PURPOSE:To obtain a thin driving shoe and increase the elevation quantity of a lid by setting the elevation guide groove of the driving shoe with which the lid is engaged through a link member so that the turning center of the link member differs in case of tilt-up and tilt-down of the lid. CONSTITUTION:When a driving shoe 46 driven forward, the second driving pin 50B falls down into the fall-down part 47D of an elevation guide mechanism 47, and rises along the first inclination part 47B, an the second link member 50 turns counterclockwise around the first driving pin 50A. Then, the first link member 44 supported onto a rear shoe 42 turns clockwise, and a lid 30 is titled up. When the driving shoe 46 is driven rearward, the driving pin 50A rises along the second inclination part 47E, and the second link member 50 turns clockwise around the second driving pin 50B. Therefore, the first link member 44 turns counterclockwise around the pin 42B, and the lid 30 is titled down.
