Clip

A clip comprising:

• a grommet having a projecting portion, and a plurality of leg portions diametrically expandably extending from the projecting portion;
• and
• a shaft member including a head portion, and a shaft portion extending from the head portion, and being configured to be inserted into an inside of the leg portions from a through hole provided in the projecting portion so as to expand a diameter of the leg portions,
• wherein the clip is configured to be switchable between a lock position where the shaft member is pushed into the grommet for a predetermined amount to expand the diameter of the leg portions, and an unlock position where the shaft member is further pushed in so as to return the leg portions to an original condition,
• each leg portion includes a leg-side convex portion provided on an inner side of the plurality of leg portions;
• a convex-portion wall face extending from a leg-portion tip side to the leg-side convex portion;
• and a guide portion situated adjacent to the leg-side convex portion and extending to the leg-portion tip side, the guide portion having an extending tip inclined to the inside of the leg portion for easily inserting into an attachment hole for insertion of the leg portion,
• the shaft portion includes a shaft-side convex portion engaging the leg-side convex portion to expand the diameter of the leg portion;
• a concave portion provided between the shaft-side convex portion and the head portion, the concave portion, when engaging the leg-side convex portion, returning the leg portion to the original condition from expansion thereof;
• an abutment portion provided between the shaft-side convex portion and the concave portion for the convex-portion wall face;
• and a release portion for the guide portion, and
• the shaft member includes an elastic piece provided in the shaft portion, and having a fitting state of fitting into an edge portion of the through hole on a projecting portion side in an engagement state between the leg-side convex portion and the shaft-side convex portion, and when the shaft member is pushed into the grommet further, the shaft member is adapted to pass the through hole accompanied by an elastic deformation to release the fitting of the fitting state.
