A ring case includes: a main body; an engaging groove formed in the main body; and a ring-engaging body for engaging the engaging groove, and the ring-engaging body includes: a base for engaging rotatably the engaging groove, and a ring member configured to rotate with the base and engaging the base through a hinge so as to engage rotatably with the base. The ring member is fixed vertically with respect to the base. The engaging groove has a form of hollow circular band, and the base is provided with an engaging portion along an exterior circumferential surface of the base, so that the engaging portion is installed in the engaging groove. Embossing portions are formed along an exterior circumferential surface of the base, and depressed portions are formed inside the main body, so that when the base rotates the embossing portions are received into or extracted from the depressed portions. |
