An acceleration/deceleration mechanism is installed for a lid body rotatably supported on a main body. The mechanism includes a biasing device for forcing the lid body toward an open direction, a locking device for maintaining a closed state of the lid body relative to the main body in opposition to the force of the biasing device, and an acceleration/deceleration device 66 situated between the lid body and the main body. The acceleration/deceleration device 66 increases a speed of opening of the lid body at less than a prescribed angle r of opening of the lid body, and decreasing the speed of opening in excess of the prescribed angle r of opening. |
