Abstract
There is provided a fastener which can be brought into firm engagement with a mounting hole without being affected by a change in thickness of a member in which the mounting hole is provided or a larger or smaller inside diameter of the mounting hole. This fastenerincludes a pin, a metal plate spring memberand a grommet. The plate spring memberhas a base portionand a pair of elastic engagement pieceswhich are opened in their free state and which are closed when pressed against their elastic restoring force. The elastic engagement pieceshave engagement shoulder portionswhich are brought into engagement with the mounting hole, and distal ends thereof are folded to constitute folded portions. The folded portionsare offset widthwise from each other, and engagement projecting piecesare formed on inner sides thereof. Abutment piecesare formed on the folded portionsin positions lying closer to the base portionwith which a distal end portionof the pinis brought into abutment to impart a driving force thereto. Abutment portionsare formed on the abutment pieceswhich convert the driving force applied along an inserting direction of the pininto a driving force applied widthwise outwards of the abutment pieces
