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 fastener 1 includes a pin 10, a metal plate spring member 30 and a grommet 50. The plate spring member 30 has a base portion 31 and a pair of elastic engagement pieces 35, 35 which are opened in their free state and which are closed when pressed against their elastic restoring force. The elastic engagement pieces 35 have engagement shoulder portions 37 which are brought into engagement with the mounting hole, and distal ends thereof are folded to constitute folded portions 40. The folded portions 40 are offset widthwise from each other, and engagement projecting pieces 43 are formed on inner sides thereof. Abutment pieces 45 are formed on the folded portions 40 in positions lying closer to the base portion 31 with which a distal end portion 15 of the pin 10 is brought into abutment to impart a driving force thereto. Abutment portions 45a are formed on the abutment pieces 45 which convert the driving force applied along an inserting direction of the pin 10 into a driving force applied widthwise outwards of the abutment pieces 45. |
