Fastening structure for part and clip used therein

摘要

A fastening member has a head part, a shaft part, a thinly formed flange extending in a straight shape from an outer perimeter of the head part, and a coupling device (for example, head part of a grommet). A part has a through-hole, and a wall part positioned on an outer perimeter of the through hole and extending toward the direction of insertion of the shaft part. A base has an installation hole allowing insertion of the shaft part. When the base and the part are bound by insertion of the shaft part, the flange is pressed against the wall part and becomes in a bent-back state.
