A lid opening/closing mechanism includes an arm, an arc-shaped gear, a first fixed gear, a damper, a second fixed gear, and a tension spring. The arm is disposed integrally to project from the lid to swing about a swing center as the lid opens and closes. The arc-shaped gear is formed in the arm. The first fixed gear is disposed in the body, and meshes with the arc-shaped gear. The damper is disposed in the arm, and includes a damper gear. The second fixed gear is disposed in the body, is formed along a movement locus of the damper moving as the lid moves to open and close, and meshes with the damper gear. The tension spring is disposed between the body and the arc-shaped gear to urge the lid in an opening direction.

A piece of furniture includes a furniture body with an upper floor, a flap, and least one flap fitting arranged on the upper floor in order to hold the flap movably between a position closing a storage space of the furniture body and an opening position. The flap fitting includes a housing, on which a support arm is rotatably mounted, which includes a retaining element for fixing the flap, and an energy store for applying a force to the support arm. A damper is provided for braking a movement of the support arm in the closing direction shortly before the closing position is reached. The damper can be moved via an actuating element mounted in the housing and the support arm can be braked via the actuating element when the flap is moved in the closing direction shortly before reaching the closing position.

Proposed is a door hinge that includes an arm installed on a door, a housing installed in a main body of a mechanism provided with a door and connected to the arm by a hinge shaft, a damper casing connected to the arm inside the housing by the hinge shaft and having one surface supported by a support portion of the housing, a pair of main links connected to the arm inside the housing by a link shaft to linearly move, a main spring assembly including a spring lever and a main spring inserted into the spring lever, and a damper provided inside the damper casing and moving along the periphery of the arm.
