Claims

[Scope of Claim for Utility Model Registration] A rotating opening/closing body that closes an opening formed in an article storage main body, a rotating shaft protruding from both ends of the opening/closing body and integrally formed with the opening/closing body; A cam member provided coaxially with the rotating shaft, and a long hole for movably supporting the rotating shaft in a direction parallel to the plane of the opening/closing body in the closed state and perpendicular to the rotating shaft. and a bearing member provided with a standing wall that is arranged adjacent to the cam member on the outer circumferential side of the opening and that comes into contact with the cam member when the opening/closing body is opened to move the rotating shaft toward the inner side of the opening; A shaft structure of a rotary opening/closing body, comprising a biasing means for pressing the member toward a vertical wall.
