A wire-like member is two-folded and a pair of wire-like portions (32) is placed substantially parallel with a predetermined spacing. In the middle of one of the pair of wire-like portions (32), there is formed a projection portion (34) projecting into the direction departing away from the other wire-like portion (32). Contact portions (35) in contact with each other are formed on the heads of the wire-like portions (32). When a connection pin (3) is inserted into a through hole (23) of a piece (2), the connection pin (3) is bent on two portions, a bent portion (31) and the contact portion (35) as the fulcrums, and the projection portions (34) are engaged with the inner periphery of the through hole and stabilized when engaged with a large-diameter portion (231). Sine the connection pin (3) is constructed so as to be deformed on the two portions as the fulcrums, stress on one fulcrum is reduced, and dimensions of each portion of the pin do not change even after repeated use of the connection pin (3), resulting in a stable fixing force is obtainable. |
