To provide a fastener for fastening a first component and second component to each other and electrically insulate them from each other while maintaining the advantages of a blind nut able to fasten the first component and second component securely from one side. <??>The fastener (3) consists of a blind nut (1) and a bush (2). The blind nut (1) consists of a nut (9) with female threading (7) integrated with a tube (10) and a flange (13). The tube (10) can be deformed so as to expand the diameter of the portion inserted into a mounting hole in the first component (5) as far as the back side of the component. The bush (2) is ring-shaped and made of an insulating material so as to surround the outer periphery of the tube (10) adjacent to the flange (13). A circumferential groove (18) is formed in the periphery of the bush (2) into which edge of a mounting hole in the second component (6) is fitted and engaged. Thus, a portion of the tube (10) can be deformed to expand its diameter to interpose and support the first component (5) between the deformed portion (26) and the flange (13), so that the first and second components are connected mechanically to each other in an electrically insulated state. <IMAGE> |
