of the dotted lines in Figure 4) when the space between the harness side end face and the vehicle body side end face is divided into six equal parts, being designated as the first boundary position P1, the second boundary position P2, the third boundary position P3, the fourth boundary position P4, and the fifth boundary position P5, in that order from the vehicle body side end face toward one side in the width direction Y.

[0063] More specifically, of the three hinge portions 14, the first hinge portion 14 is composed of a first hinge portion 14a that is provided at approximately the same position as the third boundary position P3 in the width direction Y, as shown in FIG. 4.

[0064] Furthermore, of the three hinge portions 14, the second and third hinge portions 14 are composed of a second hinge portion 14b located approximately in the center between the third boundary position P3 and the fourth boundary position P4, and a third hinge portion 14c located at approximately the same position as the fourth boundary position P4, as shown in Figure 4.

[0065] Furthermore, of the four flat plate portions 15, the first and second flat plate portions 15 are composed of a first flat plate portion 15a on the other side of the first hinge portion 14a in the width direction Y, and a second flat plate portion 15b between the first hinge portion 14a and the second hinge portion 14b, as shown in Figures 3 and 4.

[0066] Furthermore, of the four flat plate portions 15, the third and fourth flat plate portions 15 are composed of a third flat plate portion 15c between the second hinge portion 14b and the third hinge portion 14c, and a fourth flat plate portion 15d on one side of the third hinge portion 14c in the width direction Y, as shown in Figures 3 and 4.

[0067] As shown in Figures 3 and 4, the first flat plate portion 15a of the clamp body 13 has an anchor portion 11 provided at approximately the center in the width direction Y between the vehicle body side end surface and the first boundary position P1. Furthermore, as shown in Figures 3 and 4, the first flat plate portion 15a has the first insertion hole 12 (hereinafter referred to as the first insertion hole 12a) and the second insertion hole 12 (hereinafter referred to as the second insertion hole 12b) of the six insertion holes 12 mentioned above, counting from the anchor portion 11.

[0068] In addition, as shown in Figures 3 and 4, the second flat plate portion 15b of the clamp body 13 has an opening formed therein that is the third insertion hole 12 (hereinafter referred to as the third insertion hole 12c) of the six insertion holes 12 mentioned above, counting from the anchor portion 11.

[0069] In addition, as shown in Figures 3 and 4, the third flat plate portion 15c of the clamp body 13 has an opening formed therein that is the fourth insertion hole 12 (hereinafter referred to as the fourth insertion hole 12d) of the six insertion holes 12 mentioned above, counting from the anchor portion 11.

[0070] Furthermore, as shown in Figures 3 and 4, the fourth flat plate portion 15d of the clamp body 13 has a fifth insertion hole 12 (hereinafter referred to as the fifth insertion hole 12e) and a sixth insertion hole 12 (hereinafter referred to as the sixth insertion hole 12f) of the six insertion holes 12 mentioned above, counting from the anchor portion 11.

[0071] As shown in FIG. 3, the six insertion holes 12 are openings that are generally rectangular in plan view and are long in the front-rear direction X, and are formed at equal intervals in the width direction Y. Furthermore, the six insertion holes 12 are formed so that when any one of the three hinge portions 14 is used as a bent-back portion 133 and the clamp body 13 is bent back, four or more adjacent to the bent-back portion 133 are connected to form two or more through holes.

[0072] More specifically, as shown in FIG. 4, the first insertion hole 12a and the second insertion hole 12b are formed to open at positions that are line-symmetrical about the center between the second boundary position P2 and the third boundary position P3. As shown in Figure 4, the third insertion hole 12c is formed at a position that is linearly symmetrical to the second insertion hole 12b at the third boundary position P3 so that it communicates with the second insertion hole 12b when the clamp body 13 is bent back at the first hinge portion 14a.

[0073] As shown in Figure 4, the fourth insertion hole 12d is formed at a position that is linearly symmetrical to the third insertion hole 12c in the center between the third boundary position P3 and the fourth boundary position P4 so that it communicates with the third insertion hole 12c when the clamp body 13 is bent back at the second hinge portion 14b, for example.

[0074] As shown in Figure 4, the fifth insertion hole 12e is formed at a position that is linearly symmetrical to the fourth insertion hole 12d at the fourth boundary position P4 so that it communicates with the fourth insertion hole 12d when the clamp body 13 is bent back at the third hinge portion 14c, for example.

[0075] As shown in Figure 4, the sixth insertion hole 12f is formed at a position that is linearly symmetrical to the fifth insertion hole 12e in the center between the fourth boundary position P4 and the fifth boundary position P5 so as to communicate with the third insertion hole 12c when the clamp body 13 is bent back at the third hinge portion 14c, for example.

[0076] Next, a state of the clamp 10 in which the length in the width direction Y is changed by using any one of the first hinge portion 14a, the second hinge portion 14b, and the third hinge portion 14c as the bent-back portion 133 will be described.

[0077] First, when the third hinge portion 14c is the bent-back portion 133, the first main body portion 131 of the clamp 10 is composed of a first flat plate portion 15a, a first hinge portion 14a, a second flat plate portion 15b, a second hinge portion 14b, and a third flat plate portion 15c, as shown in FIG. 2(a). On the other hand, the second main body portion 132 of the clamp 10 is formed of a fourth flat plate portion 15d, as shown in FIG. 2(a).

[0078] In this case, as shown in Figure 2(a), when the second main body portion 132 overlaps the first main body portion 131, the two insertion holes 12 of the second main body portion 132 adjacent to the bent-back portion 133 and the two insertion holes 12 of the first main body portion 131 adjacent to the bent-back portion 133 are connected in the vertical direction.

[0079] Specifically, in the clamp 10, the fifth insertion hole 12e of the second main body portion 132 communicates with the fourth insertion hole 12d of the first main body portion 131, and the sixth insertion hole 12f of the second main body portion 132 communicates with the third insertion hole 12c of the first main body portion 131. Note that the lower openings of the first insertion hole 12a and the second insertion hole 12b of the first main body portion 131 are closed by the fourth flat plate portion 15d of the second main body portion 132.

[0080] With respect to the clamp 10 whose length in the width direction Y is changed in this manner, the wire harness WH is disposed between the fifth insertion hole 12e and the sixth insertion hole 12f, as shown in Fig. 2(a). Furthermore, the binding band 2 is inserted through the fourth insertion hole 12d and the fifth insertion hole 12e, which are connected to each other, and through the third insertion hole 12c and the sixth insertion hole 12f, which are connected to each other, as shown in Fig. 2(b).

[0081] The band portion 2a of the binding band 2 is wound around the wire harness WH and is locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which the wire harness WH is attached to the clamp 10.

[0082] At this time, the second main body portion 132 overlaps the first hinge portion 14a and the second hinge portion 14b, and the clamp 10 uses the second main body portion 132 to restrict deformation of the clamp main body 13 with the first hinge portion 14a or the second hinge portion 14b as a fulcrum.

[0083] Furthermore, when the second hinge portion 14b is configured as the bent-back portion 133, the first main body portion 131 of the clamp 10 is composed of a first flat plate portion 15a, the first hinge portion 14a, and a second flat plate portion 15b, as shown in Figure 2(b). On the other hand, as shown in FIG. 2(b), the second main body portion 132 of the clamp 10 is made up of a third flat plate portion 15c, a third hinge portion 14c, and a fourth flat plate portion 15d.

[0084] In this case, as shown in Figure 2(b), when the second main body portion 132 overlaps the first main body portion 131, the three insertion holes 12 of the second main body portion 132 adjacent to the bent-back portion 133 and the three insertion holes 12 of the first main body portion 131 adjacent to the bent-back portion 133 are connected in the vertical direction.

[0085] Specifically, in the clamp 10, the fourth insertion hole 12d of the second main body portion 132 is connected to the third insertion hole 12c of the first main body portion 131, the fifth insertion hole 12e of the second main body portion 132 is connected to the second insertion hole 12b of the first main body portion 131, and the sixth insertion hole 12f of the second main body portion 132 is connected to the first insertion hole 12a of the first main body portion 131.

[0086] With respect to the clamp 10 whose length in the width direction Y has been changed in this way, the wire harness WH is disposed between the fourth insertion hole 12d and the fifth insertion hole 12e, as shown in Fig. 2(b). Furthermore, as shown in Fig. 2(b), the binding band 2 is inserted through the second insertion hole 12b and the fifth insertion hole 12e, which are connected to each other, and the third insertion hole 12c and the fourth insertion hole 12d, which are connected to each other.

[0087] The band portion 2a of the binding band 2 is wound around the wire harness WH and is locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which the wire harness WH is attached to the clamp 10.

[0088] At this time, the first hinge portion 14a and the third hinge portion 14c overlap with each other, so that the other hinge portion of the clamp 10 restricts deformation of the clamp body 13 with the first hinge portion 14a or the third hinge portion 14c as the fulcrum.

[0089] Furthermore, when the first hinge portion 14a is configured as the bent-back portion 133, the first main body portion 131 of the clamp 10 is configured as a first flat plate portion 15a, as shown in FIG. 2(c). On the other hand, as shown in FIG. 2(c), the second main body portion 132 of the clamp 10 is composed of a second flat plate portion 15b, a second hinge portion 14b, a third flat plate portion 15c, a third hinge portion 14c, and a fourth flat plate portion 15d.

[0090] In this case, as shown in Figure 2(c), when the second main body portion 132 overlaps the first main body portion 131, the clamp 10 overlaps so that the end face of the second main body portion 132 on the other side of the width direction Y is positioned at approximately the same position as the end face of the first main body portion 131 on the other side of the width direction Y.

[0091] Furthermore, as shown in Figure 2(c), when the second main body portion 132 overlaps the first main body portion 131, the two insertion holes 12 of the second main body portion 132 adjacent to the bent-back portion 133 and the two insertion holes 12 of the first main body portion 131 adjacent to the bent-back portion 133 are connected in the vertical direction.

[0092] Specifically, in the clamp 10, the third insertion hole 12c of the second body portion 132 communicates with the second insertion hole 12b of the first body portion 131, and the fourth insertion hole 12d of the second body portion 132 communicates with the first insertion hole 12a of the first body portion 131. Note that the upper openings of the fifth insertion hole 12e and the sixth insertion hole 12f of the second body portion 132 are closed by the first body portion 131.

[0093] With respect to the clamp 10 whose length in the width direction Y has been changed in this way, the wire harness WH is disposed between the third insertion hole 12c and the fourth insertion hole 12d, as shown in Fig. 2(c). Furthermore, as shown in Fig. 2(c), the binding band 2 is inserted through the second insertion hole 12b and the third insertion hole 12c, which are connected to each other, and the first insertion hole 12a and the fourth insertion hole 12d, which are connected to each other.

[0094] The band portion 2a of the binding band 2 is wound around the wire harness WH and is locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which the wire harness WH is attached to the clamp 10.

[0095] At this time, the second hinge portion 14b and the third hinge portion 14c of the second main body portion 132 overlap with the first main body portion 131, and the clamp 10 uses the first main body portion 131 to restrict deformation of the clamp main body 13 with the second hinge portion 14b or the third hinge portion 14c as the fulcrum.

[0096] As described above, the clamp 10 of Example 1 has an anchor portion 11 fixed to the anchor fixing portion 3a, and fixes the wire harness WH passing through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y to the anchor fixing portion 3a.

[0097] Furthermore, the clamp 10 is provided with a generally band-shaped clamp body 13 having a plurality of insertion holes 12 opened at intervals on one side in the width direction Y, through which the cable ties 2 to be wrapped around the wire harness WH are inserted.

[0098] This clamp body 13 is configured to include a plate-shaped first body portion 131 extending from the anchor portion 11 to one side in the width direction Y, a second body portion 132 adjacent to the first body portion 131 on one side in the width direction Y, and a bent-back portion 133 that connects the second body portion 132 to the first body portion 131 in a state that allows it to be bent back to the other side in the width direction Y. The second main body portion 132 is fixed to the first main body portion 131 together with the wire harness WH by the binding band 2.

[0099] The clamp-equipped wire harness 1 of the first embodiment described above includes the clamp 10, a wire harness WH in which a plurality of electric wires are bundled together, and a binding band 2 that ties the wire harness WH to the clamp 10.

[0100] According to this configuration, the clamp 10 and the clamp-equipped wire harness 1 can change the length of the clamp body 13 to a length corresponding to the distance between the anchor fixing portion 3a and the wire harness WH, and can stably maintain a state in which the routing path of the wire harness WH is restricted.

[0101] Specifically, since the first main body portion 131 and the second main body portion 132 are connected via the bent-back portion 133, when the second main body portion 132 is bent back to a position corresponding to the distance between the anchor fixing portion 3a and the wire harness WH in the width direction Y, the length of the clamp main body 13 in the width direction Y, including the bent-back portion 133, can be changed to a length corresponding to the distance between the anchor fixing portion 3a and the wire harness WH in the width direction Y.

[0102] More specifically, by making one of the multiple hinge portions 14 provided on the clamp body 13 into a bent-back portion 133, which corresponds to the distance between the anchor fixing portion 3a and the wire harness WH, the clamp 10 can change the length of the clamp body 13 including the bent-back portion 133 to a length that corresponds to the distance between the anchor fixing portion 3a and the wire harness WH.

[0103] Therefore, when the wire harness WH is fixed to the clamp body 13, the clamp 10 can reduce the length of the excess length that occurs on one side of the wire harness WH in the width direction Y, compared to when the wire harness WH is fixed to a clamp body whose length in the width direction Y is extremely long compared to the distance between the anchor fixing portion 3a and the wire harness WH. This allows the clamp 10 to prevent interference between the clamp body 13 and members and devices provided around the wire harness WH.

[0104] Furthermore, since the wire harness WH and the second main body portion 132 are fixed to the first main body portion 131 by the cable tie 2, even if the wire harness WH sways due to vibrations while driving, for example, the wire harness WH and the second main body portion 132 will not detach from the first main body portion 131.

[0105] Therefore, the clamp 10 and the clamp-equipped wire harness 1 can change the length of the clamp body 13 to a length corresponding to the distance between the anchor fixing portion 3a and the wire harness WH, and can stably maintain a state in which the routing path of the wire harness WH is restricted.

[0106] In addition, since the length of the clamp body 13 can be changed to a length corresponding to the distance between the anchor fixing portion 3a and the wire harness WH, the clamp 10 and the clamp-equipped wire harness 1 do not need to be used differently depending on the distance between the anchor fixing portion 3a and the wire harness WH, and the clamp 10 can be used in common.

[0107] In addition, the clamp body 13 is provided with a plurality of hinge portions 14 that pivotally connect the portions adjacent to the insertion holes 12, and the bent-back portion 133 is formed by one of the plurality of hinge portions 14.

[0108] Furthermore, the clamp body 13 is configured such that the clamp body 13 on one side in the width direction Y of the hinge portion 14, which becomes the bent-back portion 133, is the second body portion 132, and the second body portion 132 is folded back by the bent-back portion 133 and overlaps the first body portion 131.

[0109] The clamp 10 is configured such that when the second main body portion 132 overlaps the first main body portion 131, the two insertion holes 12 of the second main body portion 132 adjacent to the bent-back portion 133 communicate with the two insertion holes 12 of the first main body portion 131.

[0110] According to this configuration, by providing multiple hinge portions 14, the clamp 10 can change the length of the clamp body 13 with a simpler configuration than, for example, changing the length of the clamp body by rearranging multiple plate materials.

[0111] Furthermore, because the two insertion holes 12 of the second main body portion 132 communicate with the two insertion holes 12 of the first main body portion 131, the clamp 10 can insert the cable ties 2 into one of the communicating insertion holes 12 and the other of the communicating insertion holes 12. Therefore, the clamp 10 can easily and reliably fix the second main body portion 132 and the wire harness WH to the first main body portion 131 via the cable ties 2.

[0112] The multiple hinge portions 14 include a first hinge portion 14a and a third hinge portion 14c formed on either side of two adjacent insertion holes 12 in the width direction Y, and a second hinge portion 14b formed approximately in the center between the first hinge portion 14a and the third hinge portion 14c. According to this configuration, the second hinge portion 14b located between the first hinge portion 14a and the third hinge portion 14c enables the clamp 10 to change the length of the clamp body 13 to a length that is more suitable for the distance between the anchor fixing portion 3a and the wire harness WH.

[0113] Furthermore, when second main body portion 132 is bent back using second hinge portion 14b as bent-back portion 133, first hinge portion 14a and third hinge portion 14c overlap. In this case, since wire harness WH and cable tie 2 are attached so as to straddle first hinge portion 14a and third hinge portion 14c, clamp 10 can prevent deformation of clamp main body 13 with first hinge portion 14a or third hinge portion 14c as a fulcrum. Therefore, even when second hinge portion 14b is provided, clamp 10 can stably maintain a state in which the routing path of wire harness WH is restricted.

[0114] Furthermore, among the multiple hinge portions 14, the hinge portion 14 (first hinge portion 14a) closest to the anchor portion 11 may be formed at a position where the length of the first main body portion 131 in the width direction Y and the length of the second main body portion 132 in the width direction Y are approximately the same.

[0115] According to this configuration, when the second main body portion 132 is bent back at the hinge portion 14 (first hinge portion 14a) closest to the anchor portion 11, the tip of the bent back second main body portion 132 will approximately coincide with the end portion of the first main body portion 131 on the other side of the width direction Y.

[0116] This prevents the bent second main body portion 132 from protruding from the first main body portion 131 on the other side of the width direction Y of the clamp 10, thereby preventing interference between the clamp main body 13 and components and equipment arranged around the anchor fixing portion 3a. [Example]

[0117] The clamp-equipped wire harness 1 of Example 2 has a different clamp shape from that of Example 1. The clamp-equipped wire harness 1 of Example 2 will be described with reference to Figs.

[0118] 5A and 5B are explanatory diagrams illustrating the appearance of the clamp-equipped wire harness 1 of Example 2, where FIG. 5A shows an external perspective view of the clamp-equipped wire harness 1 as viewed from above and in the front, and FIG. 5B shows an external perspective view of the clamp-equipped wire harness 1 as viewed from below and in the front.

[0119] Furthermore, Figure 6 shows a cross-sectional view taken along the arrow BB in Figure 5, and Figure 7 is an explanatory diagram illustrating the appearance of the clamp 20 in the deployed state, with Figure 7(a) showing an oblique view of the appearance of the clamp 20 as viewed from above and in the front, and Figure 7(b) showing an oblique view of the appearance of the clamp 20 as viewed from below and in the front. Moreover, the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0120] As shown in Figures 5 and 6, the clamp-equipped wire harness 1 of Example 2 includes a wire harness WH that passes through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y, a clamp 20 that fixes the wire harness WH to the anchor fixing portion 3a, and a cable tie 2 that ties the wire harness WH to the clamp 20.

[0121] As shown in Figures 5 to 7, the clamp 20 of Example 2 is composed of an anchor portion 21 that engages with the anchor fixing portion 3a, and a roughly belt-shaped clamp body 23 that extends from the anchor portion 21 to one side in the width direction Y and has eight insertion holes 22, through which the cable ties 2 are inserted, opened at predetermined intervals in the width direction Y. The anchor portion 21 of the clamp 10 has the same configuration as the anchor portion 11 of the clamp 10 in the first embodiment, and therefore a detailed description thereof will be omitted.

[0122] On the other hand, as shown in Figures 5 and 6, the clamp body 23 of the clamp 20 is configured to be able to be bent back to the other side in the width direction Y, and includes a plate-shaped first body portion 231 extending from the anchor portion 21 to one side in the width direction Y, a second body portion 232 adjacent to the first body portion 231 on one side in the width direction Y, and a bent-back portion 233 that connects the second body portion 232 to the first body portion 231 in a state where it can be bent back to the other side in the width direction Y.

[0123] As shown in Figure 7, when the bent second main body portion 232 is unfolded, the clamp main body 23 has a predetermined thickness in the vertical direction and is formed in a roughly rectangular plate shape in plan view that is long in the width direction Y.

[0124] Specifically, as shown in Figure 7, the clamp body 23 in the unfolded state is composed of four hinge portions 24 that enable bending to the other side in the width direction Y at positions spaced apart at a predetermined interval in the width direction Y, and five flat plate portions 25 connected by the hinge portions 24.

[0125] Furthermore, as shown in Figures 5 to 7, on the underside of the clamp body 23, five pairs of locking portions 26 are erected downward, which are locked into the insertion holes 22 when the clamp body 23 is bent back to the other side in the width direction Y.

[0126] The four hinge portions 24 are formed so as to be able to bend back to the other side in the width direction Y while rotating the second main body portion 232 downward. Specifically, as shown in Figures 6 and 7, the four hinge portions 24 are formed by thinning portions cut out on the upper surface side of the clamp main body 23 so as to have a generally V-shaped groove shape in a front-to-back direction X and tapered downward.

[0127] As shown in Figures 5 and 6, this type of clamp 20 has one of the four hinge portions 24 as a bent-back portion 233, and the second main body portion 232 on one side of the bent-back portion 233 in the width direction Y is bent back to the other side in the width direction Y, thereby making it possible to change the length in the width direction Y.

[0128] As shown in Figures 5 and 6, the clamp 20 fixes the bent-back second main body portion 232 together with the wire harness WH using a cable tie 2 to the first main body portion 231 on the other side in the width direction Y than the bent-back portion 233, thereby fixing the wire harness WH passing through a position spaced apart from the anchor fixing portion 3a to the vehicle body 3.

[0129] Here, to facilitate the following explanation, the end face on one side of the clamp body 23 in the width direction Y will be referred to as the harness side end face, and the end face on the other side of the clamp body 23 in the width direction Y will be referred to as the vehicle body side end face.

[0130] Furthermore, the clamp body 23 will be described in detail below, with the eight boundary positions (positions of the dotted lines in Figure 7) when the space between the harness side end face and the vehicle body side end face is divided into nine equal parts, referred to in order from the vehicle body side end face to one side in the width direction Y as the first boundary position P1, the second boundary position P2, the third boundary position P3, the fourth boundary position P4, the fifth boundary position P5, the sixth boundary position P6, the seventh boundary position P7, and the eighth boundary position P8.

[0131] In detail, of the four hinge portions 24, the first and second hinge portions 24 are composed of a first hinge portion 24a provided at approximately the same position as the third boundary position P3 in the width direction Y, and a second hinge portion 24b provided at approximately the same position as the fourth boundary position P4, as shown in Figure 7.

[0132] Furthermore, of the four hinge portions 24, the third and fourth hinge portions 24 are composed of a third hinge portion 24c located at approximately the same position as the fifth boundary position P5 and a fourth hinge portion 24d located at approximately the same position as the sixth boundary position P6, as shown in Figure 7.

[0133] Furthermore, of the five flat plate portions 25, the first and second flat plate portions 15 are composed of a first flat plate portion 25a on the other side of the first hinge portion 24a in the width direction Y, and a second flat plate portion 25b between the first hinge portion 24a and the second hinge portion 24b, as shown in Figure 7.

[0134] Furthermore, of the five flat plate portions 25, the third to fifth flat plate portions 15 are composed of a third flat plate portion 25c between the second hinge portion 24b and the third hinge portion 24c, a fourth flat plate portion 25d between the third hinge portion 24c and the fourth hinge portion 24d, and a fifth flat plate portion 25e on one side of the fourth hinge portion 24d in the width direction Y, as shown in Figure 7.

[0135] As shown in FIG. 7, the first flat plate portion 25a of the clamp body 23 has an anchor portion 21 provided on the upper surface thereof at approximately the center in the width direction Y between the vehicle body side end surface and the first boundary position P1. Furthermore, as shown in Figure 7(b), of the five pairs of locking portions 26 mentioned above, the first pair of locking portions 26 counting from the vehicle body side end face (hereinafter referred to as a pair of first locking portions 26a) and the second pair of locking portions 26 counting from the vehicle body side end face (hereinafter referred to as a pair of second locking portions 26b) are erected on the underside of the first flat plate portion 25a.

[0136] In addition, as shown in Figure 7, the first flat plate portion 25a has, of the eight insertion holes 22 mentioned above, the first insertion hole 22 (hereinafter referred to as the first insertion hole 22a) counting from the vehicle body side end face and the second insertion hole 22 (hereinafter referred to as the second insertion hole 22b) counting from the vehicle body side end face.

[0137] In addition, as shown in Figure 7, the second flat plate portion 25b of the clamp body 23 has an opening formed therein that is the third insertion hole 22 (hereinafter referred to as the third insertion hole 22c) of the eight insertion holes 22 mentioned above, counting from the vehicle body side end face.

[0138] Furthermore, as shown in FIG. 7, the third flat plate portion 25c of the clamp body 23 is formed with a fourth insertion hole 22 (hereinafter referred to as the fourth insertion hole 22d) counting from the vehicle body side end face, and a third pair of locking portions 26 (hereinafter referred to as a pair of third locking portions 26c) counting from the vehicle body side end face, out of the eight insertion holes 22 mentioned above.

[0139] In addition, as shown in Figure 7, the fourth flat plate portion 25d of the clamp body 23 has a fifth insertion hole 22 (hereinafter referred to as the fifth insertion hole 22e) of the eight insertion holes 22 mentioned above, counting from the vehicle body side end face, opened.

[0140] In addition, as shown in Figure 7, the fifth flat plate portion 25e of the clamp body 23 has a sixth insertion hole 22 (hereinafter referred to as the sixth insertion hole 22f) counting from the vehicle body side end face, a seventh insertion hole 22 (hereinafter referred to as the seventh insertion hole 22g) counting from the vehicle body side end face, and an eighth insertion hole 22 (hereinafter referred to as the eighth insertion hole 22h) opened.

[0141] In addition, as shown in Figure 7(b), the fifth flat plate portion 25e is formed with a fourth pair of locking portions 26 (hereinafter referred to as a pair of fourth locking portions 26d) counting from the vehicle body side end face, and a fifth pair of locking portions 26 (hereinafter referred to as a pair of fifth locking portions 26e) counting from the vehicle body side end face.

[0142] As shown in FIG. 7, the eight insertion holes 22 are openings that are elongated in the front-rear direction X and have a generally rectangular shape in plan view, and are formed at equal intervals in the width direction Y. Of the eight insertion holes 22, the first insertion hole 22a, the third insertion hole 22c, the fifth insertion hole 22e, and the seventh insertion hole 22g are formed to have the same length in the front-rear direction X, as shown in FIG.

[0143] On the other hand, as shown in FIG. 7, the second insertion hole 22b, the fourth insertion hole 22d, the sixth insertion hole 22f, and the eighth insertion hole 22h are formed as openings having a generally rectangular shape in a plan view, which is longer than the length in the front-to-rear direction X of the band portion 2a of the cable tie 2 and shorter than the length in the front-to-rear direction X of the first insertion hole 22a.

[0144] Furthermore, the eight insertion holes 22 are formed so that when any one of the four hinge portions 24 is used as a bent-back portion 233 and the clamp body 23 is bent back, two or more adjacent to the bent-back portion 233 are connected to form two or more through holes.

[0145] More specifically, as shown in FIG. 7, the first insertion hole 22a is formed to open substantially at the center in the width direction Y between the first boundary position P1 and the second boundary position P2. As shown in FIG. 7, the second insertion hole 22b is formed to open substantially at the center in the width direction Y between the second boundary position P2 and the third boundary position P3.

[0146] As shown in FIG. 7, the third insertion hole 22c is formed to open substantially at the center in the width direction Y between the third boundary position P3 and the fourth boundary position P4. As shown in FIG. 7, the fourth insertion hole 22d is formed to open substantially at the center in the width direction Y between the fourth boundary position P4 and the fifth boundary position P5.

[0147] As shown in FIG. 7, the fifth insertion hole 22e is formed to open substantially at the center in the width direction Y between the fifth boundary position P5 and the sixth boundary position P6. As shown in FIG. 7, the sixth insertion hole 22f is formed to open substantially at the center in the width direction Y between the sixth boundary position P6 and the seventh boundary position P7.

[0148] As shown in FIG. 7, the seventh insertion hole 22g is formed to open substantially in the center in the width direction Y between the seventh boundary position P7 and the eighth boundary position P8. As shown in FIG. 7, the eighth insertion hole 22h is formed to open at approximately the center in the width direction Y between the eighth boundary position P8 and the harness-side end face.

[0149] As shown in FIG. 7(b), the pair of locking portions 26 are erected on the lower surface of the clamp body 23 at an interval in the front-rear direction X that is approximately the same as the length of the second insertion hole 22b in the front-rear direction X. This locking portion 26 is composed of a shaft portion (symbol omitted) extending downward from the underside of the clamp body 23, and a claw portion (symbol omitted) protruding from the tip of the shaft portion in the front-to-rear direction X, away from the other locking portion 26.

[0150] The above-mentioned five pairs of locking portions 26 are formed so as to be locked into two or more of the first insertion hole 22a, the third insertion hole 22c, the fifth insertion hole 22e, and the seventh insertion hole 22g when the clamp body 23 is bent back using any one of the four hinge portions 24 as the bent-back portion 233.

[0151] More specifically, as shown in FIG. 7(b), the pair of first locking portions 26a are formed at approximately the center in the width direction Y between the vehicle body side end surface and the first boundary position P1. As shown in Figure 7(b), the pair of second locking portions 26b are erected downward at approximately the same position in the width direction Y as the second insertion holes 22b, along the inner surfaces of the second insertion holes 22b that face each other in the front-to-rear direction X.

[0152] As shown in Figure 7(b), the pair of third locking portions 26c are erected downward at approximately the same position in the width direction Y as the fourth insertion hole 22d, along the inner surface of the fourth insertion hole 22d that faces them in the front-to-rear direction X. As shown in Figure 7(b), the pair of fourth locking portions 26d are erected downward at approximately the same position in the width direction Y as the sixth insertion hole 22f, along the inner surface of the sixth insertion hole 22f that faces them in the front-to-rear direction X. As shown in Figure 7(b), the pair of fifth locking portions 26e are erected downward at approximately the same position in the width direction Y as the eighth insertion hole 22h, along the inner surface of the eighth insertion hole 22h that faces each other in the front-to-rear direction X.

[0153] Next, we will briefly explain the state of the clamp 20 when the length in the width direction Y is changed by setting any one of the first hinge portion 24a, the second hinge portion 24b, the third hinge portion 24c, and the fourth hinge portion 24d as the bent-back portion 233.

[0154] For example, if the third hinge portion 24c is the bent-back portion 233, the first main body portion 231 of the clamp 20 is composed of a first flat plate portion 25a, a first hinge portion 24a, a second flat plate portion 25b, a second hinge portion 24b, and a third flat plate portion 25c, as shown in Figures 5 and 6. On the other hand, as shown in FIGS. 5 and 6, the second main body portion 232 of the clamp 20 is made up of a fourth flat plate portion 25d, a fourth hinge portion 24d, and a fifth flat plate portion 25e.

[0155] In this case, as shown in Figure 6, when the second main body portion 232 overlaps the first main body portion 231, the four insertion holes 22 of the second main body portion 232 adjacent to the bent-back portion 233 and the four insertion holes 22 of the first main body portion 231 adjacent to the bent-back portion 233 are connected in the vertical direction.

[0156] Specifically, in the clamp 20, the fifth insertion hole 22e of the second main body portion 232 is connected to the fourth insertion hole 22d of the first main body portion 231, and the sixth insertion hole 22f of the second main body portion 232 is connected to the third insertion hole 22c of the first main body portion 231.

[0157] Furthermore, in the clamp 20, the seventh insertion hole 22g of the second main body portion 232 is connected to the second insertion hole 22b of the first main body portion 231, and the eighth insertion hole 22h of the second main body portion 232 is connected to the first insertion hole 22a of the first main body portion 231.

[0158] At this time, as shown in Figure 6, the second locking portion 26b and the third locking portion 26c of the first main body portion 231 of the clamp 20 are locked to the second main body portion 232 via the seventh insertion hole 22g and the fifth insertion hole 22e, respectively.

[0159] Furthermore, as shown in FIG. 6, the clamp 20 has the fourth locking portion 26d and the fifth locking portion 26e of the second main body portion 232 locked to the first main body portion 231 via the third insertion hole 22c and the first insertion hole 22a, respectively.

[0160] In other words, when the second main body portion 232 overlaps the first main body portion 231, the locking portions 26 of the clamp 20 are formed so that the locking portions 26 of the first main body portion 131 and the locking portions 26 of the second main body portion 232 are positioned alternately along the width direction Y.

[0161] With respect to the clamp 20 whose length in the width direction Y is changed in this manner, the wire harness WH is disposed between the fifth insertion hole 22e and the sixth insertion hole 22f, as shown in Fig. 6. Furthermore, as shown in Fig. 6, the binding band 2 is inserted through the fourth insertion hole 22d and the fifth insertion hole 22e, which are connected to each other, and the third insertion hole 22c and the sixth insertion hole 22f, which are connected to each other.

[0162] The band portion 2a of the binding band 2 is wound around the wire harness WH and is locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which the wire harness WH is attached to the clamp 20.

[0163] At this time, the second main body portion 232 overlaps the first hinge portion 24a, and thus the second main body portion 232 of the clamp 20 restricts deformation of the clamp main body 23 with the first hinge portion 24a as a fulcrum.

[0164] Furthermore, by overlapping the second hinge portion 14b of the first main body portion 231 and the fourth hinge portion of the second main body portion 232, the clamp 20 restricts deformation of the clamp main body 23 with the second hinge portion 24b or the fourth hinge portion 24d as the fulcrum by the other hinge portion.

[0165] As described above, the clamp 20 and clamp-equipped wire harness 1 of Example 2 have a clamp body 23 including a first body portion 231, a second body portion 232, and a bent-back portion 233, and the second body portion 232 is fixed to the first body portion 231 together with the wire harness WH by the cable tie 2, and therefore can achieve the same effects as those of Example 1 described above.

[0166] Furthermore, the clamp 20 is provided with a locking portion 26 on one of the overlapping first main body portion 231 and second main body portion 232, which protrudes from one to the other and is locked to the other.

[0167] According to this configuration, the overlapping first body portion 231 and second body portion 232 are connected by the locking portion 26, so that when, for example, fixing a wire harness WH to the clamp body 23, the worker does not have to grasp the first body portion 231 and the second body portion 232 and take the trouble of maintaining the first body portion 231 and the second body portion 232 in an overlapping state. As a result, the clamp 20 makes it easy to insert the binding band 2 into the insertion hole 22, thereby improving the ease of binding work when fixing the wire harness WH.

[0168] In addition, the clamp 20 has the locking portions 26 provided on the first main body portion 231 and the second main body portion 232, respectively. Furthermore, in the clamp 20, when the first main body portion 231 and the second main body portion 232 are overlapped, the locking portions 26 of the first main body portion 231 and the locking portions 26 of the second main body portion 232 are arranged alternately along the width direction Y.

[0169] According to this configuration, the locking portions 26 of the first main body portion 231 and the locking portions 26 of the second main body portion 232 are arranged alternately along the width direction Y, so that when the clamp body 23 bends back the second main body portion 232 at the bending portion 233, there is no interference between the locking portions 26 of the first main body portion 231 and the locking portions 26 of the second main body portion 232. This allows the clamp 20 to reliably overlap the second body portion 232 on the first body portion 231, thereby further improving the ease of tying the binding band 2.

[0170] Further, a locking portion 26 is erected on the lower surface of the clamp body 23 and is configured to be locked in the insertion hole 22 . According to this configuration, the clamp 20 can prevent the clamp body 23 from becoming larger in size in the front-rear direction X, compared to when the locking portions 26 are provided on the front and rear surfaces of the clamp body 23.

[0171] Furthermore, because locking portions 26 are locked into insertion holes 22, clamp 20 can effectively utilize multiple insertion holes 22 provided in clamp body 23 not only as openings through which cable ties 2 are inserted, but also as openings through which locking portions 26 are locked. Therefore, clamp 20 can prevent a decrease in the rigidity of clamp body 23 compared to when separate openings through which locking portions are locked are provided. [Example]

[0172] The clamp-equipped wire harness 1 of Example 3 has a different clamp shape from that of Example 2. The clamp-equipped wire harness 1 of Example 3 will be described with reference to Figs.

[0173] 8A and 8B are explanatory diagrams illustrating the appearance of the clamp-equipped wire harness 1 of Example 3, where FIG. 8A shows an external perspective view of the clamp-equipped wire harness 1 as viewed from above and in the front, and FIG. 8B shows an external perspective view of the clamp-equipped wire harness 1 as viewed from below and in the front.

[0174] Furthermore, Figure 9 shows a cross-sectional view taken along the CC arrow in Figure 8, and Figure 10 is an explanatory diagram illustrating the appearance of the clamp 30 in the deployed state, with Figure 10(a) showing an oblique view of the appearance of the clamp 30 as viewed from above and in the front, and Figure 10(b) showing an oblique view of the appearance of the clamp 30 as viewed from below and in the front. Moreover, the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0175] As shown in Figures 8 and 9, the clamp-equipped wire harness 1 of Example 3 includes a wire harness WH passing through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y, a clamp 30 that fixes the wire harness WH to the anchor fixing portion 3a, and a cable tie 2 that ties the wire harness WH to the clamp 30.

[0176] As shown in Figures 8 to 10, the clamp 30 of Example 3 is composed of an anchor portion 31 that engages with the anchor fixing portion 3a, and a roughly belt-shaped clamp body 33 that extends from the anchor portion 31 to one side in the width direction Y and has six insertion holes 32 opened at intervals in the width direction Y through which the cable ties 2 are inserted. The anchor portion 31 of the clamp 30 has the same configuration as the anchor portion 11 of the clamp 10 in the first embodiment, and therefore a detailed description thereof will be omitted.

[0177] On the other hand, as shown in Figures 8 and 9, the clamp body 33 of the clamp 30 is configured to be able to be bent back to the other side in the width direction Y, and includes a plate-shaped first body portion 331 extending from the anchor portion 31 to one side in the width direction Y, a second body portion 332 adjacent to the first body portion 331 on one side in the width direction Y, and a bent-back portion 333 connecting the second body portion 332 to the first body portion 331 in a state where it can be bent back to the other side in the width direction Y.

[0178] As shown in Figure 10, when the bent second main body portion 332 is unfolded, the clamp main body 33 has a predetermined thickness in the vertical direction and is formed into a roughly rectangular plate shape in plan view that is long in the width direction Y.

[0179] Specifically, as shown in Figure 10, the clamp body 33 in the unfolded state is composed of three hinge portions 34 that enable bending to the other side in the width direction Y at positions spaced a predetermined distance apart in the width direction Y, and four flat plate portions 35 connected by the hinge portions 34.

[0180] The three hinge portions 34 are formed so as to be able to bend back to the other side in the width direction Y while rotating the second main body portion 332 downward. Specifically, as shown in Figures 9 and 10, the three hinge portions 34 are formed by thinning portions obtained by cutting out the upper surface side of the clamp main body 33 so as to have a generally V-shaped groove shape in a front view that tapers downward and extends in the front-rear direction X.

[0181] Furthermore, as shown in Figures 8 to 10, the clamp body 33 has three pairs of locking holes 36 formed adjacent to the insertion holes 22, and when bent back to the other side in the width direction Y, four sets of locking portions 37 are erected downward to be locked into the locking holes 36.

[0182] As shown in Figures 8 and 9, this type of clamp 30 has one of the four hinge portions 34 as a bent-back portion 333, and the second main body portion 332 on one side of the bent-back portion 333 in the width direction Y is bent back to the other side in the width direction Y, thereby making it possible to change the length in the width direction Y.

[0183] As shown in Figures 8 and 9, the clamp 30 fixes the bent-back second main body portion 332 together with the wire harness WH using a cable tie 2 to the first main body portion 331 on the other side in the width direction Y of the bent-back portion 333, thereby fixing the wire harness WH passing through a position spaced apart from the anchor fixing portion 3a to the vehicle body 3.

[0184] Here, to facilitate the following explanation, the end face on one side of the clamp body 33 in the width direction Y will be referred to as the harness side end face, and the end face on the other side of the clamp body 33 in the width direction Y will be referred to as the vehicle body side end face.

[0185] Furthermore, the clamp body 33 will be described in detail below, with the six boundary positions (positions of the dotted lines in Figure 10) when the space between the harness side end face and the vehicle body side end face is divided into seven equal parts, referred to in order from the vehicle body side end face toward one side in the width direction Y as the first boundary position P1, the second boundary position P2, the third boundary position P3, the fourth boundary position P4, the fifth boundary position P5, and the sixth boundary position P6.

[0186] More specifically, of the three hinge portions 34, the first hinge portion 34 is composed of a first hinge portion 34a that is provided at approximately the same position as the third boundary position P3 in the width direction Y, as shown in FIG.

[0187] Furthermore, of the three hinge portions 34, the second and third hinge portions 34 are composed of a second hinge portion 34b located at approximately the same position as the fourth boundary position P4 and a third hinge portion 34c located at approximately the same position as the fifth boundary position P5, as shown in Figure 10.

[0188] Furthermore, of the four flat plate portions 35, the first and second flat plate portions 35 are composed of a first flat plate portion 35a on the other side of the first hinge portion 34a in the width direction Y, and a second flat plate portion 35b between the first hinge portion 34a and the second hinge portion 34b, as shown in Figure 10.

[0189] Furthermore, of the four flat plate portions 35, the third and fourth flat plate portions 35 are composed of a third flat plate portion 35c between the second hinge portion 34b and the third hinge portion 34c, and a fourth flat plate portion 35d on one side of the third hinge portion 34c in the width direction Y, as shown in Figure 10.

[0190] As shown in FIG. 10, the first flat plate portion 35a of the clamp body 33 has an anchor portion 31 provided on the upper surface thereof at approximately the center in the width direction Y between the vehicle body side end surface and the first boundary position P1. Furthermore, as shown in Figure 10(b), of the four sets of locking portions 37 described above, the first set of locking portions 37 (hereinafter referred to as the set of first locking portions 37a) and the second set of locking portions 37 (hereinafter referred to as the set of second locking portions 37b) are erected on the underside of the first flat plate portion 35a, counting from the vehicle body side end face.

[0191] Furthermore, as shown in Figure 10, the first flat plate portion 35a is formed with the first insertion hole 32 (hereinafter referred to as the first insertion hole 32a) counting from the vehicle body side end face, and the second insertion hole 32 (hereinafter referred to as the second insertion hole 32b) counting from the vehicle body side end face, out of the six insertion holes 32 mentioned above.

[0192] In addition, as shown in Figure 10, the first flat plate portion 35a is formed with the first pair of locking holes 36 (hereinafter referred to as the pair of first locking holes 36a) of the four pairs of locking holes 36 described above, counting from the vehicle body side end face.

[0193] In addition, as shown in Figure 10, the second flat plate portion 35b of the clamp body 33 is formed with a third insertion hole 32 (hereinafter referred to as the third insertion hole 32c) counting from the vehicle body side end face, and a pair of second engagement holes 36 (hereinafter referred to as a pair of second engagement holes 36b) counting from the vehicle body side end face.

[0194] In addition, as shown in Figure 10, the third flat plate portion 35c of the clamp body 33 is formed with a fourth insertion hole 32 (hereinafter referred to as the fourth insertion hole 32d) counting from the vehicle body side end face and a third set of locking portions 37 (hereinafter referred to as the third set of locking portions 37c) counting from the vehicle body side end face.

[0195] In addition, as shown in Figure 10, the fourth flat plate portion 35d of the clamp body 33 has a fifth insertion hole 32 (hereinafter referred to as the fifth insertion hole 32e) and a sixth insertion hole 32 (hereinafter referred to as the sixth insertion hole 32f) formed therein, counting from the vehicle body side end face.

[0196] Furthermore, as shown in Figure 10, the fourth flat plate portion 35d is formed with a third pair of locking holes 36 (hereinafter referred to as a pair of third locking holes 36c) counting from the vehicle body side end face, and a fourth set of locking portions 37 (hereinafter referred to as a set of fourth locking portions 37d) counting from the vehicle body side end face. As shown in FIG. 10, the six insertion holes 32 are openings that are elongated in the front-rear direction X and have a generally rectangular shape in plan view, and are formed at equal intervals in the width direction Y. Furthermore, the six insertion holes 32 are formed so that when any one of the three hinge portions 34 is used as a bent-back portion 333 and the clamp body 33 is bent back, four or more adjacent to the bent-back portion 333 are connected to form two or more through holes.

[0197] More specifically, as shown in FIG. 10, the first insertion hole 32a is formed to open substantially at the center in the width direction Y between the first boundary position P1 and the second boundary position P2. As shown in FIG. 10, the second insertion hole 32b is formed to open substantially at the center in the width direction Y between the second boundary position P2 and the third boundary position P3.

[0198] As shown in FIG. 10, the third insertion hole 32c is formed to open substantially at the center in the width direction Y between the third boundary position P3 and the fourth boundary position P4. As shown in FIG. 10, the fourth insertion hole 32d is formed to open substantially in the center in the width direction Y between the fourth boundary position P4 and the fifth boundary position P5.

[0199] As shown in FIG. 10, the fifth insertion hole 32e is formed to open substantially at the center in the width direction Y between the fifth boundary position P5 and the sixth boundary position P6. As shown in FIG. 10, the sixth insertion hole 32f is formed to open at approximately the center in the width direction Y between the sixth boundary position P6 and the harness-side end face.

[0200] Furthermore, as shown in Figure 10, the three pairs of engagement holes 36 described above are openings of approximately the same size as the insertion hole 32, and are formed at positions opposite each other in the width direction Y, sandwiching the insertion hole 32 therebetween. More specifically, as shown in Figure 10, the pair of first locking holes 36a are formed at positions facing each other in the width direction Y, sandwiching the first insertion hole 32a, between the first boundary position P1 and the second boundary position P2.

[0201] As shown in FIG. 10, the pair of second locking holes 36b are formed at positions facing each other in the width direction Y, sandwiching the third insertion hole 32c, between the third boundary position P3 and the fourth boundary position P4. As shown in FIG. 10, the pair of third locking holes 36c are formed at positions facing each other in the width direction Y, sandwiching the fifth insertion hole 32e, between the fifth boundary position P5 and the sixth boundary position P6.

[0202] As shown in FIG. 10(b), the set of locking portions 37 is configured by a pair of locking portions 37 that are erected at a distance in the front-to-rear direction X that is longer than the length of the band portion 2a of the cable tie 2 in the front-to-rear direction X and narrower than the length of the insertion hole 32 in the front-to-rear direction X, and are arranged opposite each other at approximately the same distance in the width direction Y in the locking hole 36. The locking portion 37 is formed in a shape having a claw portion at the lower end that protrudes toward the opposing locking portion 37 in the width direction Y.

[0203] The above-mentioned four sets of locking portions 37 are formed so as to be locked into two or more of the pair of first locking holes 36a, the pair of second locking holes 36b, and the pair of third locking holes 36c when the clamp body 33 is bent back using one of the three hinge portions 34 as a bent-back portion 333.

[0204] More specifically, as shown in Figure 10, the pair of first locking portions 37a are formed between the vehicle body side end face and the first boundary position P1 so that the pair of locking portions 37 are line-symmetrical at approximately the center position in the width direction Y. As shown in Figure 10, the pair of second locking portions 37b are formed between the second boundary position P2 and the third boundary position P3 so that the pair of locking portions 37 are line-symmetrical at approximately the center position in the width direction Y.

[0205] As shown in Figure 10, the set of third locking portions 37c is formed between the fourth boundary position P4 and the fifth boundary position P5 so that the pair of locking portions 37 are line-symmetrical at approximately the center position in the width direction Y. As shown in Figure 10, the set of fourth locking portions 37d is formed between the sixth boundary position P6 and the harness side end face so that the pair of locking portions 37 are line-symmetrical at approximately the center position in the width direction Y.

[0206] Next, a brief description will be given of the state of the clamp 30 in which the length in the width direction Y is changed by using one of the first hinge portion 34a, the second hinge portion 34b, and the third hinge portion 34c as the bent-back portion 333.

[0207] For example, if the second hinge portion 34b is the bent-back portion 333, the first main body portion 331 of the clamp 30 is composed of the first flat plate portion 35a, the first hinge portion 34a, and the second flat plate portion 35b, as shown in Figures 8 and 9. On the other hand, as shown in FIGS. 8 and 9, the second main body portion 332 of the clamp 30 is made up of a third flat plate portion 35c, a third hinge portion 34c, and a fourth flat plate portion 35d.

[0208] In this case, as shown in Figure 9, when the second main body portion 332 overlaps the first main body portion 331 of the clamp 30, the four insertion holes 32 of the second main body portion 332 adjacent to the bent-back portion 333 and the four insertion holes 32 of the first main body portion 331 adjacent to the bent-back portion 333 are connected in the vertical direction.

[0209] Specifically, in the clamp 30, the fourth insertion hole 32d of the second main body portion 332 is connected to the third insertion hole 32c of the first main body portion 331, and the fifth insertion hole 32e of the second main body portion 332 is connected to the second insertion hole 32b of the first main body portion 331. Furthermore, in the clamp 30, the sixth insertion hole 32f of the second main body portion 332 and the first insertion hole 32a of the first main body portion 331 communicate with each other.

[0210] 9, the second locking portion 37b of the first main body portion 331 of the clamp 30 is locked to the second main body portion 332 via the third locking hole 36c. Furthermore, the third locking portion 37c and the fourth locking portion 37d of the second main body portion 332 of the clamp 30 are locked to the first main body portion 331 via the second locking hole 36b and the first locking hole 36a, respectively.

[0211] In other words, when the second main body portion 332 overlaps the first main body portion 331, the locking portions 37 of the clamp 30 are formed so that the locking portions 37 of the first main body portion 131 and the locking portions 37 of the second main body portion 332 are positioned alternately along the width direction Y.

[0212] With respect to the clamp 30 whose length in the width direction Y is changed in this manner, the wire harness WH is disposed between the fourth insertion hole 32d and the fifth insertion hole 32e, as shown in Fig. 9. Furthermore, as shown in Fig. 9, the binding band 2 is inserted through the third insertion hole 32c and the fourth insertion hole 32d, which are connected to each other, and the second insertion hole 32b and the fifth insertion hole 32e, which are connected to each other.

[0213] The band portion 2a of the binding band 2 is wrapped around the wire harness WH and locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which the wire harness WH is attached to the clamp 30.

[0214] At this time, the first hinge portion 34a of the first main body portion 331 and the third hinge portion 34c of the second main body portion 332 overlap with each other, so that the clamp 30 restricts deformation of the clamp main body 33 with the first hinge portion 34a or the third hinge portion 34c as the fulcrum by the other hinge portion.

[0215] As described above, the clamp 30 and clamp-equipped wire harness 1 of Example 3 have a clamp body 33 including a first body portion 331, a second body portion 332, and a bent-back portion 333, and the second body portion 332 is fixed to the first body portion 331 together with the wire harness WH by the cable tie 2, and therefore can achieve the same effects as those of Example 1 described above.

[0216] Furthermore, since one of the overlapping first main body portion 331 and second main body portion 332 is provided with a locking portion 37 that protrudes from one to the other and locks onto the other, clamp 30 can achieve the same effect as in Example 2 described above. [Example]

[0217] The clamp-equipped wire harness 1 of Example 4 has a different clamp shape from that of Example 1. The clamp-equipped wire harness 1 of Example 4 will be described with reference to Figs.

[0218] 11A and 11B are explanatory diagrams illustrating the appearance of the clamp-equipped wire harness 1 of Example 4, where FIG. 11A shows an external perspective view of the clamp-equipped wire harness 1 as viewed from above and in the front, and FIG. 11B shows an external perspective view of the clamp-equipped wire harness 1 as viewed from below and in the front.

[0219] Furthermore, Figure 12 is an explanatory diagram showing the clamp-equipped wire harness 1 in cross section, where Figure 12(a) shows a cross section taken along the line DD in Figure 11, and Figure 12(b) shows a cross section taken along the line EE in Figure 12(a).

[0220] In addition, Figure 13 is an explanatory diagram illustrating the appearance of the clamp 30 in the deployed state, where Figure 13(a) shows an oblique view of the appearance of the clamp 30 as viewed from above and in the front, and Figure 13(b) shows an oblique view of the appearance of the clamp 30 as viewed from below and in the front. Moreover, the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0221] As shown in Figures 11 and 12, the clamp-equipped wire harness 1 of Example 4 includes two wire harnesses WH passing through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y, a clamp 40 that fixes the two wire harnesses WH to the anchor fixing portion 3a, and two cable ties 2 that respectively tie the two wire harnesses WH to the clamp 40.

[0222] As shown in Figures 11 to 13, the clamp 40 of Example 4 is composed of an anchor portion 41 that engages with the anchor fixing portion 3a, and a roughly belt-shaped clamp body 43 that extends from the anchor portion 41 to one side in the width direction Y and has six pairs of insertion holes 42 opened at intervals in the width direction Y, through which the cable ties 2 are inserted. The anchor portion 41 of the clamp 10 has the same configuration as the anchor portion 11 of the clamp 10 in the first embodiment, and therefore a detailed description thereof will be omitted.

[0223] On the other hand, as shown in Figures 11 and 12, the clamp body 43 of the clamp 40 is configured to be bendable to the other side in the width direction Y, and includes a plate-shaped first body portion 431 extending from the anchor portion 41 to one side in the width direction Y, a second body portion 432 adjacent to the first body portion 431 on one side in the width direction Y, and a bending portion 433 connecting the second body portion 432 to the first body portion 431 in a state where it can be bent to the other side in the width direction Y.

[0224] As shown in Figure 13, when the bent second main body portion 432 is unfolded, the clamp main body 43 has a predetermined thickness in the vertical direction and is formed into a roughly rectangular shape in plan view that is long in the width direction Y.

[0225] Specifically, as shown in Figure 13, the clamp body 43 in the unfolded state is composed of five hinge portions 44 at positions spaced apart by a predetermined distance in the width direction Y, which enable bending to the other side in the width direction Y, six bottom plate portions 45 connected by the hinge portions 44, and a pair of side wall portions 46 erected upward from both ends in the front-to-rear direction X.

[0226] Furthermore, as shown in Figure 13, the clamp body 43 has a through hole 47 formed along a pair of side wall portions 46 at approximately the same position in the width direction Y as the hinge portion 44, which penetrates in the vertical direction across the adjacent bottom plate portion 45 in the width direction Y.

[0227] The five hinge portions 44 are formed so as to be able to bend back to the other side in the width direction Y while rotating the second main body portion 432 downward. Specifically, as shown in Figures 11 and 12, the five hinge portions 44 are formed by thinning portions obtained by cutting out the upper surface side of the clamp main body 43 so as to have a generally V-shaped groove shape in a front-to-back direction X and tapering downward.

[0228] As shown in Figures 11 and 12, this type of clamp 40 has one of the five hinge portions 44 as a bent-back portion 433, and the second main body portion 432 on one side of the bent-back portion 433 in the width direction Y is bent back to the other side in the width direction Y, thereby making it possible to change the length in the width direction Y.

[0229] As shown in Figures 11 and 12, the clamp 40 fixes the bent-back second main body portion 432 together with the wire harness WH using a cable tie 2 to the first main body portion 431 on the other side in the width direction Y than the bent-back portion 433, thereby fixing the wire harness WH passing through a position spaced apart from the anchor fixing portion 3a to the vehicle body 3.

[0230] Here, to facilitate the following explanation, the end face on one side of the clamp body 43 in the width direction Y will be referred to as the harness side end face, and the end face on the other side of the clamp body 43 in the width direction Y will be referred to as the vehicle body side end face.

[0231] Furthermore, the clamp body 43 will be described in detail below, with the six boundary positions (positions of the dotted lines in Figure 13) when the space between the harness side end face and the vehicle body side end face is divided into seven equal parts, referred to in order from the vehicle body side end face toward one side in the width direction Y as the first boundary position P1, the second boundary position P2, the third boundary position P3, the fourth boundary position P4, the fifth boundary position P5, and the sixth boundary position P6.

[0232] In detail, of the five hinge portions 44, the first and second hinge portions 44 are composed of a first hinge portion 44a provided at approximately the same position in the width direction Y at the second boundary position P2, and a second hinge portion 44b provided at approximately the same position at the third boundary position P3, as shown in Figure 13.

[0233] Furthermore, of the five hinge portions 44, the third to fifth hinge portions 44 are composed of a third hinge portion 44c located at approximately the same position as the fourth boundary position P4, a fourth hinge portion 44d located at approximately the same position as the fifth boundary position P5, and a fifth hinge portion 44e located at approximately the same position as the sixth boundary position P6, as shown in Figure 13.

[0234] Furthermore, of the six bottom plate portions 45, the first and second bottom plate portions 45 are composed of a first bottom plate portion 45a on the other side of the first hinge portion 44a in the width direction Y, and a second bottom plate portion 45b between the first hinge portion 44a and the second hinge portion 44b, as shown in Figure 13.

[0235] Furthermore, of the six bottom plate portions 45, the third and fourth bottom plate portions 45 are composed of a third bottom plate portion 45c between the second hinge portion 44b and the third hinge portion 44c, and a fourth bottom plate portion 45d between the third hinge portion 44c and the fourth hinge portion 44d, as shown in Figure 13.

[0236] In addition, of the six bottom plate portions 45, the fifth and sixth bottom plate portions 45 are composed of a fifth bottom plate portion 45e between the fourth hinge portion 44d and the fifth hinge portion 44e, and a sixth bottom plate portion 45f on one side of the fifth hinge portion 44e in the width direction Y, as shown in Figure 13.

[0237] As shown in FIG. 13, the first bottom plate portion 45a of the clamp body 43 has an anchor portion 41 provided on the upper surface thereof at approximately the center in the width direction Y between the vehicle body side end surface and the first boundary position P1. The first bottom plate portion 45a is formed to be thicker between the vehicle body side end face and the first boundary position P1 than between the first boundary position P1 and the second boundary position P2.

[0238] Furthermore, as shown in FIG. 13, the first bottom plate portion 45a is formed with the first pair of insertion holes 42, counting from the end surface on the vehicle body side, out of the six pairs of insertion holes 42 described above. 13, the second bottom plate portion 45b of the clamp body 43 is formed with a second pair of insertion holes 42, counting from the end surface on the vehicle body side.

[0239] 13, the third bottom plate portion 45c of the clamp body 43 is formed with a third pair of insertion holes 42, counting from the end surface on the vehicle body side. As shown in FIG. 13, the fourth bottom plate portion 45d of the clamp body 43 is formed with a fourth pair of insertion holes 42, counting from the end surface on the vehicle body side.

[0240] 13, the fifth bottom plate portion 45e of the clamp body 43 is formed with a fifth pair of insertion holes 42, counting from the end surface on the vehicle body side. 13, the sixth bottom plate portion 45f of the clamp body 43 is formed with a sixth pair of insertion holes 42, counting from the end surface on the vehicle body side.

[0241] The six insertion holes 42 described above are formed so that when any one of the five hinge portions 44 is used as a bent-back portion 433 and the clamp body 43 is bent back, four or more adjacent to the bent-back portion 433 are connected to form two or more through holes.

[0242] 13, the pair of insertion holes 42 are formed in a generally rectangular shape in plan view and are elongated in the front-rear direction X. The pair of insertion holes 42 are formed near the ends of the bottom plate portion 45 in the width direction Y so as to be line-symmetrical about the center between adjacent boundary positions in the width direction Y.

[0243] Furthermore, as shown in Figure 13, the other side of the pair of side wall portions 46 in the width direction Y is connected to the thick portion of the first bottom plate portion 45a, and is erected in the range from the first boundary position P1 to the harness side end face.

[0244] As shown in FIGS. 12(a) and 13, the pair of side wall portions 46 are formed with a notch portion 46a in which the wire harness WH is disposed, the notch portion 46a being positioned between the pair of insertion holes 42.

[0245] Specifically, as shown in Figure 12(a), the cutout portion 46a is formed by cutting out the upper end of the side wall portion 46 between adjacent boundary positions in the width direction Y, in a generally arc-shaped portion when viewed from the front that protrudes downward.

[0246] The cutout portion 46a is generally arc-shaped when viewed from the front, with a diameter slightly larger than the diameter of the wire harness WH, and is cut out so that the center of the generally arc-shaped portion when viewed from the front is located on a vertical imaginary line passing through the center in the width direction Y between adjacent boundary positions.

[0247] Furthermore, the pair of side wall portions 46 have separation portions 46b formed at approximately the same position in the width direction Y as the first hinge portion 44a, the second hinge portion 44b, the third hinge portion 44c, the fourth hinge portion 44d, and the fifth hinge portion 44e, which allow the side wall portions 46 to be separated in the vertical direction.

[0248] 12(b), the separation portion 46b is thinned to a thickness that allows it to be easily separated, for example, by bare hands or by a cutting tool. The separation portion 46b is formed in a range in the vertical direction from the upper end of the side wall portion 46 to the lower surface of the bottom plate portion 45 via the through-hole 47.

[0249] Next, we will briefly explain the state of the clamp 40 when the length in the width direction Y is changed by setting any one of the first hinge portion 44a, the second hinge portion 44b, the third hinge portion 44c, the fourth hinge portion 44d, and the fifth hinge portion 44e as the bent-back portion 433.

[0250] In addition, in the clamp 40 of Example 4, the length of the clamp body 43 in the width direction Y is changed by cutting a separation portion 46b at the same position in the width direction Y in the bent-back portion 433 and bending back the side wall portion 46 together with the bottom plate portion 45.

[0251] For example, if the fourth hinge portion 44d is the bent-back portion 433, the first main body portion 431 of the clamp 40 is composed of a first bottom plate portion 45a, a first hinge portion 44a, a second bottom plate portion 45b, a second hinge portion 44b, a third bottom plate portion 45c, a third hinge portion 44c, and a fourth bottom plate portion 45d, as shown in Figures 11 and 12(a). On the other hand, as shown in FIGS. 11 and 12(a), the second main body portion 432 of the clamp 40 is formed by a fifth bottom plate portion 45e.

[0252] In this case, as shown in Figure 12(a), when the second main body portion 432 overlaps the first main body portion 431, the four insertion holes 42 of the second main body portion 432 adjacent to the bent-back portion 433 and the four insertion holes 42 of the first main body portion 431 adjacent to the bent-back portion 433 are connected in the vertical direction.

[0253] Specifically, as shown in Figure 12(a), the clamp 40 has a pair of insertion holes 42 in the fifth bottom plate portion 45e that are connected to a pair of insertion holes 42 in the fourth bottom plate portion 45d, and a pair of insertion holes 42 in the sixth bottom plate portion 45f that are connected to a pair of insertion holes 42 in the third bottom plate portion 45c.

[0254] For the clamp 40 whose length in the width direction Y is changed in this way, one wire harness WH is arranged between the insertion holes 42 of the fifth bottom plate portion 45e, as shown in Fig. 12(a). Furthermore, as shown in Fig. 12(a), the cable tie 2 is inserted through the insertion holes 42 of the fifth bottom plate portion 45e and the insertion holes 42 of the fourth bottom plate portion 45d, which are connected to each other.

[0255] 12(a), the other wire harness WH is disposed between the insertion holes 42 of the sixth bottom plate portion 45f. Furthermore, as shown in FIG. 12(a), the cable tie 2 is inserted through the insertion holes 42 of the sixth bottom plate portion 45f and the insertion holes 42 of the third bottom plate portion 45c, which are connected to each other.

[0256] The band portion 2a of the binding band 2 is wrapped around the wire harness WH and locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which two wire harnesses WH are attached to the clamp 40.

[0257] At this time, the pair of side walls 46 of the clamp 40 restrict deformation of the clamp body 43 around the first hinge portion 44a, the second hinge portion 44b, the third hinge portion 44c, or the fifth hinge portion 44e as a fulcrum.

[0258] As described above, the clamp 40 and clamp-equipped wire harness 1 of Example 4 have a clamp body 43 including a first body portion 431, a second body portion 432, and a bent-back portion 433, and the second body portion 432 is fixed to the first body portion 431 together with the wire harness WH by the cable tie 2, and therefore can achieve the same effects as those of Example 1 described above.

[0259] Furthermore, the clamp 40 has a pair of side walls 46 that are erected on the clamp body 43 and face each other in the front-rear direction X. The side walls 46 have separation portions 46b that are separated from the hinge portions 44 at substantially the same position in the width direction Y.

[0260] According to this configuration, the clamp body 43 can improve the rigidity of the first body portion 431 and the rigidity of the second body portion 432 by the pair of side wall portions 46. Therefore, the clamp 40 can reliably ensure the supporting rigidity of the wire harness WH.

[0261] Furthermore, since the side wall portion 46 can be separated at approximately the same position in the width direction Y as the hinge portion 44, the clamp body 43 can be easily bent back at the bent-back portion 433 even when a pair of side wall portions 46 is provided. [Example]

[0262] The clamp-equipped wire harness 1 of Example 5 has a different clamp shape from that of Example 1. The clamp-equipped wire harness 1 of Example 5 will be described with reference to Figs.

[0263] 14A and 14B are explanatory diagrams illustrating the appearance of the clamp-equipped wire harness 1 of Example 5, in which FIG. 14A shows an external perspective view of the clamp-equipped wire harness 1 as viewed from above and in the front, and FIG. 14B shows an external perspective view of the clamp-equipped wire harness 1 as viewed from below and in the front.

[0264] Furthermore, Figure 15 shows a cross-sectional view taken along the arrow FF in Figure 14, and Figure 16 is an explanatory diagram illustrating the appearance of the clamp 50 in the deployed state, with Figure 16(a) showing an oblique view of the appearance of the clamp 50 as viewed from above and in the front, and Figure 16(b) showing an oblique view of the appearance of the clamp 50 as viewed from below and in the front.

[0265] In addition, Figure 17 is an explanatory diagram showing the bending process of clamp 50 from a front downward view, where Figure 17(a) shows an external oblique view of clamp 50 during the bending process of the second main body portion 532, and Figure 17(b) shows an external oblique view of clamp 50 during the bending process of both end portions. Moreover, the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0266] As shown in Figures 14 and 15, the clamp-equipped wire harness 1 of Example 5 includes a wire harness WH passing through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y, a clamp 50 that fixes the wire harness WH to the anchor fixing portion 3a, and a cable tie 2 that ties the wire harness WH to the clamp 50.

[0267] As shown in Figures 14 to 16, the clamp 50 of Example 5 is composed of an anchor portion 51 that engages with the anchor fixing portion 3a, and a roughly belt-shaped clamp body 53 that extends from the anchor portion 51 to one side in the width direction Y and has six insertion holes 52 opened at intervals in the width direction Y through which the cable ties 2 are inserted. The anchor portion 51 of the clamp 10 has the same configuration as the anchor portion 11 of the clamp 10 in the first embodiment, and therefore a detailed description thereof will be omitted.

[0268] On the other hand, as shown in Figures 14 and 15, the clamp body 53 of the clamp 50 is configured to be bendable to the other side in the width direction Y, and includes a plate-shaped first body portion 531 extending from the anchor portion 51 to one side in the width direction Y, a second body portion 532 adjacent to the first body portion 531 on one side in the width direction Y, and a bending portion 533 that connects the second body portion 532 to the first body portion 531 in a state where it can be bent to the other side in the width direction Y.

[0269] As shown in Figure 16, when the bent second main body portion 532 is unfolded, the clamp main body 53 has a predetermined thickness in the vertical direction and is formed in the shape of a roughly rectangular plate in plan view that is long in the width direction Y. Specifically, as shown in Figure 16, the clamp body 53 in the unfolded state is composed of four short hinge portions 54 extending in the front-to-rear direction X at predetermined intervals in the width direction Y, and five flat plate portions 55 connected by the short hinge portions 54.

[0270] Furthermore, the clamp body 53 has a pair of longitudinal hinge portions 56 that foldably connect the flat plate portion 55 to a central portion (reference numeral omitted) located approximately in the center of the front-rear direction X and both end portions (reference numeral omitted) located at both ends of the central portion in the front-rear direction X. In addition, as shown in Figure 16(b), the underside of the clamp body 53 is provided with a plurality of fitting holes 57 recessed upward and a plurality of protrusions 58 protruding downward and fitting into the fitting holes 57.

[0271] The four short hinge portions 54 are formed so as to be able to bend back to the other side in the width direction Y while rotating the second main body portion 532 downward. Specifically, as shown in Figures 15 and 16, the four short hinge portions 54 are formed by thinning portions obtained by cutting out the upper surface of the clamp main body 53 so as to have a generally V-shaped groove shape in front-to-back direction X and tapered downward.

[0272] On the other hand, the pair of longitudinal hinge portions 56 are formed so as to be able to bend back while rotating both end portions of the first main body portion 531 downward. Specifically, as shown in Figures 15 and 16, the pair of longitudinal hinge portions 56 are formed by thinning portions obtained by cutting out the upper surface side of the clamp main body 53 so as to have a generally V-shaped groove shape in side view that tapers downward and extends in the width direction Y.

[0273] As shown in Figures 14 and 15, this type of clamp 50 has one of the four short hinge portions 54 as a bent-back portion 533, and the second main body portion 532 on one side of the bent-back portion 533 in the width direction Y is bent back to the other side in the width direction Y, thereby making it possible to change the length in the width direction Y.

[0274] As shown in Figures 14 and 15, the clamp 50 fixes the bent-back second main body portion 532 together with the wire harness WH using a cable tie 2 to the first main body portion 531 on the other side in the width direction Y of the bent-back portion 533, thereby fixing the wire harness WH passing through a position spaced apart from the anchor fixing portion 3a to the vehicle body 3.

[0275] Here, to facilitate the following explanation, the end face on one side of the clamp body 53 in the width direction Y will be referred to as the harness side end face, and the end face on the other side of the clamp body 53 in the width direction Y will be referred to as the vehicle body side end face.

[0276] Furthermore, the clamp body 53 will be described in detail below, with the six boundary positions (positions of the dotted lines in Figure 16) when the space between the harness side end face and the vehicle body side end face is divided into seven equal parts, referred to in order from the vehicle body side end face toward one side in the width direction Y as the first boundary position P1, the second boundary position P2, the third boundary position P3, the fourth boundary position P4, the fifth boundary position P5, and the sixth boundary position P6.

[0277] In detail, of the four short hinge portions 54, the first and second short hinge portions 54 are composed of a first hinge portion 54a provided at approximately the same position as the third boundary position P3 in the width direction Y, and a second hinge portion 54b provided at approximately the same position as the fourth boundary position P4, as shown in Figure 16.

[0278] Furthermore, of the four short hinge portions 54, the third and fourth short hinge portions 54 are composed of a third hinge portion 54c located at approximately the same position as the fifth boundary position P5 and a fourth hinge portion 54d located at approximately the same position as the sixth boundary position P6, as shown in Figure 16.

[0279] Furthermore, of the five flat plate portions 55, the first and second flat plate portions 55 are composed of a first flat plate portion 55a on the other side of the first hinge portion 54a in the width direction Y, and a second flat plate portion 55b between the first hinge portion 54a and the second hinge portion 54b, as shown in Figure 16.

[0280] Furthermore, of the five flat plate portions 55, the third to fifth flat plate portions 55 are composed of a third flat plate portion 55c between the second hinge portion 54b and the third hinge portion 54c, a fourth flat plate portion 55d between the third hinge portion 54c and the fourth hinge portion 54d, and a fifth flat plate portion 55e on one side of the fourth hinge portion 54d in the width direction Y, as shown in Figure 16.

[0281] In addition, as shown in Figure 16, the pair of longitudinal hinge portions 56 of the clamp body 53 are formed at positions spaced a predetermined distance apart in the front-to-rear direction X, with a length in the width direction Y extending from the first boundary position P1 to the harness side end face. The longitudinal hinge portion 56 divides the clamp body 53 into a central portion located approximately in the center in the front-rear direction X and both end portions located on both ends in the front-rear direction X of the central portion. The clamp body 53 is provided with notches (reference numerals omitted) at the first boundary position P1, cutting the range from both end surfaces in the front-rear direction X to the longitudinal hinge portion 56.

[0282] As shown in Figure 16, the first flat plate portion 55a of the clamp body 53 has an anchor portion 51 provided on the upper surface of the central portion, approximately in the center in the width direction Y between the vehicle body side end face and the first boundary position P1.

[0283] Furthermore, as shown in Figure 16, of the six insertion holes 52 mentioned above, the first insertion hole 52 (hereinafter referred to as the first insertion hole 52a) counting from the vehicle body side end face and the second insertion hole 52 (hereinafter referred to as the second insertion hole 52b) counting from the vehicle body side end face are formed in the central portion of the first flat plate portion 55a.

[0284] In addition, as shown in Figure 16, the second flat plate portion 55b of the clamp body 53 has a third insertion hole 52 (hereinafter referred to as the third insertion hole 52c) opening in the central portion as counted from the vehicle body side end face. In addition, as shown in Figure 16, the third flat plate portion 55c of the clamp body 53 has a fourth insertion hole 52 (hereinafter referred to as the fourth insertion hole 52d) opening in the central portion as counted from the vehicle body side end face.

[0285] In addition, as shown in Figure 16, the fourth flat plate portion 55d of the clamp body 53 has a fifth insertion hole 52 (hereinafter referred to as the fifth insertion hole 52e) opening in the central portion as counted from the vehicle body side end face. In addition, as shown in Figure 16, the fifth flat plate portion 55e of the clamp body 53 has a sixth insertion hole 52 (hereinafter referred to as the sixth insertion hole 52f) opening in the central portion as counted from the vehicle body side end face.

[0286] As shown in FIG. 16, the six insertion holes 52 are openings that are generally rectangular in plan view and are long in the front-rear direction X, and are formed at equal intervals in the width direction Y. Furthermore, the six insertion holes 52 are formed so that when any one of the four short hinge portions 54 is used as a bent-back portion 533 and the clamp body 53 is bent back, four or more adjacent to the bent-back portion 533 are connected to form two or more through holes.

[0287] More specifically, as shown in FIG. 16, the first insertion hole 52a is formed to open substantially at the center in the width direction Y between the first boundary position P1 and the second boundary position P2. As shown in FIG. 16, the second insertion hole 52b is formed to open substantially at the center in the width direction Y between the second boundary position P2 and the third boundary position P3.

[0288] As shown in FIG. 16, the third insertion hole 52c is formed to open substantially at the center in the width direction Y between the third boundary position P3 and the fourth boundary position P4. As shown in FIG. 16, the fourth insertion hole 52d is formed to open substantially in the center in the width direction Y between the fourth boundary position P4 and the fifth boundary position P5.

[0289] As shown in FIG. 16, the fifth insertion hole 52e is formed to open substantially in the center in the width direction Y between the fifth boundary position P5 and the sixth boundary position P6. As shown in FIG. 16, the sixth insertion hole 52f is formed to open at approximately the center in the width direction Y between the sixth boundary position P6 and the harness-side end face.

[0290] In addition, the above-mentioned multiple fitting holes 57 and multiple protrusions 58 are formed so that the second main body portion 532, which is bent back at any one of the four short hinge portions 54, can be fixed to the first main body portion 531, and also so that both end portions, which are bent back at the pair of long hinge portions 56, can be fixed to the central portion.

[0291] 16(b), the plurality of fitting holes 57 are arranged in a staggered pattern along the width direction Y such that pairs of fitting holes formed at a predetermined interval in the front-rear direction X are alternately positioned with the longitudinal hinge portion 56 therebetween between adjacent boundary positions in the width direction Y. Note that each fitting hole 57 is recessed in the shape of a truncated cone with a small diameter on the upper side.

[0292] Specifically, as shown in Figure 16(b), the fitting holes 57 are formed at both end portions of the first flat plate portion 55a, both end portions of the second flat plate portion 55b, and both end portions of the fourth flat plate portion 55d between the first boundary position P1 and the second boundary position P2.

[0293] Furthermore, as shown in Figure 16(b), the fitting holes 57 are formed in the central portion of the first flat plate portion 55a, the central portion of the third flat plate portion 55c, and the central portion of the fifth flat plate portion 55e between the second boundary position P2 and the third boundary position P3.

[0294] 16(b), a pair of the protrusions 58 are formed at a predetermined interval in the front-rear direction X between boundary positions adjacent to each other in the width direction Y, and are arranged at positions facing the fitting hole 57 in the front-rear direction X with the longitudinal hinge portion 56 interposed therebetween. The protrusions 58 protrude downward and are formed in the shape of a truncated cone with a smaller diameter on the lower side.

[0295] Specifically, as shown in Figure 16(b), the protrusion portion 58 is formed in the central portion of the first flat plate portion 55a, the central portion of the second flat plate portion 55b, and the central portion of the fourth flat plate portion 55d between the first boundary position P1 and the second boundary position P2.

[0296] 16(b), protrusions 58 are formed on both end portions of the first flat plate portion 55a, the third flat plate portion 55c, and the fifth flat plate portion 55e between the second boundary position P2 and the third boundary position P3. These protrusions 58 protrude downward and are formed in the shape of a truncated cone with a smaller diameter on the lower side.

[0297] Next, we will briefly explain the process of deforming the clamp 50 having the above-mentioned configuration by using one of the first hinge portion 54a, the second hinge portion 54b, the third hinge portion 54c, and the fourth hinge portion 54d as the bent-back portion 533, and the state of the clamp 50 when the length in the width direction Y is changed.

[0298] First, for example, if the third hinge portion 54c is the bent-back portion 533, the first main body portion 531 of the clamp 50 is composed of a first flat plate portion 55a, a first hinge portion 54a, a second flat plate portion 55b, a second hinge portion 54b, and a third flat plate portion 55c, as shown in Figures 14 and 15. On the other hand, as shown in FIGS. 14 and 15, the second main body portion 532 of the clamp 50 is made up of a fourth flat plate portion 55d, a fourth hinge portion 54d, and a fifth flat plate portion 55e.

[0299] Therefore, as shown in Figure 17(a), the worker deforming the clamp 50 uses the third hinge portion 54c as the folding portion 533 to fold the second main body portion 532 from below to the other side in the width direction Y and overlap it with the first main body portion 531.

[0300] At this time, the worker fits the protrusions 58 of the fourth flat plate portion 55d and the protrusions 58 of the fifth flat plate portion 55e into the fitting holes 57 of the third flat plate portion 55c and the second flat plate portion 55b, respectively.

[0301] Furthermore, as shown in Figure 17(b), the worker folds both end portions of the first flat plate portion 55a cut at the position of the first hinge portion 54a downward, and overlaps them with the central portion of the first flat plate portion 55a while engaging the protrusion portion 58 with the engaging hole 57.

[0302] 14, the clamp 50 is in a state where the second main body portion 532 overlaps the first main body portion 531 and both end portions of the folded-back first main body portion 531 overlap the central portion. At this time, the end faces of both end portions of the folded-back first main body portion 531 on one side in the width direction Y abut against the second flat plate portion 55b.

[0303] In this way, when the clamp 50 has its length in the width direction Y changed, as shown in Figure 15, when the second main body portion 532 overlaps the first main body portion 531, the two insertion holes 52 of the second main body portion 532 adjacent to the bent-back portion 533 and the two insertion holes 52 of the first main body portion 531 adjacent to the bent-back portion 533 are connected in the vertical direction.

[0304] Specifically, in the clamp 50, the fifth insertion hole 52e of the second main body portion 532 is connected to the fourth insertion hole 52d of the first main body portion 531, and the sixth insertion hole 52f of the second main body portion 532 is connected to the third insertion hole 52c of the first main body portion 531.

[0305] Furthermore, for the clamp 50 whose length in the width direction Y has been changed in this manner, the wire harness WH is disposed between the fifth insertion hole 52e and the sixth insertion hole 52f, as shown in Fig. 15. Furthermore, as shown in Fig. 15, the binding band 2 is inserted through the fourth insertion hole 52d and the fifth insertion hole 52e, which are connected to each other, and the third insertion hole 52c and the sixth insertion hole 52f, which are connected to each other.

[0306] The band portion 2a of the binding band 2 is wound around the wire harness WH and is locked by the lock portion 2b, thereby forming a clamp-equipped wire harness 1 in which the wire harness WH is attached to the clamp 50.

[0307] At this time, the first hinge portion 54a overlaps the contact portion between both end portions of the first main body portion 531 and the second main body portion 532, thereby restricting deformation of the clamp main body 53 with the first hinge portion 54a as a fulcrum.

[0308] Furthermore, by overlapping the second hinge portion 54b and the fourth hinge portion 54d, the clamp 50 restricts deformation of the clamp body 53 with the second hinge portion 54b or the fourth hinge portion 54d as a fulcrum.

[0309] As described above, the clamp 50 and clamp-equipped wire harness 1 of Example 5 have a clamp body 53 including a first body portion 531, a second body portion 532, and a bent-back portion 533, and the second body portion 532 is fixed to the first body portion 531 together with the wire harness WH by the cable tie 2, and therefore can achieve the same effects as those of Example 1 described above.

[0310] Furthermore, the clamp body 53 is configured to include a central portion extending in the width direction Y in which the insertion hole 52 is provided, and both end portions connected to the edges of the central portion in the front-rear direction X in a state in which they can be bent toward the lower surface of the central portion. In addition, both end portions of the first body portion 531 are configured to abut against the end surfaces of the second body portion 532 in the width direction Y when they are bent toward the lower surface of the central portion.

[0311] According to this configuration, both end portions of the first main body portion 531 overlap the central portion of the first main body portion 531, so that the clamp 50 can prevent deformation of the central portion of the first main body portion 531 that does not overlap with the second main body portion 532 by means of both end portions of the first main body portion 531.

[0312] Furthermore, the clamp 50 can prevent deformation of the first body portion 531 at the end face position of the second body portion 532 by abutting both end portions of the first body portion 531 against the end face of the second body portion 532. This allows the clamp 50 to reliably ensure the supporting rigidity of the wire harness WH. [Example]

[0313] The clamp-equipped wire harness 1 of Example 6 has a different clamp shape from that of Example 1. The clamp-equipped wire harness 1 of Example 6 will be described with reference to Figs.

[0314] 18A and 18B are explanatory diagrams illustrating the appearance of the clamp-equipped wire harness 1 of Example 6, where FIG. 18A shows an external perspective view of the clamp-equipped wire harness 1 as viewed from above and in the front, and FIG. 18B shows an external perspective view of the clamp-equipped wire harness 1 as viewed from below and in the front. Furthermore, FIG. 19 shows a cross-sectional view taken along the line GG in FIG. Moreover, the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0315] As shown in Figures 18 and 19, the clamp-equipped wire harness 1 of Example 6 includes a wire harness WH that passes through a position spaced apart from the anchor fixing portion 3a on one side in the width direction Y, a clamp 60 that fixes the wire harness WH to the anchor fixing portion 3a, and a cable tie 2 that ties the wire harness WH to the clamp 60.

[0316] As shown in Figures 18 and 19, the clamp 60 of Example 6 is composed of an anchor portion 61 that is engaged with the anchor fixing portion 3a, and a clamp main body 62 that extends from the anchor portion 61 to one side in the width direction Y.

[0317] The anchor portion 61 of the clamp 10 has the same configuration as the anchor portion 11 of the clamp 10 in the first embodiment, and therefore a detailed description thereof will be omitted. On the other hand, as shown in Figures 18 and 19, the clamp body 62 of the clamp 60 is configured to be bent back to the other side in the width direction Y, and includes a first body portion 63 extending from the anchor portion 61 to one side in the width direction Y, a pair of bent-back portions 64 extending from the first body portion 63 to one side in the width direction Y, and a second body portion 65 connected to the first body portion 63 via the bent-back portions 64.

[0318] Specifically, the first main body portion 63 is in the form of a flat plate having a thickness in the up-down direction, and is formed in a generally rectangular shape in plan view that is long in the width direction Y. An anchor portion 61 is provided on the top surface of the first main body portion 63 at an end on the other side in the width direction Y.

[0319] Furthermore, as shown in Figures 18 and 19, the first main body portion 63 has six first insertion holes 63a, through which the binding bands 2 are inserted, formed at positions spaced apart at predetermined intervals in the width direction Y. The six first insertion holes 63a are openings that are elongated in the front-rear direction X and have a generally rectangular shape in a plan view, and are formed at equal intervals in the width direction Y.

[0320] As shown in FIG. 19, the pair of bent-back portions 64 are thinner than the first main body portion 63 and are formed in a flexible band-like body. As shown in Figures 18 and 19, the second main body portion 65 is flat and has approximately the same thickness as the first main body portion 63, and is formed into an approximately rectangular shape in a plan view with a length in the width direction Y that is shorter than that of the first main body portion 63.

[0321] Furthermore, as shown in FIGS. 18 and 19, the second main body portion 65 has two second insertion holes 65a, through which the binding bands 2 are inserted, formed at positions spaced a predetermined distance apart in the width direction Y. These two second insertion holes 65a are openings that are approximately rectangular in plan view and are approximately the same size as the first insertion holes 63a, and are formed at approximately the same distance in the width direction Y between two adjacent first insertion holes 63a.

[0322] As shown in Figures 18 and 19, the clamp 60 having the above-mentioned configuration has its length in the width direction Y changeable by bending the second main body portion 65 to the other side in the width direction Y at the bending portion 64 and overlapping it with the first main body portion 63.

[0323] As shown in Figures 18 and 19, the clamp 60 fixes the wire harness WH, which passes through a position spaced apart from the anchor fixing portion 3a, to the vehicle body 3 by fixing the second main body portion 65 together with the wire harness WH to the first main body portion 63 using a cable tie 2.

[0324] As described above, the clamp 60 and clamp-equipped wire harness 1 of Example 6 have a clamp body 62 that includes a first body portion 63, a second body portion 65, and a bent-back portion 64, and the second body portion 65 is fixed to the first body portion 63 together with the wire harness WH by the cable tie 2, so that the same effects as those of Example 1 described above can be achieved.

[0325] More specifically, by setting the bending position of the bending portion 64 to a position corresponding to the distance between the anchor fixing portion 3a and the wire harness WH, the clamp 60 can change the length of the clamp body 62 including the bending portion 64 to a length corresponding to the distance between the anchor fixing portion 3a and the wire harness WH.

[0326] In correspondence between the configuration of this invention and the above-mentioned embodiment, The predetermined portion of the present invention corresponds to the anchor fixing portion 3a of the embodiment. Similarly, The fixing parts correspond to the anchor parts 11, 21, 31, 41, 51, and 61. The predetermined direction corresponds to one side of the width direction Y, The binding member corresponds to the binding band 2, The direction opposite to the predetermined direction corresponds to the other side of the width direction Y, The first hinge portion corresponds to the first hinge portion 14a and the third hinge portion 14c, The second hinge portion corresponds to the second hinge portion 14b, The main surfaces of the clamp bodies correspond to the lower surfaces of the clamp bodies 23 and 33. The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained.

[0327] For example, in the above-described embodiment, the clamp holds the wire harness WH made up of a plurality of electric wires, but the present invention is not limited to this, and the clamp may hold at least one electric wire. Furthermore, although the wire harness WH is fixed to the vehicle body 3 using a clamp, this is not limited thereto, and the location where the wire harness or at least one electric wire is fixed via the clamp may be any appropriate location.

[0328] In addition, the wire harness WH passes through a position spaced apart in the width direction Y from the anchor fixing portion 3a of the vehicle body 3, which has a thickness in the vertical direction, but is not limited to this, and the wire harness WH may pass through a position spaced apart in the vertical direction from the anchor fixing portion 3a. In this case, the clamp has a thickness in the vertical direction, and an L-shaped clamp body is formed by a base portion where the anchor portion is provided and an extension portion extending in the vertical direction from the base portion.

[0329] Furthermore, although one wire harness WH is fixed to the clamp with one cable tie 2, the present invention is not limited to this, and one cable tie 2 may be used to fix a plurality of wire harnesses WH to the clamp.

[0330] Furthermore, in the clamps of Examples 1 to 6, the anchor portion has a generally oblong shape in plan view that is long in the width direction Y, but this is not limited to this, and the anchor portion may have any appropriate shape, such as a generally circular shape in plan view, as long as it can be engaged with the anchor fixing portion 3a.

[0331] Furthermore, in the clamps of Examples 1 to 6, the number and positions of the hinge portions, as well as the number and positions of the insertion holes, are not limited to those of the above-described embodiments, and may be any appropriate number and position as long as the two insertion holes of the first main body portion and the two insertion holes of the second main body portion can communicate with each other when the second main body portion is overlapped on the first main body portion.

[0332] Furthermore, in the clamp-equipped wire harnesses 1 of Examples 1 to 6, the cable tie 2 is inserted into two insertion holes adjacent to each other in the width direction Y, but this is not limited to this, and the cable tie 2 may be inserted into insertion holes spaced apart in the width direction Y.

[0333] For example, in Example 1, if the second hinge portion 14b is the bent-back portion 133, the cable tie 2 may be configured to be inserted through the connected third insertion hole 12c and fourth insertion hole 12de, and the connected first insertion hole 12a and sixth insertion hole 12f.

[0334] In addition, in the first and fourth embodiments, either one of the overlapping first and second main body portions may be provided with a locking portion that protrudes from one toward the other and is locked to the other. Furthermore, in the above-described Examples 2 and 3, clamps 20 and 30 are provided with locking portions 26 and 37 on the underside of clamp bodies 23 and 33, respectively, but this is not limited to this, and clamps may also be provided with locking portions on the front and rear surfaces of the clamp body.

[0335] For example, as shown in FIG. 20 which shows an explanatory diagram illustrating a clamp-equipped wire harness 1 in another embodiment, and FIG. 21 which shows an explanatory diagram illustrating a clamp 70 in another embodiment, the clamp 70 may have locking portions 72 provided at both ends of the clamp body 71 in the front-to-rear direction X.

[0336] In the fourth embodiment described above, a notch may be provided at the upper end of the separation portion 46b of the side wall portion 46 to make separation even easier. In the fourth embodiment, the separation portion 46b is formed by thinning the side wall portion 46, but this is not limitative, and for example, a notch provided in the side wall portion 46 may be used as the separation portion.

[0337] Furthermore, in the above-described first to fifth embodiments, the hinge portion is formed by thinning the wall, but this is not limitative, and the hinge portion may be formed of, for example, a shaft body and a shaft cylinder. Alternatively, as shown in Figure 22, which is an explanatory diagram illustrating a clamp 80 in another embodiment, the clamp 80 may have a clamp body 82 that extends from an anchor portion 81 to one side in the width direction Y and does not have a hinge portion.

[0338] 22, the clamp body 82 of the clamp 80 is formed so that the longitudinal cross section along the front-rear direction X has a generally arcuate cross section that protrudes downward. This prevents the clamp 80 from being flexed and deformed by the weight of the wire harness WH. Furthermore, as shown in FIG. 22, the clamp body 82 is formed with a plurality of insertion holes 83 at positions spaced apart by a predetermined distance in the width direction Y, through which the binding bands 2 are inserted.

[0339] As shown in Figure 23, which is an explanatory diagram illustrating a clamp-equipped wire harness 1 in another embodiment, the clamp 80 wraps the clamp body 82 around the wire harness WH and holds the wire harness WH with a cable tie 2 inserted into the insertion hole 83 of the clamp body 82.

[0340] That is, the clamp 80 has a configuration in which a portion extending from the anchor portion 81 to one side in the width direction Y is a first main body portion 821, a portion that is wrapped around the wire harness WH and bends back the clamp main body 82 is a bent-back portion 822, and a portion from the bent-back portion 822 to the tip is a second main body portion 823. Even with this configuration, the clamp 80 can achieve the same effects as in the first embodiment described above. [Explanation of symbols]
