The invention provides a winch which can reliably stop rotation of a shaft-shaped component and can improve installation strength of a pawl shaft when a brake device breaks down and the like. A winch (10) is provided with a rotation lock device (100) for locking the rotation of a shaft-shaped member (25), and the rotation lock device (100) is provided with a stopper support member (120) that rotates integrally with the shaft-shaped member (25), a stopper member (140) that is slidably supported by the stopper support member (120), and a stopper locking mechanism (110). The locking member (114) is provided with a locking wall (114) which stops the rotation of the shaft-shaped member (25) by abutting against the stopper member (140). When the shaft-shaped member (25) is rotated at an accelerated speed in the first rotational direction, the stopper member (140) protrudes to a position where the stopper member (140) engages with the stopper locking mechanisms (110) and stops the rotation of the shaft-shaped member (25), and a pawl shaft (115) is integrally formed on each stopper locking mechanism (110), and the stopper locking mechanisms (110) are attached to the frame (12) by means of support bolts (B1).

    本发明提供一种卷扬机,在制动装置发生了故障时等,能够可靠地停止轴状构件的旋转,并且能够提高棘爪轴的安装强度;卷扬机(10)具备对轴状构件(25)的旋转进行锁定的旋转锁定装置(100),旋转锁定装置(100)具备:与轴状构件(25)呈一体地旋转的限动件支承构件(120)、以能够滑动的方式支承于限动件支承构件(120)的限动构件(140)、以及限动件卡定机构(110),其具有通过与限动构件(140)抵接而使轴状构件(25)的旋转停止的卡定壁(114);在轴状构件(25)向第一旋转方向加速旋转时,限动构件(140)向与限动件卡定机构(110)卡合的位置突出而使轴状构件(25)的旋转停止,并且,在各限动件卡定机构(110)上一体化形成有棘爪轴(115),限动件卡定机构(110)利用支撑螺栓(B 1)安装在框架(12)。
