Abstract
A hinge includes first hinge connectors having first shaft holes drilled and which are disposed at a rear of a synthetic resin case body that may contain a cosmetic material; a second hinge connector having a second shaft hole drilled and which is disposed at a rear of a synthetic resin lid that opens or closes with respect to the case body. The hinge also includes synthetic resin hinge shafts inserted through the first shaft holes, the second shaft hole, and two protruded fitting parts with a shape of a short cylinder disposed so as to project from end faces of the first hinge connectors and come in abutment with two U-shaped, recessed fitting parts disposed on end faces of the second hinge connector. The recessed fitting parts have an opening to a front side the lid, the opening having a width substantially equal to a diameter of the protruded fitting parts, the recessed fitting parts having a center of curvature that corresponds to a center of the second shaft hole and have a radius of curvature of substantially the same radius of curvature the protruded fitting parts. The hinge prevents shearing forces from acting on the hinge shafts and protects the hinge shafts against shearing fracture.
