Even when a force that lifts the clip 10 obliquely upward (see arrow F4 in FIG. 5) is applied, the clip 10 can be firmly held.

  That is, since the holding hole insertion portion 41 of the columnar portion 31 of the clip 10 inserted into the fixing hole 2 is formed with a width larger than the opening width W of the communication portion 5 of the fixing hole 2, the main body portion of the clip 10. Even if a twisting force is applied to 20, since the holding hole insertion portion 41 engages with the opening periphery of the communication portion 5 of the fixing hole 2, the columnar portion 31 is prevented from coming out of the holding hole 4. The clip 10 can be held at a predetermined position against the twisting force.

  In this embodiment, the columnar portion 31 of the clip 10 is inserted into the screw hole 3 in addition to the portion inserted into the holding hole 4 of the fixing hole 2, and from the opening width W of the communicating portion 5 of the fixing hole 2. Has a screw hole insertion portion 39 formed with a large width. Therefore, when a rotational force or a twisting force is applied to the clip 10, the screw hole insertion portion 39 is engaged with the opening periphery of the communication portion 5 on the screw hole 3 side, and the opening periphery of the communication portion 5 on the holding hole 4 side. Since the holding hole insertion portion 41 is engaged with the columnar portion 31 from both the screw hole 3 side and the holding hole 4 side with respect to the opening periphery of the communicating portion 5 of the fixing hole 2, the fixing hole The clip 10 can be positioned and fixed with respect to 2 more reliably.

  Furthermore, in this embodiment, as shown in FIG. 6, the columnar portion 31 of the clip 10 has a shape that matches the shape of the opening periphery of the communicating portion 5 of the fixing hole 2 (here, screw hole insertion) Part 39 and holding hole insertion part 41), the screw hole insertion part 39 and the holding hole insertion part 41 of the columnar part 31 of the clip 10 can be firmly engaged with the opening periphery of the communication part 5 of the fixing hole 2, The clip 10 can be positioned and fixed accurately with respect to the fixing hole 2 with less backlash.

  Further, since the elastic piece portion 37 of the leg portion 30 of the clip 10 can be bent by the gap 35 and has elasticity, even if there is a dimensional error in the screw groove of the screw hole 3 or the like, the elastic piece portion The projecting portion 47 provided on 37 can be elastically engaged with the inner periphery of the screw groove of the screw hole 3, and the clip 10 can be fixed to the fixing hole 2 with less backlash.

  Furthermore, since the leg portion 30 of the clip 10 can be bent by the gap 35 as described above, for example, even if the clip 10 is molded with a fiber reinforced resin having high rigidity but poor flexibility, it is elastic. By bending the piece 37, the leg 30 can be inserted into and removed from the fixing hole 2 without damaging the protrusion 47 of the elastic piece 37, and the clip 10 can be used repeatedly.
