Hinge structure and hinge structure of terminal cap

摘要

A hinge structure 5 has a bendable thin-walled plate-like hinge 11 and a rigid portion 12 continuing from this hinge 11 and formed with a large wall thickness. The hinge 11 is constituted by a plurality of hinge rows 11a to 11c. In addition, the rigid portion 12 is also constituted by a plurality of rigid portion rows 12a to 12b. The number of the hinge rows 11a to 11c is set to a number which is more numerous by one than the number of the rigid portion rows 12a and 12b. The hinge rows 11a to 11c are arranged such that the rigid portion rows 12a and 12b are each interposed between each of the hinge rows 11 a to 11c. The hinge rows 11a to 11 c and the rigid portion rows 12a and 12b are arranged parallel to each other and parallel to an outer surface of a side wall 7 on the left side.
