  • CLIP ATTACHMENT STRUCTURE
    Publication number: 20220228618
    Abstract: A clip is attached such that a leg portion protruding downward from a head portion is inserted into a cylindrical insertion hole of an attachment-target member. The clip has a plurality of engagement protrusions protruding from the leg portion and arranged in an insertion direction. The engagement protrusions have engagement corners sharpened to have a corner radius less than 0.2 mm. At the time of insertion into the insertion hole, the engagement corners slide on an inner circumferential wall surface while the engagement protrusions are elastically deformed. After the insertion, the engagement protrusions are elastically restored to dig into the inner circumferential wall surface, thereby preventing the clip from coming off from the insertion hole.
