The invention provides a rope anti-falling device of an elevator. The rope anti-falling device can shorten the time for adjusting the size of a gap between a rope and each anti-falling component. In the rope anti-falling device of the elevator, a pinion gear (83) can rotate relative to a main shaft (43) by taking the axis of a driving rope wheel (42) as the center. The first retaining mechanism section (81) and the second retaining mechanism section (82) each have a rack (85) that meshes with the pinion gear (83) and a retaining member (86) that is attached to the rack (85). In the first retaining mechanism section (81) and the second retaining mechanism section (82), the rack (85) and the retaining member (86) move together with the rotation of the pinion gear (83) relative to the main shaft (43), and the size of the gap between the rope (5) and the retaining member (86) changes.

    本公开提供一种电梯的绳索防脱装置,其能够缩短对绳索与各防脱部件之间的间隙的尺寸进行调整的作业所花费的时间。在电梯的绳索防脱装置中,小齿轮(83)能够以驱动绳轮(42)的轴线为中心相对于主轴(43)旋转。第一防脱机构部(81)和第二防脱机构部(82)分别具有与小齿轮(83)啮合的齿条(85)和安装于齿条(85)的防脱部件(86)。在第一防脱机构部(81)和第二防脱机构部(82)中,齿条(85)与防脱部件(86)一起随着小齿轮(83)的旋转而相对于主轴(43)移动,从而绳索(5)与防脱部件(86)之间的间隙的尺寸发生变化。
