A rivet (R) includes a sleeve (20), which has a flange (25), and a core member (10), which is inserted into the sleeve (20). The distal end of the sleeve (20) is coupled to a plurality of pivoting pieces (30) via thin hinges (28). By inserting the core member (10) into the sleeve (20), each pivoting piece (30) is pushed against the core member (10) to pivot outward, and a laminated member (40), which is located between the flange (25) and each pivoting piece (30), is fixed. A projection (32) is arranged on the basal end surface (31) of each pivoting piece (30). A hook portion (16) is arranged on the head (15) of the core member (10) to project radially outward of the core member (10). When the core member (10) is inserted into the sleeve (20), the hook portion (16) of the core member (10) moves past the projection (32) of each pivoting piece (30) in an outwardly pivoted state to fix the pivoting piece (30). |
