To simplify a whole structure and to increase a degree of freedom in designing of a driving member 33.SOLUTION: It comprises the driving member 33 rotatably driven by a driving motor 31 and a chain 34 the tip of which is connected to the movable side of the lower end of a link mechanism 20 and is wound on the driving member 33, and the driving member 33 increases an effective radius R toward the winding direction of the chain 34, and forms the length of the outer periphery to wind up the chain 34 longer than the length of the chain 34 corresponding to the elevating stroke of the link mechanism 20.SELECTED DRAWING: Figure 1
【課題】全体構成を簡単にし、駆動部材33の設計自由度を大きくする。【解決手段】駆動モータ31によって回転駆動する駆動部材33と、リンク機構20の下端の可動側に先端を連結して駆動部材33上に巻き取るチェーン34とを備え、駆動部材33は、チェーン34の巻取方向に向けて有効半径Rを増加させ、チェーン34を巻き取る外周の長さをリンク機構20の昇降ストローク相当のチェーン34の長さ以上に形成する。【選択図】図1
