If the XYZ coordinate system of the present embodiment is applied, the grip portion 103, the base portion 105, and the hook portion 104 are arranged along the Z-axis direction. Further, the hook portion 104 of the clip 100 holds the wire 20 in the space formed between the hook portion 104 and the guide piece 106. In such a configuration, since the base 105 and the guide piece 106 are included in the dimension H of the clip 100 in the Z-axis direction, it is difficult to reduce this dimension H.
On the other hand, the skin material attachment 10 of the present embodiment has a cantilever type engaging structure, and the clip 50 is clip-locked in a state of being engaged with one side of the clip locking member 40 in the Y-axis direction. The wire 20 is held between the member 40 and the accommodation space forming surface 44, which is the surface on the negative side in the Z-axis direction. Therefore, the dimension H of the clip 50 in the Z-axis direction can be made smaller than before (see FIG. 6). As a result, the skin material attachment 10 of the present embodiment can reduce the foreign body sensation of the seated person with respect to the clip 50 even when it is used for the thin cushion material 2.

Further, the conventional clip 100 has a structure in which the clip locking member 102 is gripped from both sides in the Y-axis direction, whereas the clip 50 of the present embodiment engages with one side of the clip locking member 40 in the Y-axis direction.

Therefore, in the present embodiment, not only the dimension of the clip 50 in the Z-axis direction but also the dimension of the clip 50 in the Y-axis direction can be made smaller than that of the conventional clip 100.

Further, in the present embodiment, the clip 50 has a pair of elastic claw portions 52A and 52B, the clip locking member 40 has a plurality of groove portions 416, and the elastic claw portions 52A and 52B have an arbitrary one groove portion 416. Since the above-mentioned engagement structure is realized by inserting the clip 50 into the clip, the engagement position of the clip 50 with respect to the clip locking member 40 can be adjusted in the X-axis direction.

Since the clip 50 of the present embodiment has a cantilever type engaging structure as described above, when the clip 50 engages with the wire 20, the Y-axis direction and the Z-axis are centered on the first engaging portion 52. A rotational moment having a component in the direction is likely to occur. However, in the present embodiment, the rotation of the clip 50 due to the moment can be suppressed by engaging the second engaging portion 53 of the clip 50 with the second engaged portion 42 of the clip locking member 40. Further, in the present embodiment, the engagement between the second engaging portion 53 and the second engaged portion 42 for suppressing the rotation of the clip 50 is realized by a simple configuration.

In the skin material attachment 10 of the present embodiment, the clip locking member 40 and the hook portion 54 each have wire stoppers 45 and 542 that can come into contact with the wires 20 accommodated in the accommodation space 21, respectively. It is possible to preferably prevent the wire 20 from falling off from the hook portion 54.

In the skin material attachment 10 of the present embodiment, since the clip locking member 40 has a guide surface 43 that guides the wire 20 in contact with the guide surface 43 toward the hook portion 54, the clip 50 is attached to the wire 20. Easy to operate.
