Abstract
Abstract A hinge-type lid mounting device has a main body to be attached to a case or the like, and the main body has at its one end a cam body pivotally mounted through a first pin. The other end of the main body defines a fixed spring seat, and a spring is interposed between the fixed spring seat and a movable spring seat adapted to abut the cam body. A lid supporting member is rotatably mounted on the cam body through a second pin perpendicular to the first pin. A lid is anchored at its one end to the lid supporting member through a lid anchoring member and a fixing screw.
