The second groove 27 reaches the third end face 25 and the fourth end face 26.

The connection portion 19 is located between the second end face 23 and the third end face 25 at a position that does not overlap with the first axis X and the second axis Y. The connection portion 19 is formed in a plate shape and connects one side wall 24B of the first portion 17 and the other side wall 27B of the second portion 18. The connection portion 19, the second end face 23, and the third end face 25 form a third groove 28. The third groove 28 extends in a direction perpendicular to each of the first axis X and the second axis Y. The third groove 28 is connected to the end of the first groove 24 on the second end face 23 side and is connected to the end of the second groove 27 on the third end face 25 side. The opening direction of the first groove 24 coincides with one of the extension directions of the third groove 28, and the opening direction of the second groove 27 coincides with the other of the extension directions of the third groove 28. That is, the first groove 24 and the second groove 27 open in opposite directions.

The first groove 24 receives at least a part of the first rod-shaped portion 15. A pair of first protrusions 29 protruding in a direction approaching each other are provided on the open end sides of the inner surfaces of the pair of side walls 24B that form the first groove 24. The pair of first protrusions 29 set the width of the first groove 24 at the open end to be smaller than the diameter of the first rod-shaped portion 15. A pair of edges 24C that form the open end of the first groove 24 are inclined so as to approach each other toward the bottom 24A side of the first groove 24. Specifically, the surfaces on the open end sides of the pair of first protrusions 29 are inclined so as to approach each other toward the bottom 24A side of the first groove 24.

The second groove 27 receives at least a part of the second rod-shaped portion 16. A pair of second protrusions 30 protruding toward each other are provided on the inner surface of the opening end side of the pair of side walls 27B that form the second groove 27. The pair of second protrusions 30 set the width of the opening end of the second groove 27 to be smaller than the diameter of the second rod-shaped portion 16. A pair of edges 27C that form the opening end of the second groove 27 are inclined so as to approach each other toward the bottom 27A side of the second groove 27. Specifically, the surfaces on the opening end side of the pair of second protrusions 30 are inclined so as to approach each other toward the bottom 27A side of the second groove 27.

The outer surface of the side wall 24B of the first portion 17 is provided with an engagement portion 31 for engaging the wire 12 with the upper member 10. As shown in FIG. 6, the upper member 10 has a plurality of engagement holes 32 for engaging the clip 13. In this embodiment, the engagement holes 32 are formed in the left and right portions of the front wall portion 10A of the upper member 10, one each. Each engagement hole 32 is formed in the front-rear direction with respect to the upper member 10. The engagement portion 31 is flexible and is formed, for example, of resin. The engagement portion 31 has a support portion 33 extending substantially perpendicularly from the outer surface of the side wall 24B of the first portion 17, and a plurality of elastic claws 34 extending from the tip 33B of the support portion 33 toward the base end 33A of the support portion 33. In this embodiment, the elastic claws 34 are a pair of elastic claws 34 formed symmetrically with respect to the support portion 33 and aligned along the first axis X. Each elastic claw 34 has a base 34A on the tip 33B of the support portion 33. Each elastic claw 34 has a free end 34B that extends away from the outer circumferential surface of the support portion 33 as it moves from the base 34A toward the base end 33A.

The method of fixing the wire 12 to the upper member 10 is as follows. First, the worker places the clip 13 behind the bent portion 14 of the wire 12 so that the third groove 28 opens forward and extends left and right. Then, the worker receives the bent portion 14 of the wire 12 from the front into the third groove 28. Next, the worker rotates the clip 13 around an axis that passes through the third groove 28 and extends forward and backward. As a result, the first rod-shaped portion 15 enters the first groove 24, and the second rod-shaped portion 16 enters the second groove 27. At this time, the first rod-shaped portion 15 passes between the pair of first protrusions 29, and the second rod-shaped portion 16 passes between the pair of second protrusions 30. As a result, the first rod-shaped portion 15 is engaged between the pair of first protrusions 29, and the second rod-shaped portion 16 is engaged with the pair of second protrusions 30, so that the clip 13 is connected to the wire 12.

Next, the worker inserts the engagement portion 31 of the clip 13 connected to the wire 12 into the engagement hole 32. This fixes the clip 13 to the upper member 10.

The wire 12 has a first rod-shaped portion 15 and a second rod-shaped portion 16 via a bent portion 14, the first groove 24 of the clip 13 clamps the first rod-shaped portion 15, and the second groove 27 of the clip 13 receives the second rod-shaped portion 16, so that it is easy to determine the position of the clip 13 relative to the wire 12 and to perform assembly work. The first groove 24 and the second groove 27 open in different directions, and the opening width of the first groove 24 is smaller than the diameter of the first rod-shaped portion 15 due to the first protrusion 29, and the opening width of the second groove 27 is smaller than the diameter of the second rod-shaped portion 16 due to the second protrusion 30, so that the clip 13 is unlikely to fall off the wire 12. In addition, a pair of edges 24C that form the opening end of the first groove 24 are inclined so as to approach each other toward the bottom 24A side of the first groove 24, and a pair of edges 27C that form the opening end of the second groove 27 are inclined so as to approach each other toward the bottom 27A side of the second groove 27. Due to the structure of each edge 24C, 27C, when an operator pushes the wire 12 into the first groove 24 and the second groove 27, the first groove 24 and the second groove 27 can easily receive the wire 12.

The third groove 28 is formed by the connection portion 19, the second end face 23, and the third end face 25, and the first groove 24 and the second groove 27 are each open toward at least a part of the extension direction of the third groove 28. With this structure, the operator can easily engage the first groove 24 with the first rod-shaped portion 15 and the second groove 27 with the second rod-shaped portion 16 by receiving the bent portion 14 of the wire 12 in the third groove 28 from the front and then rotating the clip 13 around an axis that passes through the third groove 28 and extends forward and backward. Since the angle between the first axis X and the second axis Y is set to be equal to the inclination angle α between the first rod-shaped portion 15 and the second rod-shaped portion 16, the positioning of the clip 13 with respect to the wire 12 can be performed with a simple structure. The front wall 10A of the upper member 10 has an engagement hole 32, so the engagement portion 31 provided on the first part 17 of the clip 13 can be inserted into the engagement hole 32 from the front.

The clip 213 and vehicle seat 1 according to the second embodiment are different from the clip 13 and vehicle seat 1 according to the first embodiment in the shape of the clip 213 and the shape of the wire 212.

Specifically, the surfaces on the opening end side of the pair of third protrusions 238 are inclined so as to approach each other toward the bottom 228A side of the third groove 228.

The wire 212 is fixed to the upper member 10 in the following manner. The worker pushes the first rod-shaped portion 215 into the first groove 224, the second rod-shaped portion 216 into the second groove 227, and the intermediate rod-shaped portion 214 into the third groove 228 from the front to receive them. At this time, the first rod-shaped portion 215 passes between the pair of first protrusions 29, the second rod-shaped portion 216 passes between the pair of second protrusions 30, and the intermediate rod-shaped portion 214 passes through the third protrusion 238. As a result, the first rod-shaped portion 215 is engaged between the pair of first protrusions 29, the second rod-shaped portion 216 is engaged with the pair of second protrusions 30, and the intermediate rod-shaped portion 214 is engaged with the third protrusion 238, so that the clip 213 is connected to the wire 212.

Next, the worker inserts the engagement portion 31 of the clip 213 connected to the wire 212 into the engagement hole 32. This fixes the clip 213 to the upper member 10.

The first groove 224 receives the first rod portion 215, the second groove 227 receives the second rod portion 216, and the third groove 228 receives the intermediate rod portion 214. This configuration allows the clip 213 to be more stably connected to the wire 212.

The clip 313 and vehicle seat 1 according to the third embodiment are different from the clip 213 and vehicle seat 1 according to the second embodiment in the shape of the clip 313 and the shape of the wire 312. In the following explanation, only the different configurations will be explained, and the explanation of the same configurations as the clips 13, 213 and vehicle seat 1 according to the first and second embodiments will be omitted by referring to the above description.

As shown in FIG. 8, the wire 312 has a fourth rod-shaped portion 339 extending rearward from the upper end of the first rod-shaped portion 215. A fourth groove 340 extending along the support portion 33 is formed in the support portion 33 of the engagement portion 31. The fourth groove 340 opens in the same direction as the first groove 224. One end of the fourth groove 340 is connected to the first groove 224. The other end of the fourth groove 340 may or may not reach the tip 33B of the support portion 33.

The fourth groove 340 receives the fourth rod-shaped portion 339. A pair of fourth protrusions 341 protruding toward each other are provided on the inner surface of the opening end side of the pair of side walls 340B that form the fourth groove 340. The pair of fourth protrusions 341 set the width of the opening end of the fourth groove 340 to be smaller than the middle diameter. A pair of edges 340C that form the opening end of the fourth groove 340 are inclined so as to approach each other toward the bottom 340A side of the fourth groove 340. Specifically, the surfaces on the opening end side of the pair of fourth protrusions 341 are inclined so as to approach each other toward the bottom 340A side of the fourth groove 340.

The method of fixing the wire 312 to the upper member 10 is as follows. The worker pushes the first rod-shaped portion 215 into the first groove 224, the second rod-shaped portion 216 into the second groove 227, the intermediate rod-shaped portion 214 into the third groove 228, and the fourth rod-shaped portion 339 into the fourth groove 340 from the front to receive them. At this time, the first rod-shaped portion 215 passes between the pair of first protrusions 29, the second rod-shaped portion 216 passes between the pair of second protrusions 30, the intermediate rod-shaped portion 214 passes between the pair of third protrusions 238, and the fourth rod-shaped portion 339 passes between the pair of fourth protrusions 341. As a result, the first rod-shaped portion 215 is engaged between the pair of first protrusions 29, the second rod-shaped portion 216 is engaged between the pair of second protrusions 30, the intermediate rod-shaped portion 214 is engaged between the pair of third protrusions 238, and the fourth rod-shaped portion 339 is engaged between the pair of fourth protrusions 341, so that the clip 313 is connected to the wire 312.

Next, the worker inserts the engagement portion 31 of the clip 313 connected to the wire 312 into the engagement hole 32 from the front. At this time, at the same time that the engagement portion 31 is inserted into the engagement hole 32, the fourth rod-shaped portion 339 also passes through the engagement hole 32. This fixes the clip 313 to the upper member 10.

The first groove 224 receives the first rod-shaped portion 215, the second groove 227 receives the second rod-shaped portion 216, the third groove 228 receives the intermediate rod-shaped portion 214, and the fourth groove 340 receives the fourth rod-shaped portion 339. This configuration allows the clip 313 to be stably coupled to the wire 312. Because the fourth groove 340 is formed in the engagement portion 31, there is no need to provide an elastic claw 34 on the first portion 217, simplifying the structure of the clip 313.

The clip 413 and vehicle seat 1 according to the fourth embodiment are different from the clip 13 and vehicle seat 1 according to the first embodiment in the shape of the clip 413 and the shape of the upper member 410. In the following explanation, only the different configurations will be explained, and the explanation of the same configurations as those of the clip 13 and vehicle seat 1 according to the first embodiment will be omitted by referring to the above description.

As shown in FIG. 9, the upper member 410 has a cylindrical protrusion 442 on the edge of the engagement hole 432. The protrusion 442 extends forward from the edge of the engagement hole 432. The protrusion 442 may be, for example, a burr that is generated when the engagement hole 432 is drilled from the rear side of the upper member 410 with a drill. The side wall 424B of the first portion 417 has a fifth groove 445 formed on the outer surface. The fifth groove 445 is formed in a ring shape centered on the support portion 433.

When the clip 413 is attached to the upper member 410, the protrusion 442 is received in the fifth groove 445. In this manner, the clip 413 can be fixed to the upper member 410 without interference from the protrusion 442 that is generated when the engagement hole 432 is created.

Although the specific embodiment has been described above, the present invention is not limited to the above embodiment and can be modified in a wide range of ways. For example, in the second embodiment, the first groove 224, the second groove 227, and the third groove 228 open in the same direction, and in the third embodiment, the first groove 224, the second groove 227, the third groove 228, and the fourth groove 340 open in the same direction, but each opening may open in a direction opposite to each other.
