Description

Technical Field

[0001] The present disclosure relates to a wire harness.

Background Art

[0002] For example, the wire harness of Patent Document 1 includes a fixing member that fixes a wire member to a vehicle body. The fixing member has a holding portion that holds the wire member and a bolt fixing portion that is fixed to a bolt provided on the vehicle body. The bolt fixing portion has a locking piece that locks in the axial direction with respect to the threaded portion of the bolt. At least a pair of locking pieces are provided so as to sandwich the bolt in a direction perpendicular to the axis. When assembling the fixing member to the bolt, the bolt is inserted into the fixing member. At this time, each locking piece bends in a direction in which they separate from each other by being pushed by the bolt. Then, each locking piece is biased toward the bolt by its own elasticity and locks to the threaded portion of the bolt.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Due to a shift in the path of the wire harness or the like, the position of the fixing member with respect to the bolt on the vehicle side may shift in the direction in which the pair of locking pieces face each other. In this case, since the bolt is in a positional relationship approaching one of the pair of locking pieces, the locking state between the locking piece and the bolt may become unstable or unable to be locked. As a result, the fixing member cannot be fixed to the bolt, or even if the fixing member can be fixed to the bolt, there is a risk that the locking is unstable and the fixing member may fall off from the bolt.

[0005] An object of the present disclosure is to provide a wire harness capable of stabilizing the fixing of a fixing member to a bolt.

Means for Solving the Problem

[0006] The wire harness of the present disclosure is a wire harness including a wire member having an electric wire and a fixing member for fixing the wire member to an object to be attached. The fixing member has a bolt fixing portion fixed to a bolt of the object to be attached and a holding portion for holding the wire member. The bolt fixing portion has a fixing portion main body having an insertion hole through which the bolt is inserted, and a locking ring fixed to the bolt by being axially locked to a threaded portion of the bolt disposed inside the insertion hole. The insertion hole has a movement restricting portion for restricting relative movement of the locking ring in the axial direction of the bolt, and the locking ring is configured to be movable in a direction orthogonal to the axis of the bolt inside the insertion hole.

Advantageous Effects of the Invention

[0007] According to the wire harness of the present disclosure, it is possible to stabilize the fixing of the fixing member to the bolt.

Modes for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure is [1] A wire harness including a wire member having a wire and a fixing member for fixing the wire member to an object to be attached, wherein the fixing member has a bolt fixing portion fixed to a bolt of the object to be attached and a holding portion for holding the wire member, the bolt fixing portion having a fixing portion main body having an insertion hole through which the bolt is inserted and a locking ring fixed to the bolt by being axially locked to a threaded portion of the bolt disposed inside the insertion hole, the insertion hole having a movement restricting portion for restricting relative movement of the locking ring in the axial direction of the bolt, and the locking ring being configured to be movable in a direction orthogonal to the axis of the bolt inside the insertion hole.

[0010] According to this configuration, since the relative movement of the locking ring fixed to the bolt in the axial direction of the bolt is restricted by the movement restricting portion, the state where the bolt is inserted into the insertion hole can be maintained. And the locking ring is configured to be movable in a direction orthogonal to the axis of the bolt inside the insertion hole. That is, relative movement of the bolt and the locking ring and the fixing member in the direction orthogonal to the axis is allowed. For this reason, for example, even when the position of the fixing member with respect to the bolt is displaced in the direction orthogonal to the axis of the bolt due to a deviation in the path of the wire harness or the like, it is possible to stabilize the fixing of the fixing member with respect to the bolt.

[0011] [2] The locking ring is configured to be movable inside the insertion hole in both a first direction orthogonal to the axial direction of the bolt and a second direction orthogonal to each of the axial direction of the bolt and the first direction.

[0012] According to this configuration, it is possible to allow displacement between the bolt and the fixing member in the first direction and the second direction orthogonal to the axial direction of the bolt. Therefore, it is possible to further stabilize the fixing of the fixing member with respect to the bolt.

[0013] [3] The fixing portion main body has a ring insertion hole communicating with the insertion hole and into which the locking ring can be inserted. According to this configuration, it becomes possible to insert the locking ring from the ring insertion hole into the insertion hole and fix it to the bolt in the insertion hole.

[0014] [4] The locking ring has a C shape when viewed from the axial direction of the bolt. According to this configuration, it becomes possible to facilitate the assembly of the locking ring to the bolt. [5] An outer member that covers the outer circumference of the wire member and a path restricting member that is attached to the outer circumference of the outer member and restricts the path of the outer member are provided. The path restricting member has an insertion port that opens in a direction orthogonal to the length direction of the path restricting member and extends over the entire length direction of the path restricting member. According to this configuration, in a wire harness provided with a path restricting member, it becomes possible to suppress damage to the biasing portion of the bolt fixing portion.

[0015] [6] The holding portion holds the path restricting member in a manner that covers the entire circumference of the path restricting member. The holding portion has a protrusion that protrudes toward the inner peripheral side, and the protrusion is located inside the insertion port. According to this configuration, it becomes possible to restrict the relative rotation of the path restricting member with respect to the holding portion by the protrusion of the holding portion.

[0016] [Details of the Embodiment of the Present Disclosure] A specific example of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be exaggerated or simplified. Also, the dimensional ratios of each part may be different in each drawing. Also, the term "orthogonal" in this specification includes not only the case of strict orthogonality but also the case of approximate orthogonality within the range where the actions and effects in the present embodiment are exhibited.

[0017] In addition, the term "opposite" in this specification means that surfaces or members are in a front-facing position relative to each other, including not only the case where they are completely in a front-facing position but also the case where they are partially in a front-facing position. Further, the term "opposite" in this specification includes both the case where there is a member other than the two parts intervening between the two parts and the case where nothing intervenes between the two parts.

[0018] (Overall Configuration of Wire Harness 10) The wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle, for example. The wire harness 10 electrically connects two or more in-vehicle devices. The in-vehicle devices are electrical devices mounted on the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 installed at the front part of the vehicle V and a high-voltage battery M2 installed behind the inverter M1 in the vehicle V. The wire harness 10 is formed in a long shape so as to extend in the front-rear direction of the vehicle V, for example. The wire harness 10 is routed in the vehicle V such that an intermediate part in the length direction of the wire harness 10 passes through the outside of the vehicle body such as under the floor of the vehicle V, for example.

[0019] The inverter M1 is connected to a motor (not shown) for driving wheels, which is a power source for vehicle travel, for example. The inverter M1 generates AC power from the DC power of the high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is a battery capable of supplying a voltage of several hundred volts, for example.

[0020] The wire harness 10 has a wire harness main body 11. The wire harness main body 11 has a wire member 20 and a cylindrical exterior member 30 that covers the outer periphery of the wire member 20. The wire harness 10 has connectors C1 and C2 attached to both ends of the wire member 20. One end portion in the length direction of the wire member 20 is connected to the inverter M1 via the connector C1, and the other end portion in the length direction of the wire member 20 is connected to the high-voltage battery M2 via the connector C2.

[0021] (Configuration of Wire Member 20) As shown in FIGS. 2 and 3, the wire member 20 includes, for example, one or a plurality of wires. In this embodiment, the wire member 20 includes two wires 21 and a braided member 25 that collectively surrounds the outer peripheries of the plurality of wires 21.

[0022] As shown in FIG. 2, each wire 21 is a coated wire having a conductive core wire 22 and an insulating coating 23 that surrounds the outer periphery of the core wire 22 and has insulating properties. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage and large current. Each wire 21 may be, for example, a non-shielded wire that does not have an electromagnetic shielding structure by itself, or a shielded wire that has an electromagnetic shielding structure by itself. Each wire 21 in this embodiment is a non-shielded wire.

[0023] As the core wire 22, for example, a stranded wire formed by twisting a plurality of metal strands or a single-core wire made of a single conductor can be used. As the single-core wire, for example, a columnar conductor composed of a single columnar metal rod having a solid structure inside or a tubular conductor having a hollow structure inside can be used. As the core wire 22, a combination of a stranded wire, a columnar conductor, and a tubular conductor may be used. As the material of the core wire 22, for example, a metal material such as a copper-based or aluminum-based material can be used.

[0024] The insulating coating 23 covers, for example, the outer peripheral surface of the core wire 22 over the entire circumferential direction. The insulating coating 23 is composed of, for example, a resin material having insulating properties. The cross-sectional shape of the wire 21 cut by a plane orthogonal to the length direction of each wire 21, that is, the cross-sectional shape of each wire 21, can be formed into an arbitrary shape. The cross-sectional shape of each wire 21 is formed into, for example, a circular shape, a semi-circular shape, a polygonal shape, a square shape, a flat shape, or the like. The cross-sectional shape of each wire 21 in this embodiment is formed into a circular shape.

[0025] The braided member 25, for example, has a cylindrical shape that collectively surrounds the outer circumferences of a plurality of electric wires 21 as a whole. As the braided member 25, for example, a braided wire formed by braiding a plurality of metal strands or a braided wire formed by combining a metal strand and a resin strand can be used. As the material of the metal strand, for example, a metal material such as a copper-based or aluminum-based material can be used. Although not shown, both ends in the length direction of the braided member 25 are grounded, for example, at connectors C1, C2 (see FIG. 1).

[0026] (Configuration of the exterior member 30) As shown in FIG. 3, the exterior member 30 has a cylindrical shape that surrounds the outer circumference of the wire member 20 over the entire circumferential direction. The exterior member 30 of the present embodiment is formed in a cylindrical shape. The exterior member 30, for example, has a continuous peripheral wall formed over the entire circumferential direction of the exterior member 30. The exterior member 30, for example, seals the inside of the exterior member 30 over the entire circumferential direction. The exterior member 30, for example, has a function of protecting the wire member 20 from flying objects and water droplets.

[0027] The exterior member 30, for example, has flexibility and can be easily bent. Examples of the exterior member 30 having flexibility include, for example, a resin corrugated tube or a rubber waterproof cover. The exterior member 30 of the present embodiment is a resin corrugated tube having a bellows shape in which the diameter repeats in a large and small pattern in the length direction of the exterior member 30. That is, the exterior member 30 of the present embodiment has a bellows structure in which large-diameter portions 31 and small-diameter portions 32 having a diameter smaller than that of the large-diameter portions 31 are alternately connected along the length direction of the exterior member 30. Each of the large-diameter portion 31 and the small-diameter portion 32, for example, forms an annular shape that makes one turn along the circumferential direction of the exterior member 30. As the material of the exterior member 30, for example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used.

[0028] (Configuration of the path restricting member 40) As shown in FIGS. 2 and 3, the wire harness 10 includes a path restricting member 40 attached to the outer periphery of the exterior member 30. The path restricting member 40 restricts the path along which the wire harness main body 11 is routed. Note that in FIG. 1, the illustration of the path restricting member 40 is omitted.

[0029] The path restricting member 40 holds the exterior member 30. The path restricting member 40 is, for example, harder than the exterior member 30. The path restricting member 40 has a hardness that makes it difficult to bend in a direction orthogonal to the length direction of the wire harness main body 11 as compared to the exterior member 30. Thereby, the path restricting member 40 restricts the path of the wire harness main body 11. For example, the path restricting member 40 assists the exterior member 30 so that the wire harness main body 11 does not deflect due to its own weight or the like and deviate from the desired path. The path restricting member 40 is provided partially in the length direction of the wire harness main body 11. The path restricting member 40 is attached to the outer periphery of the exterior member 30, for example, at a straight portion 11A that is a straight portion of the path of the wire harness main body 11.

[0030] As shown in FIG. 2, the path restricting member 40 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The path restricting member 40 has a shape that covers the outer periphery of the exterior member 30 at a part in the circumferential direction of the exterior member 30. The cross-sectional shape of the path restricting member 40 is generally C-shaped as a whole. The path restricting member 40 covers, for example, a range larger than half of the outer periphery of the exterior member 30. That is, the path restricting member 40 covers a range larger than half of the entire circumference in the circumferential direction of the outer periphery of the exterior member 30.

[0031] The path restricting member 40 extends along the length direction of the exterior member 30 at the straight portion 11A. The path restricting member 40 is formed in a shape that extends linearly in one direction, for example. The cross-sectional shape of the path restricting member 40 is uniform over the entire length in the length direction of the path restricting member 40, for example.

[0032] The path restricting member 40 is made of, for example, metal or resin. The path restricting member 40 of the present embodiment is made of resin. As the material of the path restricting member 40, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The path restricting member 40 can be manufactured by well-known manufacturing methods such as extrusion molding and injection molding. In the present embodiment, the path restricting member 40 is an extruded product manufactured by extrusion molding. Therefore, the path restricting member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the path restricting member 40 in the length direction. Also, a plurality of types of path restricting members 40 having different dimensions in the length direction can be manufactured using a single extrusion molding machine. For example, a plurality of types of path restricting members 40 having different dimensions in the length direction can be manufactured by cutting the base material of the path restricting member 40 formed by a single extrusion molding machine to an arbitrary length using a cutting machine.

[0033] The path restricting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the path restricting member 40. The insertion port 40X extends over the entire length direction of the path restricting member 40. The path restricting member 40 has a first end portion 41 and a second end portion 42 that are both end portions in the circumferential direction of the path restricting member 40 and form the insertion port 40X. The path restricting member 40 has a connecting portion 43 that connects the first end portion 41 and the second end portion 42. In other words, the path restricting member 40 has a connecting portion 43 formed to cover a part of the circumferential direction of the exterior member 30, a first end portion 41 and a second end portion 42 provided at both end portions of the connecting portion 43, and an insertion port 40X formed by the first end portion 41 and the second end portion 42.

[0034] The connecting portion 43 constitutes the main part of the path restricting member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the path restricting member 40. The cross-sectional shape of the connecting portion 43 is formed, for example, in a shape along the outer surface of the exterior member 30. The cross-sectional shapes of the first end portion 41, the second end portion 42, and the connecting portion 43 are formed, for example, in an arc shape.

[0035] The first end portion 41 and the second end portion 42 are provided on opposite sides in the circumferential direction of the path restricting member 40. The first end portion 41 and the second end portion 42 are provided apart from each other with the insertion port 40X therebetween in the circumferential direction of the path restricting member 40. In other words, a gap between the first end portion 41 and the second end portion 42 in the circumferential direction of the path restricting member 40 is configured as the insertion port 40X. Thus, the path restricting member 40 is formed in a C shape having the insertion port 40X in a part of the circumferential direction of the path restricting member 40.

[0036] The cross-sectional shapes of the tips of the first end portion 41 and the second end portion 42 are formed in a curved shape. The cross-sectional shapes of the tips of the first end portion 41 and the second end portion 42 in the present embodiment are formed in an arc shape.

[0037] The path restricting member 40 has a protruding portion 45 protruding from the inner surface of the first end portion 41 and a protruding portion 46 protruding from the inner surface of the second end portion 42. Each of the protruding portions 45, 46 protrudes toward the exterior member 30 inserted inside the path restricting member 40 and contacts the outer surface of the exterior member 30. Each of the protruding portions 45, 46 contacts the outer surface of the large-diameter portion 31 of the exterior member 30. The protruding portion 45 protrudes, for example, from the inner surface of the tip of the first end portion 41. The protruding portion 46 protrudes, for example, from the inner surface of the tip of the second end portion 42. The cross-sectional shapes of each of the protruding portions 45, 46 are formed in a curved shape, for example. The cross-sectional shapes of each of the protruding portions 45, 46 in the present embodiment are formed in an arc shape.

[0038] As shown in FIG. 3, each of the protruding portions 45, 46 extends in the length direction of the path restricting member 40. Each of the protruding portions 45, 46 extends, for example, over the entire length in the length direction of the path restricting member 40.

[0039] Each of the protruding portions 45, 46 presses the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is elastically sandwiched by the protruding portion 45, the protruding portion 46, and the connecting portion 43. Thereby, the connection of the path restricting member 40 to the exterior member 30 becomes strong.

[0040] As shown in FIG. 2, the opening width of the insertion port 40X, that is, the shortest distance between the first end portion 41 and the second end portion 42, is smaller than the outer diameter of the exterior member 30. The opening width of the insertion port 40X increases when the path restricting member 40 elastically deforms. For example, the opening width of the insertion port 40X increases when the exterior member 30 is inserted into the insertion port 40X from a direction orthogonal to the length direction of the path restricting member 40. When the exterior member 30 is inserted into the interior of the path restricting member 40, the path restricting member 40 elastically returns to try to return to its original shape. As a result, since the opening width of the insertion port 40X becomes smaller than the outer diameter of the exterior member 30, the path restricting member 40 is attached to the outer periphery of the exterior member 30.

[0041] (Configuration of the fixing member 50) As shown in FIG. 2, the wire harness 10 includes a fixing member 50 for fixing the wire harness main body 11 to a panel P that constitutes the floor portion of the vehicle V. One or more fixing members 50 are provided in the length direction of the wire harness main body 11. Note that in FIG. 1, the illustration of the fixing member 50 is omitted. The fixing member 50 holds, for example, a portion of the wire harness main body 11 where the path restricting member 40 is attached.

[0042] The fixing member 50 is made of, for example, metal or resin. The fixing member 50 of the present embodiment is made of resin. As the material of the fixing member 50, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The fixing member 50 can be manufactured by a well-known manufacturing method such as injection molding.

[0043] As shown in FIGS. 2 and 3, the fixing member 50 has a bolt fixing portion 51 fixed to a bolt B extending from the panel P, and a holding portion 52 that holds the wire harness main body 11.

[0044] (Configuration of the holding portion 52) The holding portion 52 holds the path restricting member 40 in a manner that covers the entire circumference of the path restricting member 40. The holding portion 52 has a holding portion main body 53 and a lid portion 54 connected to the holding portion main body 53.

[0045] The holding part main body 53 covers, for example, the outer periphery of the connecting part 43 in the path restricting member 40. The holding part main body 53 has an insertion port 55 covered by a lid part 54. The insertion port 55 opens in a direction orthogonal to the length direction of the wire harness main body 11. Note that the cross-sectional shape of the inner surface of the lid part 54 is formed, for example, in a shape along the outer surface of the exterior member 30.

[0046] The lid part 54 is integrally formed with the holding part main body 53, for example. The lid part 54 is connected to the holding part main body 53 by a hinge part 56, for example. The lid part 54 is rotatable about the hinge part 56 between an open position and a closed position covering the insertion port 55. Note that the lid part 54 shown in FIG. 2 is in the closed position, and the lid part 54 shown in FIG. 3 is in the open position.

[0047] Also, the lid part 54 has a locking claw 57. The locking claw 57 is locked to a lock part 58 provided on the holding part main body 53 in a state where the lid part 54 is in the closed position. Thereby, the lid part 54 is held in the closed position. Note that the wire harness main body 11 is held by the holding part 52 in a posture where the insertion port 40X faces the lid part 54 side.

[0048] As shown in FIGS. 2 and 3, the holding part 52 has a protrusion 59 protruding toward the inner peripheral side, that is, the wire harness main body 11 side. The protrusion 59 is formed so as to protrude from the inner surface of the lid part 54 in the holding part 52, for example. One or a plurality of protrusions 59 are provided.

[0049] In a state where the lid part 54 is in the closed position, the protrusion 59 is located inside the insertion port 40X of the path restricting member 40. Thereby, it becomes possible to restrict the relative rotation of the path restricting member 40 with respect to the holding part 52 by the protrusion 59. Also, the protrusion 59 fits into the small diameter part 32 of the exterior member 30. Thereby, the movement of the exterior member 30 with respect to the holding part 52 in the length direction of the exterior member 30 is suppressed.

[0050] (Configuration of the bolt fixing part 51) The bolt fixing portion 51 includes a fixing portion main body 61 and a locking ring 71 assembled to the fixing portion main body 61.

[0051] The fixing portion main body 61 is integrally formed with the holding portion main body 53, for example. The fixing portion main body 61 has an insertion hole 62 through which the bolt B is inserted. In FIGS. 2, 3, and 4, the width direction X, the depth direction Y, and the height direction Z are illustrated as three mutually orthogonal directions in the fixing member 50. The bolt B is inserted along the height direction Z into the insertion hole 62. Further, the wire harness main body 11 is disposed in the holding portion 52 such that its length direction is along the depth direction Y.

[0052] As shown in FIG. 2, the fixing portion main body 61 has a first side surface 61a facing the panel P in the mounted state to the vehicle V. The insertion hole 62 has an opening at one end side in the height direction Z on the first side surface 61a. That is, the insertion hole 62 has a bolt insertion port 63 into which the bolt B is inserted on the first side surface 61a. Note that the insertion hole 62 of the present embodiment is also open on both sides in the depth direction Y.

[0053] The fixing portion main body 61 has a second side surface 61b intersecting the first side surface 61a. The second side surface 61b is orthogonal to the first side surface 61a, for example. The second side surface 61b is a side surface on the side opposite to the side where the holding portion 52 is provided in the width direction X.

[0054] As shown in FIGS. 2 and 4, the insertion hole 62 has a first inner wall surface 62a and a second inner wall surface 62b facing each other in the width direction X. The fixing portion main body 61 has a ring insertion hole 64 communicating from the second side surface 61b to the first inner wall surface 62a. The ring insertion hole 64 opens on the second side surface 61b in a direction orthogonal to the height direction Z, for example, the width direction X. That is, the ring insertion hole 64 communicates the inside of the insertion hole 62 and the outside of the fixing portion main body 61 along the width direction X.

[0055] The fixing part body 61 has a recess 65 on the second inner wall surface 62b of the insertion hole 62. A part of the locking ring 71 is inserted into the recess 65. The recess 65 is provided at the same position as the ring insertion hole 64 in the height direction Z.

[0056] (Configuration of the locking ring 71) The locking ring 71 has, for example, a C shape when viewed from the height direction Z. That is, the locking ring 71 has a pair of end portions 72 and has a bolt assembly opening 73 between the pair of end portions 72. Further, the locking ring 71 has, for example, a flat plate shape in the height direction Z. The outer shape of the locking ring 71 is, for example, substantially circular. The locking ring 71 is made of, for example, resin or metal.

[0057] When assembling the fixing member 50 and the bolt B, first, the bolt B is inserted into the insertion hole 62 from the bolt insertion port 63 along the height direction Z. Thereafter, the locking ring 71 is assembled to the bolt B in the insertion hole 62. The locking ring 71 is inserted into the inside of the insertion hole 62 from the ring insertion hole 64 along the width direction X. At this time, the bolt B is inserted into the inner peripheral side of the locking ring 71 from the bolt assembly opening 73 along the radial direction of the locking ring 71. When the bolt B is inserted into the bolt assembly opening 73, the pair of end portions 72 are pushed apart by the bolt B. And when the bolt B is inserted into the inner peripheral side of the locking ring 71, the locking ring 71 elastically returns to its original shape. Note that the inner diameter of the locking ring 71 is set slightly smaller than the diameter D1 of the threaded portion Ba of the outer peripheral surface of the bolt B. That is, the locking ring 71 elastically sandwiches the bolt B.

[0058] Further, the locking ring 71 is axially locked to the threaded portion Ba of the outer peripheral surface of the bolt B. That is, the locking ring 71 is caught by the threaded portion Ba in the axial direction, and thereby the locking ring 71 is fixed to the bolt B so as not to move in the axial direction.

[0059] In the state where the locking ring 71 is fixed to the bolt B in this way, a part of the locking ring 71 is located inside the ring insertion hole 64. Thereby, the locking ring 71 can contact the inner surface of the ring insertion hole 64 in the height direction Z. Therefore, the relative movement of the locking ring 71 in the height direction Z is restricted by the inner surface of the ring insertion hole 64.

[0060] Also, in the state where the locking ring 71 is fixed to the bolt B, a part of the locking ring 71 is located inside the concave portion 65. Thereby, the locking ring 71 can contact the inner surface of the concave portion 65 in the height direction Z. Therefore, the relative movement of the locking ring 71 in the height direction Z is restricted by the inner surface of the concave portion 65. In the present embodiment, the relative movement of the locking ring 71 to both sides in the height direction Z is restricted by each of the ring insertion hole 64 and the concave portion 65.

[0061] The locking ring 71 is configured to be movable in a direction orthogonal to the axis of the bolt B inside the insertion hole 62. As shown in FIG. 4, each of the dimension L1 of the bolt insertion port 63 in the width direction X and the dimension L2 of the bolt insertion port 63 in the depth direction Y is larger than the diameter D1 of the threaded portion Ba. Thereby, in the state where the bolt B is inserted through the bolt insertion port 63, the movement of the bolt B and the locking ring 71 in the direction orthogonal to the axis is possible.

[0062] In the width direction X, the distance L3 from the inner side surface 65a of the concave portion 65 to the open end on the second side surface 61b of the ring insertion hole 64 is larger than the outer diameter D2 of the locking ring 71. Also, the dimension L4 of the ring insertion hole 64 in the depth direction Y is larger than the outer diameter D2 of the locking ring 71. The dimension L5 of the concave portion 65 in the depth direction Y is larger than the outer diameter D2 of the locking ring 71. Note that the dimension L4 of the ring insertion hole 64 and the dimension L5 of the concave portion 65 are set to be equal, for example. With such a dimension setting, a region where the locking ring 71 fixed to the bolt B can relatively move in a direction orthogonal to the axis of the bolt B is secured inside the insertion hole 62 including the ring insertion hole 64 and the concave portion 65.

[0063] The effects of the present embodiment will be described. (1) The bolt fixing portion 51 has a fixing portion main body 61 having an insertion hole 62 through which the bolt B is inserted. Further, the bolt fixing portion 51 has a locking ring 71 that is fixed to the bolt B by being axially locked to the threaded portion Ba of the bolt B disposed inside the insertion hole 62. The insertion hole 62 has a ring insertion hole 64 and a recess 65 that regulate the relative movement of the locking ring 71 in the axial direction of the bolt B. And the locking ring 71 is configured to be movable inside the insertion hole 62 in a direction orthogonal to the axis of the bolt B, that is, in the width direction X, the depth direction Y, and a direction obtained by combining them.

[0064] According to this configuration, the locking ring 71 fixed to the bolt B can maintain the state in which the bolt B is inserted into the insertion hole 62 because the relative movement of the locking ring 71 in the axial direction of the bolt B is regulated by the ring insertion hole 64 and the recess 65. And the locking ring 71 is configured to be movable inside the insertion hole 62 in a direction orthogonal to the axis of the bolt B. That is, relative movement in the direction orthogonal to the axis of the bolt B between the bolt B and the locking ring 71 and the fixing member 50 is allowed. For this reason, for example, even when the position of the fixing member 50 with respect to the bolt B is displaced in the direction orthogonal to the axis of the bolt B due to a deviation in the path of the wire harness 10 or the like, it is possible to stabilize the fixing of the fixing member 50 with respect to the bolt B.

[0065] (2) The locking ring 71 is configured to be movable inside the insertion hole 62 in both the width direction X orthogonal to the axial direction of the bolt B and the depth direction Y orthogonal to each of the axial direction and the width direction X of the bolt B. According to this configuration, it is possible to allow displacement between the bolt B and the fixing member 50 in the first direction and the second direction orthogonal to the axial direction of the bolt B. Therefore, it is possible to further stabilize the fixing of the fixing member 50 with respect to the bolt B.

[0066] (3) The fixing portion main body 61 has a ring insertion hole 64 that communicates with the insertion hole 62 and into which the locking ring 71 can be inserted. According to this configuration, it is possible to insert the locking ring 71 from the ring insertion hole 64 into the insertion hole 62 and fix it to the bolt B inside the insertion hole 62.

[0067] (4) The locking ring 71 has a C shape when viewed from the axial direction of the bolt B. According to this configuration, it becomes possible to facilitate the assembly of the locking ring 71 to the bolt B.

[0068] (5) The wire harness 10 includes an exterior member 30 that covers the outer periphery of the wire member 20, and a path restricting member 40 that is attached to the outer periphery of the exterior member 30 and restricts the path of the exterior member 30. The path restricting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the path restricting member 40 and extends over the entire length direction of the path restricting member 40. According to this configuration, in the wire harness 10 including the path restricting member 40, it becomes possible to stabilize the fixing of the fixing member 50 to the bolt B.

[0069] (6) The holding portion 52 holds the path restricting member 40 in a manner that covers the entire circumference of the path restricting member 40. The holding portion 52 has a protrusion 59 that protrudes toward the inner peripheral side. And the protrusion 59 is located inside the insertion port 40X. According to this configuration, it becomes possible to restrict the relative rotation of the path restricting member 40 with respect to the holding portion 52 by the protrusion 59 of the holding portion 52.
