The claw parts 14, 14 are provided with a step surface 16 at the upper end thereof, which faces the back surface of the contact part 13 with a gap corresponding to the thickness of the floor panel 1.
It gradually becomes narrower towards the outside of the car. The width of both claws 14, 14 at the step surfaces 16, 16 is wider than the short axis length of the elongated hole 12 in a free state (in a state where both claws 14, 14 are not bent in opposite directions); Both stepped surfaces 16, 16 are adapted to engage with the circumferential edge of the elongated hole 12 on the outside of the vehicle. Also,
Guide pieces 17, 17 protrude from both side surfaces of both claw parts 14, 14 to opposite sides, and both guide pieces 17,
The distance between the tips of the holes 17 is comparable to the length of the long axis of the elongated hole 12, and when the claws 14, 14 are inserted into the elongated hole 12, the claws 14, 14 are located at approximately the center of the elongated hole 12. It is now designed to guide you. Further, the extension part 15 has a cylindrical shape and has a slit 1 extending in its longitudinal direction.
8 is formed, and an internal thread is cut therein extending from the extension part 15 to the abutting part 13.

The guide member 11 of the interior material 6 extends downward from around the screw insertion hole 19, and the opening is aligned in the interior material installation direction M.
As shown in FIG. 4, the inner diameter of the U-shaped base is comparable to the outer diameter of the extension 15 of the grommet 10, and the width of the opening widens toward the tip. Guide surfaces 20, 20 are formed. Further, an engaging portion 21 that protrudes downward and engages with the upper edge corner portion of the contact portion 13 is provided at the tip of the lower edge of the guide member 11.
