<p>A linear member is bent in two, and a pair of linear parts (32) is disposed substantially parallel with a specific distance. Also, a protrusion (34) is formed in the middle of one linear part (32) to protrude in a direction away from the other linear part (32), and contact parts (35) in contact with each other are formed at the distal ends. When a connecting pin (3) is inserted via the through-holes (23) of the blocks (2), the connecting pin (3) flexes with the curved parts (31) and the contact parts (35) as two fulcra, and the protrusion (34) interlocks with the inner peripheries of the through-holes (23), and then interlocks and stabilizes in a large-diameter region (231). Since the connecting pin (3) is configured so as to deform with two locations as fulcra, the stress applied to one fulcrum is reduced, and a stable fixing force can be obtained without deforming the dimensions of the components even if the connecting pin (3) is used repeatedly. <IMAGE></p> |
