Description

[Technical Field]

[0001] The present invention relates to a power supply device. [Background technology]

[0002] Conventionally, vehicles such as automobiles are equipped with a seat (a so-called sliding seat) that can slide along a rail member fixed to the vehicle body. The vehicle may also be equipped with an electrical component such as a seat heater. In this case, the vehicle is equipped with a power supply device for supplying power to the electrical component from a power source such as a secondary battery. The power supply device includes a bundle of electric wires, one end of which is electrically connected to the electrical component and the other end of which is electrically connected to the power source, for electrically connecting the electrical component and the power source, and a case fixed to the vehicle body and partially accommodating the bundle of electric wires. In this power supply device, one end of the bundle of electric wires moves back and forth along the rail member together with the seat in a sliding direction outside the case, and the bundle of electric wires moves in and out of the case in conjunction with the reciprocating movement of the one end of the bundle of electric wires. This type of power supply device is disclosed, for example, in Patent Document 1 listed below. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-136810 Summary of the Invention [Problem to be solved by the invention]

[0004] In this power supply device, the other end of the bundle of electric wires is also pulled out of the case, and the connector at the other end of the bundle of electric wires is connected to a mating connector on the power supply side outside the case. Therefore, after being pulled out of the case, the other end of the bundle of electric wires is routed to the position of the mating connector on the power supply side. Therefore, the longer the routing path of the other end of the bundle of electric wires, the more measures must be taken to prevent interference with surrounding components.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a power supply device according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] [Embodiment] An embodiment of a power supply device according to the present invention will be described with reference to FIGS.

[0011] 1 to 6, reference numeral 1 denotes a power supply device of this embodiment.

[0012] For example, a seat 500 installed in a vehicle such as an automobile may be equipped with electrical components 550 (FIG. 2). The electrical components 550 are devices provided in the seat 500, such as a seat heater, a seat ventilator, and a speaker, and require at least a supply of power.

[0013] Here, the seat 500 has a so-called slide seat that slides in a sliding direction along rail members 510 fixed to the vehicle body (not shown) (FIGS. 1 and 2). In such a vehicle, a pair of rail members 510 extending in the sliding direction are fixed to a floor panel of the vehicle body, and seat-side slide members 520 that can move back and forth in the sliding direction relative to the rail members 510 fixed to the vehicle body are supported. A seat-side slide member 520 is provided for each rail member 510. Each seat-side slide member 520 is supported so as to be able to move back and forth in the sliding direction relative to the pair of rail members 510, and is fixed to the seat 500 to hold the seat 500. For example, in this vehicle, a pair of rail members 510 extending in the vehicle's fore-and-aft direction are arranged at an interval from each other in the vehicle width direction, and the seat 500 held by each seat-side slide member 520 moves back and forth in the vehicle's fore-and-aft direction along the rail members 510. The figure shows one of a pair of rail members 510 and a seat-side slide member 520 supported by this rail member 510. The sliding movement of the seat 500 may be manual or electric.

[0014] The power supply device 1 shown here is a device for supplying power from a power source (not shown) such as a secondary battery to electrical components 550 of a seat 500 that is reciprocally movable in a sliding direction.

[0015] The power supply device 1 includes a bundle of electric wires 10 that supplies power to at least an electrical component 550, a case 20 that partially accommodates the bundle of electric wires 10, and a power supply side slide member 30 that is assembled to a seat side slide member 520 and is integral with the seat side slide member 520 and can move back and forth in the sliding direction relative to a rail member 510 (FIGS. 1 to 4).

[0016] The electric wire bundle 10 is a bundle of multiple electric wires. The electric wire bundle 10 shown here is bundled together by wrapping, for example, a resin tape around the multiple electric wires. The electric wire bundle 10 is covered with an exterior part 15 such as a corrugated tube at locations that require enhanced protection, such as locations that are subject to sliding resistance (FIGS. 1 to 4).

[0017] This wire bundle 10 has an accommodation target portion 11 to be accommodated in a case 20, and one end side 12 and the other end side 13 to be drawn out from the case 20 (FIGS. 1, 3, and 4). In this wire bundle 10, a connector (not shown) at the end of the one end side 12 is connected to a mating connector (not shown) on the electrical component 550 side, and a connector (not shown) at the end of the other end side 13 is connected to a mating connector (not shown) on the power source side.

[0018] The case 20 shown here is molded from a synthetic resin material. This case 20 is fixed to the vehicle body so as not to displace relative to the vehicle body. For example, this case 20 is fixed to the vehicle body or a rail member 510. Here, the case 20 is fixed to one of a pair of rail members 510. The case 20 shown here also includes a first case member 20A and a second case member 20B that are assembled together (FIGS. 1 to 5).

[0019] The case 20 has an electric wire accommodating chamber 21 that accommodates the accommodation target portion 11 of the electric wire bundle 10 therein (FIGS. 1, 3, 5, and 6). The case 20 has an opening (hereinafter referred to as a "first outlet") 22a through which one end side 12 of the electric wire bundle 10 is drawn out of the electric wire accommodating chamber 21, and an opening (hereinafter referred to as a "second outlet") 22b through which the other end side 13 of the electric wire bundle 10 is drawn out of the electric wire accommodating chamber 21 (FIG. 3). In the electric wire bundle 10, the accommodation target portion 11 inside the electric wire accommodating chamber 21 is covered with an exterior part 15. In the electric wire bundle 10, the one end side 12 together with the exterior part 15 is drawn out of the electric wire accommodating chamber 21 from the first outlet 22a, and the other end side 13 together with the exterior part 15 is drawn out of the electric wire accommodating chamber 21 from the second outlet 22b.

[0020] A power supply side slide member 30 is attached to one end 12 of the electric wire bundle 10 at the end where it is pulled out from the first outlet 22a (FIG. 3). One end of the exterior component 15 pulled out from the first outlet 22a is fixed to this power supply side slide member 30. Then, this power supply side slide member 30 pulls out one end 12 of the electric wire bundle 10 pulled out from one end of the exterior component 15 toward a mating connector on the electrical component 550 side (not shown). The power supply side slide member 30 shown here is molded from a synthetic resin material.

[0021] Here, the power supply-side slide member 30 is held by the sheet-side slide member 520 by a holding mechanism such as a locking mechanism using a claw or the like, which will not be described in detail, and is reciprocated in the sliding direction in conjunction with the reciprocating movement of the sheet-side slide member 520 along the rail member 510. In other words, the power supply-side slide member 30 is assembled to the one end side 12 of the electric wire bundle 10 and the sheet-side slide member 520, respectively, and can reciprocate in the sliding direction relative to the rail member 510 integrally with the one end side 12 of the electric wire bundle 10, the sheet-side slide member 520, and the sheet 500. Therefore, in the case 20, the accommodation target portion 11 in the wire accommodating chamber 21 is moved in and out through the first outlet 22a in conjunction with the reciprocating movement of the one end side 12 of the electric wire bundle 10. Therefore, the excess length of the electric wire bundle 10 that is moved in and out in conjunction with the reciprocating movement of the one end side 12 of the electric wire bundle 10 is accommodated in the wire accommodating chamber 21 as the accommodation target portion 11.

[0022] The wire accommodating chamber 21 shown here is formed as an oval space with its longitudinal direction being the sliding direction of the sheet 500, etc., in order to facilitate the insertion and removal of the accommodation target portion 11 of the wire bundle 10. When the accommodation target portion 11 of the wire bundle 10 is fully accommodated in the wire accommodating chamber 21, it is routed around the entire circumference along the oval vertical wall of the wire accommodating chamber 21. The first outlet 22a shown here opens toward one side in the sliding direction in order to facilitate the insertion and removal of the accommodation target portion 11 of the wire bundle 10. The first outlet 22a is disposed at one end of the arc shape of one semicircular portion of the wire accommodating chamber 21, and opens toward one end of the arc shape of the other semicircular portion.

[0023] Here, the rail member 510 is disposed on one side of the electric wire accommodating chamber 21 in a direction perpendicular to the sliding direction and the vehicle up-down direction. One end side 12 of the electric wire bundle 10 together with the exterior part 15 is pulled out from the first pull-out opening 22a, and then inserted into the rail member 510 from the end, and assembled to the power supply-side slide member 30 within the rail member 510. Therefore, the power supply-side slide member 30 is disposed on one side of the electric wire accommodating chamber 21 in a direction perpendicular to the sliding direction and the vehicle up-down direction. The accommodation target portion 11 of the electric wire bundle 10 is inserted and removed from the first pull-out opening 22a along the sliding direction. Hereinafter, when the term "perpendicular direction" is simply used without any particular mention, the "perpendicular direction" refers to the direction perpendicular to the sliding direction and the vehicle up-down direction.

[0024] In this case 20, similar to the first outlet 22a, the second outlet 22b is also arranged at one end of the arc shape of one semicircular portion of the electric wire accommodating chamber 21 (FIG. 3). Therefore, the second outlet 22b opens in the opposite direction to the first outlet 22a and faces the other side in the sliding direction.

[0025] The wire accommodating chamber 21, the first outlet 22a, and the second outlet 22b are formed by assembling the first case member 20A and the second case member 20B together. For example, an oval space forming the wire accommodating chamber 21, a U-shaped notch forming the first outlet 22a, and a U-shaped notch forming the second outlet 22b are formed in one of the first case member 20A and the second case member 20B. The other of the first case member 20A and the second case member 20B is formed with a cover main wall 23a that covers the opening of the oval space forming the wire accommodating chamber 21, the U-shaped opening in the notch forming the first outlet 22a, and the U-shaped opening in the notch forming the second outlet 22b (FIGS. 3 and 4). Thus, the wire accommodating chamber 21 is formed inward by assembling the first case member 20A and the second case member 20B together and covering the opening of an oval space in one of them with the cover main wall body 23a in the other case member. The opening of the oval space is the insertion opening 21a for inserting the wire bundle 10 into the wire accommodating chamber 21 (FIG. 3). The first outlet 22a and the second outlet 22b are formed by assembling the first case member 20A and the second case member 20B together and covering two U-shaped openings in one of them with the cover main wall body 23a in the other case member. Here, the oval space forming the wire accommodating chamber 21, the U-shaped notches forming the first outlet 22a, and the U-shaped notches forming the second outlet 22b are formed in the first case member 20A. Here, the cover main wall body 23a is formed in the second case member 20B.

[0026] Meanwhile, the other end 13 of the electric wire bundle 10 is pulled out from the second outlet 22b to the outside of the electric wire accommodating chamber 21, and then routed around the periphery of the electric wire accommodating chamber 21 and then routed to the position of the mating connector on the power source side. Therefore, in this power supply device 1, the path of the other end 13 of the electric wire bundle 10 is restricted at least around the electric wire accommodating chamber 21 to prevent interference of the other end 13 with peripheral components around the electric wire accommodating chamber 21. For this purpose, the case 20 has a path restriction part 24 that holds the path restriction target part 13a at the other end 13 of the electric wire bundle 10 pulled out from the second outlet 22b outside the electric wire accommodating chamber 21 (FIGS. 1 to 8).

[0027] The other end 13 of the electric wire bundle 10 shown here is routed along one semicircular portion of the electric wire accommodating chamber 21 from one end of the arc to the other end, and is routed on the other side of the electric wire accommodating chamber 21 in the orthogonal direction toward the other end of the arc of the other semicircular portion of the electric wire accommodating chamber 21 along the longitudinal direction (sliding direction) of the electric wire accommodating chamber 21 ( FIGS. 1 , 3 , and 4 ). Therefore, on the other end 13 of the electric wire bundle 10, the portion routed along the longitudinal direction of the electric wire accommodating chamber 21 on the other side is referred to as a path regulation target portion 13a. The case 20 regulates the path of the path regulation target portion 13a routed on the other side of the electric wire accommodating chamber 21. Therefore, the path regulation portion 24 shown here is disposed on the other side of the electric wire accommodating chamber 21 in the orthogonal direction.

[0028] This path regulation section 24 includes a path regulation passage 25 that accommodates and routes the path regulation target section 13a within the passage, and at least one wire locking section 26 that locks the path regulation target section 13a within the path regulation passage 25 and keeps it within the passage (Figures 1, 3, 5, and 6).

[0029] The path-regulating passage 25 shown here is formed in a gutter shape extending in the sliding direction. Therefore, this path-regulating passage 25 is an opening along the wiring path of the path-regulating target portion 13a, and has an insertion opening 25a for inserting the path-regulating target portion 13a into the passage (FIGS. 3 and 5). In this case 20, the insertion opening 25a is closed by assembling the first case member 20A and the second case member 20B to each other. Therefore, the path-regulating target portion 13a shown here is not covered with the exterior part 15.

[0030] The path-regulating passage 25 shown here is adjacent to the other side of the wire accommodating chamber 21 in the orthogonal direction ( FIGS. 1 , 3 , and 7 ). The path-regulating passage 25 shown here extends along the arc to the other end of the arc of one semicircular portion of the wire accommodating chamber 21, and also extends along the arc to the other end of the arc of the other semicircular portion of the wire accommodating chamber 21. The path-regulating passage 25 is formed between a first wall body 25 b and a second wall body 25 c that are spaced apart from each other and extend between the other ends of the first wall body 25 b and the second wall body 25 c ( FIGS. 3 , 5 to 7 ). One ends of the first wall body 25 b and the second wall body 25 c along the wiring path of the path-regulating target portion 13 a are connected by a trough-shaped bottom wall 25 d, and the first wall body 25 b and the second wall body 25 c hang down in the same direction from the bottom wall 25 d ( FIGS. 5 and 6 ). In the first wall 25b and the second wall 25c shown here, the amount of protrusion of the second wall 25c from the bottom wall 25d in the vertical direction is smaller than the amount of protrusion of the first wall 25b from the bottom wall 25d in the vertical direction. Therefore, an insertion opening 25a is formed between the other end of the second wall 25c along the wiring path of the path-regulated portion 13a and the wall surface of the first wall 25b, facing the bottom wall 25d with a gap therebetween. Therefore, in the first wall 25b, the other end of the path-regulated portion 13a along the wiring path protrudes beyond the insertion opening 25a.

[0031] Only one type or multiple types of electric wire locking portions 26 may be provided. The path regulation portion 24 shown here includes, as electric wire locking portions 26, at least one first electric wire locking portion 26A (FIGS. 1, 3, and 5 to 7) provided in the path regulation passage 25, and at least one second electric wire locking portion 26B (FIGS. 4 to 6 and 8) that is inserted into the path regulation passage 25 from the insertion opening 25a and suppresses movement of the path regulation target portion 13a in the passage toward the insertion opening 25a.

[0032] The path-regulating passage 25 and the first electric wire locking portion 26A are provided in either the first case member 20A or the second case member 20B. The second electric wire locking portion 26B is provided in the other of the first case member 20A or the second case member 20B. Here, the path-regulating passage 25 and the first electric wire locking portion 26A are provided in the first case member 20A, and the second electric wire locking portion 26B is provided in the second case member 20B (FIGS. 1, 3, and 4).

[0033] A plurality of first wire locking portions 26A are provided at intervals from one another in a direction along the wiring path of the path-regulated portion 13a (FIGS. 1, 3, and 7). Each of the first wire locking portions 26A is a cantilevered protrusion that protrudes from the first wall body 25b and is spaced apart from the bottom wall 25d by at least the maximum dimension of the wire bundle 10 (or the diameter of the bundle if the wires are bundled in a circle) (FIGS. 3, 5, and 6).

[0034] The first wire locking portion 26A prevents the path-restricted portion 13a of the electric wire bundle 10 inserted between the first wire locking portion 26A and the bottom wall 25d from moving toward the insertion opening 25a (FIGS. 5 and 6). For this reason, the first wire locking portion 26A protrudes from the first wall 25b by an amount of protrusion that is at least the maximum dimension of the electric wire bundle 10. Furthermore, the first wire locking portion 26A is formed so that a gap of at least the maximum dimension of the electric wire bundle 10 is left between its free end and the second wall 25c. As a result, the path-restricted portion 13a of the electric wire bundle 10 is inserted through the insertion opening 25a, passes between the free end of the first wire locking portion 26A and the second wall 25c, and is then inserted between the first wire locking portion 26A and the bottom wall 25d.

[0035] The first wire locking portion 26A shown here has an end portion on the insertion opening 25a side formed as an inclined portion 26a that moves away from the insertion opening 25a the further it protrudes (FIG. 5). In this first wire locking portion 26A, the inclined portion 26a makes it easier to guide the path-regulated portion 13a of the wire bundle 10 inserted through the insertion opening 25a between the free end and the second wall body 25c.

[0036] Incidentally, a notch 25c1 is formed in the second wall 25c at a portion facing the first electric wire locking portion 26A in the protruding direction of the first electric wire locking portion 26A (FIGS. 3 to 5 and 7). This notch 25c1 is intended to improve the ease of insertion of the path-regulated portion 13a of the electric wire bundle 10 from the insertion opening 25a to between the first electric wire locking portion 26A and the bottom wall 25d, and is cut into, for example, a rectangular or trapezoidal shape larger than the finger of an operator.

[0037] Here, the first case member 20A is provided with a wall 27a that forms part of the standing wall of the electric wire accommodating chamber 21 on the other side of the electric wire accommodating chamber 21 in the orthogonal direction (FIGS. 3 and 5 to 7). In this first case member 20A, the wall 27a forms a partition that separates the electric wire accommodating chamber 21 from the path regulating passage 25. Therefore, here, the wall 27a is used as the first wall 25b that forms the path regulating passage 25. Moreover, this first case member 20A is formed so that the insertion opening 21a of the electric wire accommodating chamber 21 and the insertion opening 25a of the path regulating passage 25 open in the same direction (FIGS. 3 and 5).

[0038] By assembling the first case member 20A and the second case member 20B together, the insertion opening 21a of the wire accommodating chamber 21 is covered by the cover main wall 23a of the second case member 20B. On the other hand, by assembling the first case member 20A and the second case member 20B together, the insertion opening 25a of the path regulating passage 25 is covered by the blocking wall 23b of the second case member 20B (FIGS. 3 and 5).

[0039] The second case member 20B shown here has a cover side wall 23c that stands upright from the cover main wall 23a and externally covers the other end of the wall 27a (first wall 25b) of the first case member 20A that is along the wiring path of the path-restricted portion 13a (FIGS. 3, 5, 6, and 8). The blocking wall 23b stands upright from the end of the cover side wall 23c on the protruding direction side. The second case member 20B has a side wall 23d that stands upright from the end of the blocking wall 23b on the protruding direction side and externally covers the other end of the second wall 25c of the first case member 20A that is along the wiring path of the path-restricted portion 13a (FIGS. 3, 5, 6, and 8).

[0040] The second wire locking portions 26B are protrusions that protrude from the blocking wall 23b and the side wall 23d (FIGS. 5 and 6). A plurality of the second wire locking portions 26B are provided at intervals from each other in a direction along the wiring path of the path-regulated portion 13a. Here, a plurality of pairs of second wire locking portions 26B spaced apart in a direction along the wiring path are provided at even greater intervals in a direction along the wiring path. In the second wall 25c, a notch 25c2 is formed for each combination of a pair of second wire locking portions 26B to avoid the pair of second wire locking portions 26B so that the pair of second wire locking portions 26B can be inserted into the path-regulated passage 25 (FIGS. 3, 4, 6, and 7).

[0041] The second wire locking portion 26B shown here has an end portion on the protruding side from the blocking wall 23b that is positioned closer to the bottom wall 25d than the first wire locking portion 26A within the path-regulating passage 25 ( FIGS. 5 and 6 ). The second wire locking portion 26B shown here has an inclined portion 26b formed at an end portion that faces the first wall 25b (wall 27a) within the path-regulating passage 25, the inclined portion 26b gradually increasing in distance from the first wall 25b (wall 27a) as it approaches the bottom wall 25d ( FIGS. 5 and 6 ). The inclined portion 26b is located at least closer to the bottom wall 25d than the first wire locking portion 26A. The inclined portion 26b of the second wire locking portion 26B prevents the path-regulating target portion 13a of the wire bundle 10 from coming into contact with the corner.

[0042] In this path regulation section 24, a first wire locking section 26A and a pair of second wire locking sections 26B are arranged with their positions shifted from each other in a direction along the wiring path of the path regulation target section 13a (Figures 3, 4, 7 and 8).

[0043] The first case member 20A and the second case member 20B are held in their assembled state by a holding mechanism 28 at multiple locations that utilize claws or the like provided between them ( FIGS. 2 to 4 , 7 , and 8 ). The holding mechanism 28 includes a first locking portion 28a provided on the second wall 25c of the first case member 20A and a second locking portion 28b provided on the side wall 23d of the second case member 20B that locks the first case member 20A and the second case member 20B to the first locking portion 28a while the first case member 20A and the second case member 20B remain in their assembled state ( FIGS. 3 , 4 , 7 , and 8 ). The holding mechanism 28 is disposed, for example, between two pairs of second wire locking portions 26B in the wiring path of the route-regulated target portion 13a.

[0044] As described above, in the power supply device 1 of this embodiment, the other end 13 of the electric wire bundle 10 is pulled out from the electric wire accommodating chamber 21 of the case 20, but the routing path of the path regulation target portion 13a at the other end 13 can be regulated by the path regulation portion 24 of the case 20. Therefore, the power supply device 1 can prevent the other end 13 of the electric wire bundle 10 from interfering with surrounding components.

[0045] Furthermore, in the power supply device 1 of this embodiment, the path regulation portion 24 includes a path regulation passage 25 and a first electric wire locking portion 26A provided in the first case member 20A, and a second electric wire locking portion 26B provided in the second case member 20B. In this power supply device 1, the path regulation target portion 13a of the electric wire bundle 10 is inserted into the path regulation passage 25, and the path regulation target portion 13a is inserted between the first electric wire locking portion 26A and the bottom wall 25d of the path regulation passage 25. Then, the first case member 20A and the second case member 20B are assembled, and the second electric wire locking portion 26B is inserted into the path regulation passage 25. Therefore, in this power supply device 1, even if the path regulation target portion 13a rises toward the insertion opening 25a between two adjacent first wire locking portions 26A, the second wire locking portion 26B can press the raised portion of the path regulation target portion 13a toward the bottom wall 25d in conjunction with the assembling operation of the first case member 20A and the second case member 20B. Therefore, this power supply device 1 can prevent the path regulation target portion 13a from getting caught between the first case member 20A and the second case member 20B when assembling the first case member 20A and the second case member 20B.

[0046] Furthermore, in the power supply device 1 of this embodiment, the routing path of the path-restricted portion 13a can be restricted simply by inserting the path-restricted portion 13a of the electric wire bundle 10 into the path-restricting passage 25 and then assembling the first case member 20A and the second case member 20B. In other words, the path-restricting portion 24 of this power supply device 1 can restrict the routing path of the path-restricted portion 13a without using other components such as cable ties or tape. Therefore, this power supply device 1 can improve the ease of assembly when assembling the electric wire bundle 10 and the case 20.

[0047] In this power supply device 1, for example, the wire bundle 10 is assembled to the first case member 20A placed on a workbench or the like with the insertion openings 21a, 25a facing vertically upward, and the second case member 20B is assembled to the first case member 20A. When this power supply device 1 is mounted on a vehicle, the second case member 20B is assembled to the vehicle body side with the second case member 20B positioned vertically below the first case member 20A.

[0048] In the power supply device 1, the path regulator 24 may be replaced with any of the following path regulators 124, 224, and 324 (see FIGS. 9 to 11). When using the path regulators 124, 224, and 324, the first case member 20A and the second case member 20B are configured without the path regulator passage 25 and other components associated with the path regulator 24. Therefore, in the first case member 20A shown here, the wall 27a is the outermost wall on the other side of the electric wire accommodating chamber 21 in the orthogonal direction. The second case member 20B shown here has a cover-side wall 23c that covers the wall 27a from the outside. When using the path regulators 124, 224, and 324, the path-regulated portion 13a of the electric wire bundle 10 is covered with an exterior component 15.

[0049] The path regulation portion 124 includes a wire accommodating portion 124a that protrudes from the outer wall surface of the wall 27a of the first case member 20A and accommodates a part of the path regulation target portion 13a of the wire bundle 10 by inserting it into a groove through an opening, and a blocking portion 124b that protrudes from the outer wall surface of the cover side wall 23c of the second case member 20B and blocks the opening of the wire accommodating portion 124a when the first case member 20A and the second case member 20B are in an assembled state (FIG. 9).

[0050] A holding mechanism using a claw or the like is provided between the electric wire accommodating portion 124a and the blocking portion 124b. The holding mechanism includes a first locking portion 124c provided in the electric wire accommodating portion 124a and a second locking portion 124d provided in the blocking portion 124b, and when the first case member 20A and the second case member 20B are in an assembled state, the first locking portion 124c and the second locking portion 124d are arranged in a state where they can be locked together so that the electric wire accommodating portion 124a and the blocking portion 124b do not separate (FIG. 9).

[0051] A plurality of the path regulation parts 124 are provided at intervals from each other in a direction along the wiring path of the path regulation target part 13a.

[0052] The path regulator 224 is provided in either the first case member 20A or the second case member 20B. Here, the path regulator 224 is provided in the second case member 20B. The path regulator 224 protrudes from the outer wall surface of the cover side wall 23c of the second case member 20B and includes a wire accommodating portion 224a that protrudes from the outer wall surface of the cover side wall 23c of the second case member 20B and accommodates a part of the path regulation target portion 13a of the electric wire bundle 10 by inserting it into a groove from an opening, and a closing portion 224b that closes the opening of the wire accommodating portion 224a (FIG. 10). The path regulator 224 also includes a hinge portion 224c, such as a living hinge, that connects the wire accommodating portion 224a and the closing portion 224b and rotates the closing portion 224b relative to the wire accommodating portion 224a between the open position and the closed position (FIG. 10). The open position refers to a position of the blocking portion 224b where the path regulation target portion 13a can be inserted into the groove of the electric wire accommodating portion 224a. The closed position refers to a position of the blocking portion 224b where the opening of the electric wire accommodating portion 224a is blocked. Although not shown, this path regulation portion 224 is provided with a holding mechanism that uses a claw portion or the like to hold the blocking portion 224b in the electric wire accommodating portion 224a in the closed position.

[0053] A plurality of the path regulation parts 224 are provided at intervals from each other in a direction along the wiring path of the path regulation target part 13a.

[0054] The path regulator 324 includes a pair of first wire accommodating sections 324a that protrude from the outer wall surface of the wall 27a of the first case member 20A at intervals in a direction along the routing path of the path-regulation target sections 13a. The first wire accommodating sections 324a accommodate a portion of the path-regulation target sections 13a of the wire bundle 10 by inserting the portion into a groove through an opening. The second wire accommodating section 324b protrudes from the outer wall surface of the cover-side wall 23c of the second case member 20B between the pair of first wire accommodating sections 324a. The second wire accommodating section 324b accommodates a portion of the path-regulation target sections 13a of the wire bundle 10 by inserting the portion into the groove through an opening (FIG. 11). The pair of first wire accommodating sections 324a and the pair of second wire accommodating sections 324b are formed so that their grooves are coaxially arranged. In the path regulator 324, the openings of the pair of first wire accommodating sections 324a and the opening of the second wire accommodating section 324b are open in opposite directions. This path regulation portion 324 positions the path regulation target portion 13a in the grooves of the pair of first electric wire accommodating portion 324a and second electric wire accommodating portion 324b by assembling the first case member 20A and the second case member 20B together.

[0055] A plurality of the path regulation parts 324 are provided at intervals from each other in a direction along the wiring path of the path regulation target part 13a. [Explanation of symbols]
