PROBLEM TO BE SOLVED: To facilitate the assembly, and to solve any trouble of being hooked on a carrying conveyor by the assembly with excellent accuracy by continuously providing a pair of bearing plates in which a through hole is formed in each end part on the pivotable attachment side of a lid body, and providing a detachment regulation part to be completed by being folded on the inner bearing plate. SOLUTION: A detachment regulation part 19 integrated with an inner bearing plate 18 comprises an L-shaped fixed piece 24 which is folded inward of a side edge of the bearing plate 18, i.e., orthogonal to the direction of the turning axis, and an I-shaped projected piece 25 which is formed along the bearing plate 18, and brought close to a tip of the fixed piece 24 and holds a folded part of a shaft pin 20 when being folded orthogonal inwardly. Because the bearing plate 18, the L-shaped fixed piece 24, and the I-shaped projected piece 25 are made of steel plate, only the I-shaped projected piece 25 is held by cutting pliers, etc., and bent in the assembly. The movement in the axial direction of the folded part 22 of the shaft pin 20 is regulated by the bearing plate 18 and the L-shaped fixed piece 24, and the rotation is also regulated by the L- shaped fixed piece 24 and the I-shaped projected piece 25. |
