As a result, four elastic protrusions 81 to 82 are caught by the rear surface of the panel 40, and the assist grip 20 is inserted into the two panel holes 41 of the panel 40 through the attachment device 10. It is temporarily fixed.

Finally, the pin 60 is deeply inserted into each insertion hole 90 of the two grommets 50 to 51. This prevents the four elastic protrusions 81 to 82 from bending toward the insertion hole 90.

As a result, the two grommets 50 to 51 do not fall out of each panel hole 41 of the panel 40, and the assist grip 20 is connected to the two panel holes 41 of the panel 40 through the attachment device 10. It is fixed to).

The assist grip 20 may be attached last.

On the other hand, when removing the assist grip 20, although not shown, the pin 60 is removed from the two grommets 50 to 51 using a flat-blade screwdriver.

Next, although not shown, the two elastic projections 81 are pulled out by pulling the two release pieces 83 using a tool such as a radio pliers through the insertion holes 90 of the two grommets 50 to 51. It is bent toward the insertion hole (90).

Then, the assist grip 20 and the interior material 30 can be removed from the panel 40 by removing the cylindrical portion 80 from the two panel holes 41 of the panel 40.
