[0004] In fixing a wiring component, temporary fixing portions provided on a wiring component holding portion are temporarily fixed to the vehicle body at multiple locations along the wiring path, and then the fixing portions are permanently fixed (screw-fastened) to the vehicle body at multiple other locations. For example, the temporary fixing portions are temporarily fixed to the vehicle body by inserting clips provided on the temporary fixing portions into through holes in the vehicle body or by inserting stud bolts of the vehicle body into through holes provided on the temporary fixing portions. Then, the fixing portions are fixed to the vehicle body by screwing a male screw member passed through the through hole into a female screw portion of the vehicle body. In such conventional technology, the temporary fixing work at the temporary fixing portions and the fixing work at the fixing portions must be performed separately in different locations.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A clamp, a clamp mounting structure, and a protector according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] [Embodiment] One embodiment of a clamp, a clamp mounting structure, and a protector according to the present invention will be described with reference to FIGS.

[0013] Reference numeral 1 in FIGS. 1 to 4 indicates a clamp mounting structure of this embodiment.

[0014] The clamp mounting structure 1 comprises a clamp installation section 10 provided on the vehicle body B, a clamp 20 installed on the clamp installation section 10, and a clamp fixture 30 that fixes the clamp 20 to the clamp installation section 10 (Figures 1 to 4).

[0015] This clamp mounting structure 1 secures a component to which the clamp 20 is attached to the vehicle body B by fixing the clamp 20 to a clamp installation portion 10 of the vehicle body B. Here, an example of the component is a wiring component (not shown), such as a wire harness or a bus bar, which is routed and fixed to the vehicle body B. The wiring component is held in a wiring component holding portion (not shown) on the routing path and is fixed to the vehicle body B via the clamp 20 connected to the wiring component holding portion. To give a specific example, a protector (not shown) is attached to the wiring component to protect it. The protector has a protector main body as a wiring component holding portion that holds and protects the wiring component inside, and a clamp 20 connected to the protector main body. The protector secures the wiring component held and protected by the protector main body to the vehicle body B by fixing the clamp 20 to the clamp installation portion 10 of the vehicle body B with a clamp fixture 30. The clamp mounting structure 1 can fix the clamp 20 to the clamp installation portion 10 to temporarily fasten the wiring component that has been installed in the vehicle body B to the vehicle body B (hereinafter referred to as "temporary fixing"), and can fix the clamp 20 to the clamp installation portion 10 to fasten the wiring component in the temporarily fastened state to the vehicle body B (hereinafter referred to as "full fixing").

[0016] The clamp installation section 10 is configured to perform both temporary and final fixing of the clamp 20. The clamp installation section 10 includes a fixture holding section 11 into which the fixing section 31 of the clamp fixture 30 is inserted and held, an installation surface 12 provided on the periphery of the fixture holding section 11 and on which the clamp 20 is installed, at least one standing wall 13 erected from the installation surface 12, and a locking section 14 protruding from the standing wall 13 (FIGS. 1 to 5). In the clamp installation section 10, the clamp 20 is temporarily fixed on the installation surface 12 by the standing wall 13 and the locking section 14, and the clamp fixture 30 and the fixture holding section 11 finally fix the clamp 20 on the installation surface 12.

[0017] The clamp installation part 10 shown here has a boss part 15 formed in a cylindrical boss shape, with the interior of the cylinder serving as a fixture holding part 11 and the tip surface serving as an installation surface 12 (FIGS. 1 to 5). The boss part 15 of this embodiment is formed in a boss shape with a coaxial cylindrical through hole or groove in a truncated cone, with the through hole or groove serving as the fixture holding part 11 and the annular flat surface at the tip serving as the installation surface 12.

[0018] This boss portion 15 is provided in a protruding state on the outer wall surface of the vehicle body B (FIG. 1). For example, the boss portion 15 may be a part of the vehicle body B that is press-molded together with the vehicle body B, or may be a separate part molded from a metal material that is integrated with the vehicle body B by welding or the like.

[0019] The standing wall 13 is erected from the outer periphery of the installation surface 12 (FIGS. 1 to 5). For example, when only one standing wall 13 is provided, a coaxial C-shaped ring-shaped standing wall 13 is erected from the outer periphery of the annular installation surface 12. The clamp installation section 10 shown here has two arc-shaped standing walls 13 (FIGS. 1 to 5). These two standing walls 13 are arranged at equal intervals in the circumferential direction of the annular installation surface 12. Therefore, two adjacent standing walls 13 in the circumferential direction are arranged with equal gaps between their respective ends in the circumferential direction.

[0020] The standing wall 13 has a cantilever shape with the fixed end facing the installation surface 12, and a claw-shaped locking portion 14 protrudes from the inner circumferential surface of its free end (FIGS. 1 to 4). This locking portion 14 is disposed with a gap between it and the installation surface 12, and locks a clamp 20 inserted into the gap, temporarily fixing the clamp 20 on the installation surface 12. The locking portion 14 shown here is formed on the inner circumferential surface of the free end of the standing wall 13 from one end to the other in the circumferential direction.

[0021] The clamp 20 is installed on the installation surface 12 and includes a clamp body 21 that is fixed to the installation surface 12 by a clamp fixture 30 that is inserted into and held by a fixture holding portion 11 (FIGS. 1 to 4). The clamp body 21 shown here is molded from a synthetic resin material.

[0022] The clamp body 21 has a vehicle body fixing portion 41 that is assembled and fixed to the vehicle body B side (FIGS. 1 to 4). This vehicle body fixing portion 41 is formed with a fixing tool insertion hole 41a through which the fixing portion 31 of the clamp fixture 30 is inserted. The vehicle body fixing portion 41 is installed so that the installation surface 41b around the fixing tool insertion hole 41a is aligned with the installation position on the installation surface 12. When the fixing portion 31 of the clamp fixture 30 is passed through the fixing tool insertion hole 41a at the installation position and inserted into and held by the fixing tool holding portion 11 of the clamp installation part 10, the vehicle body fixing portion 41 is sandwiched between the clamping portion 32 of the clamp fixture 30 and the installation surface 12 and fixed (i.e., permanently fixed) to the installation surface 12 (FIGS. 1 to 3).

[0023] The vehicle body fixing part 41 shown here is formed in an annular shape with both axial ends being flat, with its through-hole serving as a fastener insertion hole 41a and one of the flat annular surfaces serving as an installation surface 41b (Fig. 4). This vehicle body fixing part 41 is installed coaxially on the annular installation surface 12. Note that the vehicle body fixing part 41 in the figure has a two-layer structure in which two annular parts are concentrically arranged with a gap between them. Therefore, the inside of the annular part of the inner layer of this vehicle body fixing part 41 serves as the fastener insertion hole 41a, and one of the two annular flat surfaces on the same plane serves as the installation surface 41b.

[0024] Here, the clamp fixture 30 has a fixing portion 31 which is a male screw portion and a clamping portion 32 which is a male screw member with a head portion. The fixture holding portion 11 has a female screw portion into which the male screw portion (fixing portion 31) is screwed. In other words, the vehicle body fixing portion 41 is screwed and fixed (i.e., permanently fixed) to the installation surface 12 by the clamp fixture 30 and the fixture holding portion 11. As described above, the clamp body 21 is molded from a synthetic resin material. Therefore, the clamp 20 of this embodiment has a collar member 22 which is fitted into the fixture insertion hole 41a and into which the male screw portion (fixing portion 31) is inserted (FIGS. 3 and 4).

[0025] The collar member 22 is formed into a cylindrical shape from a metal material. One end of the collar member 22 in the cylindrical axis direction protrudes from one annular flat surface of the vehicle body fixing portion 41, and the other end of the collar member 22 in the cylindrical axis direction protrudes from the other annular flat surface of the vehicle body fixing portion 41. As a result, when the vehicle body fixing portion 41 is in the installation position, the collar member 22 is clamped between the head (clamping portion 32) of the clamp fixing device 30 passed through the inside and the installation surface 12 by screwing the male thread portion (fixing portion 31) of the clamp fixing device 30 into the female thread portion of the fixture holding portion 11. In other words, the vehicle body fixing portion 41 is screwed (mainly fixed) to the installation surface 12 via the collar member 22 that is integrated with the collar member 22.

[0026] The clamp body 21 further has multiple cantilever-shaped flexible portions 42 that protrude from the installation surface 41b of the vehicle body fixing portion 41, cover the outer peripheral surface 41c of the vehicle body fixing portion 41 (the outer peripheral surface of the outer annular portion) with an inner wall surface 42a, and change the distance between the outer peripheral surface 41c and the inner wall surface 42a by bending (FIGS. 1 to 4). When the vehicle body fixing portion 41 is in the installation position, the outer wall surface 42b of the flexible portions 42 is covered by the standing wall 13 of the clamp installation portion 10, and the free ends of the flexible portions 42 are engaged with the engaging portions 14 of the clamp installation portion 10 to prevent movement of the vehicle body fixing portion 41 at the installation position away from the installation surface 12 in the axial direction of the fastener insertion hole 41a (FIGS. 1 to 3). This temporarily fixes the vehicle body fixing portion 41 to the installation surface 12.

[0027] The flexible portion 42 shown here protrudes from one flat surface (installation surface 41b) of the vehicle body fixing portion 41 toward the other flat surface, and is tilted relative to the axis of the fixing tool insertion hole 41a so that the distance between the outer peripheral surface 41c and the inner wall surface 42a increases as the distance from the one flat surface (installation surface 41b) approaches the other flat surface. The clamp body 21 shown here has two flexible portions 42 formed as arc-shaped pieces. The two flexible portions 42 are arranged at equal intervals in the circumferential direction of the installation surface 41b. Therefore, two adjacent flexible portions 42 are arranged with equal gaps between their respective one ends and other ends in the circumferential direction.

[0028] A combination of a standing wall 13 and a locking portion 14 is provided for each flexible portion 42 (FIGS. 1 and 4). Here, one standing wall 13 and one flexible portion 42 are arranged opposite each other, and the other standing wall 13 and the other flexible portion 42 are arranged opposite each other, so that the free end of one flexible portion 42 is locked with the locking portion 14 at the free end of one standing wall 13, and the free end of the other flexible portion 42 is locked with the locking portion 14 at the free end of the other standing wall 13.

[0029] In clamp main body 21, when clamp installation part 10 is installed on installation surface 12, locking part 14 of clamp installation part 10 abuts against outer wall surface 42b of flexible part 42, and the pressing force from locking part 14 bends flexible part 42 toward outer peripheral surface 41c of vehicle body fixing part 41. When vehicle body fixing part 41 reaches an installation position on installation surface 12, the free end of flexible part 42 climbs over locking part 14, and thus the free end enters the gap between locking part 14 and installation surface 12 while releasing its own bending. As a result, in clamp main body 21, when vehicle body fixing part 41 in the installation position attempts to move away from installation surface 12 in the hole axial direction of fastener insertion hole 41a, the free end of flexible part 42 abuts against locking part 14 and is locked, so that vehicle body fixing part 41 can be maintained in the installation position on installation surface 12 (i.e., temporarily fixed).

[0030] The clamp body 21 further has a connecting portion 43 (FIGS. 1 to 4) that connects the vehicle body fixing portion 41 to the wiring component holding portion (protector body). The connecting portion 43 is engaged with the vertical wall 13 to prevent movement around the axis of the fixing tool insertion hole 41a in the vehicle body fixing portion 41 when the vehicle body fixing portion 41 is installed.

[0031] The connecting portion 43 shown here has a piece 43a that protrudes from the outer peripheral surface 41c of the vehicle body fixing portion 41 (FIGS. 1, 2, and 4). In the clamp body 21, the piece 43a protrudes from one of the gaps formed by two adjacent flexible portions 42.

[0032] For example, in the case of the C-shaped annular standing wall 13 shown above, when the vehicle body fixing part 41 is in the installation position, the pieces 43a are placed in the gap between both ends of the circumferential direction of the standing wall 13, and the pieces 43a are engaged with both ends of the standing wall 13. This makes it possible to restrict movement of the clamp body 21 around the axis of the fastener insertion hole 41a in the vehicle body fixing part 41 in the installation position, and therefore it is possible to maintain (i.e., temporarily fix) the vehicle body fixing part 41 in the installation position on the installation surface 12.

[0033] As described above, two circumferentially adjacent standing walls 13 are provided. Therefore, in this example, the piece 43a is disposed in one of the gaps formed by the two adjacent standing walls 13 (FIGS. 1, 2, and 4). That is, the clamp installation portion 10 has two adjacent standing walls 13 spaced apart by a gap in which the connecting portion 43 is disposed. The two adjacent standing walls 13 each have a piece 43a of the connecting portion 43 engaged with one of the adjacent standing walls 13, thereby restricting movement around the axis of the fastener insertion hole 41a in the vehicle body fixing portion 41 at the installation position. This allows the clamp main body 21 to maintain (i.e., temporarily fix) the vehicle body fixing portion 41 in the installation position on the installation surface 12.

[0034] As described above, the clamp 20, clamp mounting structure 1, and protector of this embodiment can be installed and temporarily fixed on the installation surface 12 of the clamp installation section 10 simply by pushing the clamp 20 into the clamp installation section 10. In other words, the clamp 20, clamp mounting structure 1, and protector of this embodiment can temporarily fix the clamp 20 to the installation surface 12 of the clamp installation section 10 simply by installing the clamp 20 on the installation surface 12. The clamp 20, clamp mounting structure 1, and protector of this embodiment can then finally fix the clamp 20 in a temporarily fixed state to the installation surface 12 of the clamp installation section 10 simply by attaching the clamp fixture 30 to the fixture holding section 11 of the clamp installation section 10. In this way, the clamp 20, clamp mounting structure 1, and protector of this embodiment allow the clamp 20 to be easily temporarily and finally fixed in the same place.

[0035] Incidentally, the clamp installation portion 10 of this embodiment has been exemplified as having the boss portion 15 described above, but it may be configured without such a boss portion 15. For example, the installation surface 12 is provided on the outer wall surface of the vehicle body B. In this case, the fixing tool holding portion 11 is formed on the vehicle body B.

[0036] [Variation 1] 6 to 8, reference numeral 2 indicates a clamp mounting structure of this modified example. In the clamp mounting structure 2 of this modified example, the clamp installation section 10 and the clamp 20 in the clamp mounting structure 1 of the above-described embodiment are replaced with the clamp installation section 110 and the clamp 120 described below. In the clamp mounting structure 2 of this modified example, the same parts as those in the clamp mounting structure 1 of the embodiment are given the same reference numerals, and their description will be omitted.

[0037] The clamp installation section 110 of this modified example is the clamp installation section 10 of the embodiment, in which the number of combinations of the standing walls 13 and the locking sections 14 is changed.

[0038] The clamp installation portion 110 of this modified example has three arc-shaped standing walls 113 (FIGS. 6 to 8). These three standing walls 113 are arranged at equal intervals in the circumferential direction of the annular installation surface 12. Therefore, among all the standing walls 113, two adjacent standing walls 113 in the circumferential direction are arranged with equal gaps between their respective ends in the circumferential direction. The locking portion 114 of this modified example is a claw-shaped portion similar to the locking portion 14 of the embodiment, and is formed on the inner circumferential surface of the free end of the standing wall 113 from one end to the other in the circumferential direction (FIGS. 6 to 8).

[0039] A clamp 120 of this modification is obtained by changing the number of flexible portions 42 of clamp body 21 in clamp 20 of the embodiment in accordance with the number of combinations of standing walls 113 and locking portions 114 in this modification.

[0040] The clamp body 121 of this modified example is provided with three flexible portions 142 formed as arc-shaped pieces corresponding to the three combinations of the standing walls 113 and the locking portions 114 (FIGS. 6 to 8). The three flexible portions 142 are arranged at equal intervals in the circumferential direction of the installation surface 41b. Therefore, in all of the flexible portions 142, two adjacent flexible portions 142 in the circumferential direction are arranged with equal gaps between their respective one ends and between their respective other ends in the circumferential direction.

[0041] The clamp 120, clamp mounting structure 2, and protector of this modified example are obtained by modifying the clamp 20, clamp mounting structure 1, and protector of the embodiment in the above manner. Therefore, the clamp 120, clamp mounting structure 2, and protector of this modified example can obtain the same effects as the clamp 20, clamp mounting structure 1, and protector of the embodiment.

[0042] [Variation 2] 9 to 11 designates a clamp mounting structure of this modified example. In clamp mounting structure 3 of this modified example, the clamp installation portion 10 and clamp 20 in clamp mounting structure 1 of the above-described embodiment are replaced with clamp installation portion 210 and clamp 220 described below, and multiple pairs of fastener holding portions 11 and fastener insertion holes 41a are provided. In clamp mounting structure 3 of this modified example, the same parts as in clamp mounting structure 1 of the embodiment are assigned the same reference numerals as in the embodiment, and their description will be omitted.

[0043] The clamp installation section 210 of this modified example is the clamp installation section 10 of the embodiment in which the shape of the boss portion 15 is changed, and accordingly the shape of the installation surface 12 and the number of fastener holding portions 11 are changed.

[0044] Boss portion 215 of this modified example has an elliptical cross section and is formed in a boss shape with two cylindrical through holes or grooves with parallel axes (FIGS. 9 to 12). In this boss portion 215, the two through holes or grooves each serve as fastener holding portions 11, and the flat surface of the ellipse at the tip serves as installation surface 212 (FIGS. 9 to 12). Here, fastener holding portions 11 are formed at one end and the other end of the longitudinal direction of elliptical installation surface 212, with their axes parallel to each other.

[0045] The clamp installation portion 210 of this modified example is provided with two arc-shaped standing walls 213 (FIGS. 9 to 12). The two standing walls 213 are disposed at one end and the other end of the longitudinal direction of the oval installation surface 212, at equal intervals in the circumferential direction of the installation surface 212. Therefore, two adjacent standing walls 213 in the circumferential direction are disposed with equal gaps between their respective one ends and their respective other ends in the circumferential direction. The locking portion 214 of this modified example is a claw-shaped portion similar to the locking portion 14 of the embodiment, and is formed on the inner circumferential surface of the free end of the standing wall 213 from one end to the other end in the circumferential direction (FIGS. 9 to 12).

[0046] In the clamp 220 of this modified example, the shape of the vehicle body fixing portion 41 of the clamp main body 21 in the clamp 20 of the embodiment is changed, and accordingly the number of fixing tool insertion holes 41a is changed.

[0047] The clamp body 221 of this modified example has a vehicle body fixing portion 241 with an elliptical cross section and two cylindrical through-holes with parallel axes (FIGS. 9 to 11). In this vehicle body fixing portion 241, the two through-holes are each formed as a fastener insertion hole 41a, and a collar member 22 is fitted into each of the fastener insertion holes 41a (FIG. 11). In addition, one of the elliptical flat surfaces of this vehicle body fixing portion 241 is formed as an installation surface 241b (FIG. 11). Here, the fastener insertion holes 41a are formed at one end and the other end of the longitudinal direction of the elliptical installation surface 241b, with their axes parallel to each other.

[0048] The clamp body 221 of this modified example is provided with two flexible portions 242 formed as arc-shaped pieces to match the two combinations of the standing wall 213 and the locking portion 214 (FIGS. 9 to 11). The two flexible portions 242 are arranged at one end and the other end of the longitudinal direction of the oval installation surface 241b, at equal intervals in the circumferential direction of the installation surface 241b. Therefore, two adjacent flexible portions 242 in the circumferential direction are arranged with equal gaps between their one ends and their other ends in the circumferential direction. The flexible portions 242 change the gap between their inner wall surface 242a and the outer peripheral surface 241c of the vehicle body fixing portion 241 by bending and deforming. The outer wall surface 242b of the flexible portion 242 is covered by the standing wall 213, and its free end is locked by the locking portion 214.

[0049] As with the clamp body 21 of the embodiment, the clamp body 221 of this modified example may have its connecting portion 43 engaged with the vertical wall 213, thereby restricting movement of the fastener insertion hole 41 a in the vehicle body fixing portion 241 in the installed position about the hole axis thereof. Furthermore, the clamp body 221 of this modified example may have one flexible portion 242 engaged with one vertical wall 213 in the circumferential direction thereof, and the other flexible portion 242 engaged with the other vertical wall 213 in the circumferential direction thereof, thereby restricting movement of the fastener insertion hole 41 a in the vehicle body fixing portion 241 in the installed position about the hole axis thereof.

[0050] The clamp 220, clamp mounting structure 3, and protector of this modified example are obtained by modifying the clamp 20, clamp mounting structure 1, and protector of the embodiment in the above manner. Therefore, the clamp 220, clamp mounting structure 3, and protector of this modified example can obtain the same effects as the clamp 20, clamp mounting structure 1, and protector of the embodiment.

[0051] [Variation 3] 13 to 15 designates a clamp mounting structure of this modified example. In clamp mounting structure 4 of this modified example, clamp installation section 210 and clamp 220 in clamp mounting structure 3 of modified example 2 described above are replaced with clamp installation section 310 and clamp 320 described below. In clamp mounting structure 4 of this modified example, parts that are the same as those in clamp mounting structure 3 of modified example 2 are given the same reference numerals as in the embodiment, and descriptions thereof will be omitted.

[0052] The clamp installation section 310 of this modification is the clamp installation section 210 of the second modification, except that the number of combinations of the standing walls 213 and the locking sections 214 is changed.

[0053] The clamp installation section 310 of this modified example has two arc-shaped upright walls 313A and one linear upright wall 313B (FIGS. 13 to 15). The three upright walls 313A, 313B are spaced apart in the circumferential direction of the oval installation surface 212. Two circumferentially adjacent upright walls 313A are located at one end and the other end of the longitudinal direction of the oval installation surface 212, close to one side located in the short direction. In the connecting section 43 of the clamp main body 321 (described later), a piece 43a is located in the gap between the two upright walls 313A. The upright wall 313B is located on the other side located in the short direction of the oval installation surface 212. An arc-shaped locking portion 314A is formed on the inner peripheral surface of the free end of the standing wall 313A from one end to the other in the circumferential direction (FIGS. 13 to 15). Also, a linear locking portion 314B is formed on the inner peripheral surface of the free end of the standing wall 313B from one end to the other in the circumferential direction (FIGS. 13 to 15).

[0054] Clamp 320 of this modification is obtained by changing the number and shape of flexible portions 242 of clamp body 221 in clamp 220 of modification 2 to match standing walls 313A and 313B of this modification.

[0055] The clamp body 321 of this modification has two flexible portions 342A formed as arc-shaped pieces corresponding to two combinations of the standing wall 313A and the locking portion 314A, and one flexible portion 342B formed as a linear piece corresponding to one combination of the standing wall 313B and the locking portion 314B (FIGS. 13 to 15). The three flexible portions 342A, 342B are spaced apart from one another in the circumferential direction of the elliptical mounting surface 241b. Two adjacent flexible portions 342A in the circumferential direction are positioned at one end and the other in the longitudinal direction of the elliptical mounting surface 241b, close to one side in the lateral direction. In the connecting portion 43, a piece 43a is positioned in the gap between the two flexible portions 342A. Here, by engaging one portion 43a of this connecting portion 43 with one standing wall 313A and the other standing wall 313A, movement around the axis of the fixing tool insertion hole 41a in the vehicle body fixing portion 241 at the installation position is suppressed. In addition, the flexible portion 342B is disposed on the other side located in the short direction of the oval installation surface 241b.

[0056] The clamp 320, clamp mounting structure 4, and protector of this modified example are obtained by modifying the clamp 220, clamp mounting structure 3, and protector of modified example 2. Therefore, the clamp 320, clamp mounting structure 4, and protector of this modified example can achieve the same effects as the clamp 220, clamp mounting structure 3, and protector of the embodiment.

[0057] [Variation 4] Reference numeral 5 in Figure 16 indicates the clamp mounting structure of this modified example. In clamp mounting structure 5 of this modified example, the clamp installation section 10, clamp 20, and clamp fixture 30 in clamp mounting structure 1 of the previously described embodiment are replaced with clamp installation section 410, clamp 420, and clamp fixture 430 described below. In clamp mounting structure 5 of this modified example, the same parts as in clamp mounting structure 1 of the embodiment are given the same reference numerals, and their description will be omitted. Note that, here, changes to clamp mounting structure 1 of the embodiment will be described as an example, but these changes can also be applied to clamp mounting structures 2, 3, and 4 of the previously described modifications 1 to 3.

[0058] In the clamp mounting structure 5 of this modified example, the structure required for permanently fixing the clamp 420 is changed as follows compared to the clamp mounting structure 1 of the embodiment in which the clamp 20 is permanently fixed by a screw fastening structure.

[0059] Clamp installation section 410 of this modified example is obtained by changing fixture holding section 11 in clamp installation section 10 of the embodiment to fixture holding section 411 (FIG. 16). Fixture holding section 411 is a cylindrical through-hole or groove that resembles fixture holding section 11 of the embodiment with the female screw section removed.

[0060] The clamp 420 of this modified example corresponds to the clamp 20 of the embodiment in which the collar member 22 is removed from the fastener insertion hole 41a of the clamp body 21.

[0061] Clamp fixture 430 of this modified example is an elastic member with fixing portion 431 as its shaft (FIG. 16). Fixing portion 431 is fitted into fixing device holding portion 411 in a contracted state, and a reaction force resulting from elastic deformation acts on the inner circumferential surface of fixing device holding portion 411, thereby being held by fixing device holding portion 411. Therefore, fixing portion 431 shown here is formed in a cylindrical shape to match the shape of fixing device holding portion 411.

[0062] In the clamp mounting structure 5 of this modified example, the vehicle body fixing portion 41 of the clamp main body 21 is installed on the installation surface 12 of the clamp installation portion 410, and at this installation position, the fixing portion 431 of the clamp fixture 430 is passed through the fixture insertion hole 41a of the vehicle body fixing portion 41 and inserted into and held by the fixture holding portion 411 of the clamp installation portion 410. At this time, in the clamp mounting structure 5 of this modified example, the vehicle body fixing portion 41 is sandwiched between the clamping portion 432 ( FIG. 16 ) of the clamp fixture 430 and the installation surface 12 and fixed to the installation surface 12 (i.e., permanently fixed).

[0063] The clamp 420, clamp mounting structure 5, and protector of this modified example are obtained by modifying the clamp 20, clamp mounting structure 1, and protector of the embodiment in the above manner. Therefore, the clamp 420, clamp mounting structure 5, and protector of this modified example can obtain the same effects as the clamp 20, clamp mounting structure 1, and protector of the embodiment.
