PROBLEM TO BE SOLVED: To miniaturize a constitution for, when downward turning a top plate, slowly moving it to a horizontal attitude and, when upward turning the top plate, raising the top plate by a light force. SOLUTION: One end part of a link rod 5 and a cam body 15 are turnably pivoted inside a storage case 16 fixed to the side of a moving body via a support shaft 24, a receiving body 20 disposed in a recess of the storage case 16 is made to abut on the cam surface of the cam body, and the cam body is constantly pushed by a compression spring 21a. The other side end of the link rod 5 is pivoted to the side of the top plate and so connected that the moving body moves to the front/rear by being associated with the upward/downward turning of the top plate.
