Ribs 20 stand upright on the front wall portion 16 and the rear wall portion 17, and the front and rear surfaces of the bracket 21 are supported by inserting the bracket 21 between the ribs 20. On the other hand, the left and right side wall portions 18 and 19
Abuts on the left and right end faces 22 of the bracket 21 inserted between the ribs 20. The displacement of the bracket 21 in the width direction is restricted by this contact. In such a structure, since the front and rear surfaces and the left and right end surfaces 22 of the bracket 21 are fixed, there is no relative displacement between the bracket 21 and the clip 14, and a stable assembly state can be achieved.

In the center of the front wall 16 of the locking frame 15, a slit 24 is formed in a longitudinal direction as shown in FIG. 4, and a flexible lip 23 is arranged in the slit 24. The flexible lip 23 has a plate shape extending upward in the slit 24, and can elastically bend in the front-rear direction of the locking frame 15. On the rear surface of the flexible lip 23, a locking projection 25 that engages with the bracket 21 is protruded.

Further, an easily breakable portion 26 is formed on the right side wall portion 19 of the left and right side wall portions 18 and 19 of the locking frame 15. The easily breakable portion 26 is formed by thinning the root portion of the right side wall portion 19, and is easily broken by an impact or the like acting in the thickness direction on the right side wall portion 19. I have. Even when such an easily breakable portion 26 is formed, the easily breakable portion 26 is not destroyed by a force in the longitudinal direction of the locking frame 15, that is, in the vertical direction, and the clip 14 is attached to the bracket 21.
It is possible to securely fix it.

The bracket 21 is erected from a vehicle body (not shown) as a support member. The bracket 21 has a long plate shape, and as shown in FIGS. 5 and 6, a locking hole 27 with which the locking projection 25 of the clip 14 is engaged is formed at an upper portion thereof. The locking hole 27 and the locking projection 25
Is engaged with the clip 14 so that the bracket 2
