Provided is a displacement suppression device for a lifting body of an elevator in which a guide rail does not easily deflect due to a reaction force applied to the lifting body. A stopper unit (22) of the displacement suppression device (18) is provided to the vertically moving body. The stopper unit (22) is provided with a stopper (26), a first drive unit (27), and a second drive unit (28). The stopper (26) faces a guide rail that guides the vertically moving body. The first drive unit (27) moves the relative position of the stopper (26) with respect to the vertically movable body in the travel direction of the vertically movable body. The first drive unit (27) causes the stopper (26) to face the restraining unit (13) of the guide rail. The second drive unit (28) changes the gap between the guide rail and the stopper (26) by moving the stopper (26). The second drive unit (28) suppresses the displacement of the vertically moving body by means of a stopper (26) in which the gap between the second drive unit (28) and the restraint unit (13) of the guide rail is reduced.
提供导轨不易由于从升降体受到的反作用力而产生挠曲的电梯的升降体的位移抑制装置。位移抑制装置(18)的止动单元(22)设置于升降体。止动单元(22)具备止动件(26)、第1驱动部(27)以及第2驱动部(28)。止动件(26)与引导升降体的导轨对置。第1驱动部(27)使止动件(26)相对于升降体的相对位置沿升降体的行驶方向移动。第1驱动部(27)使止动件(26)与导轨的约束部(13)对置。第2驱动部(28)通过使止动件(26)移动来改变导轨与止动件(26)之间的间隙。第2驱动部(28)利用缩小了与导轨的约束部(13)之间的间隙后的止动件(26)来抑制升降体的位移。
