ABSTRACT:
A holder of the present invention is formed of a leg portion having an opening at an upper portion thereof; a flange extending outwardly from a vicinity of the opening; outer pawls projecting from the leg portion to sandwich a peripheral edge of a fitting hole together with the flange therebetween; and thick frame portions. When the leg portion of the holder is inserted into the fitting hole, the outer pawls are resiliently deformed toward depressed portions of the leg portion. When an impact is applied to the holder, abutting surfaces of the outer pawls are strongly pressed against the peripheral edge of the fitting hole. However, side surfaces of the frame portions are pressed against the peripheral edge of the fitting hole to prevent damage of the outer pawls. Thus, the holder having a reduced inserting force and improved impact resistance can be obtained.
