    • A locking device of a rotary shaft includes a clutch member rotating integrally with the rotary shaft and provided so as to be displaceable in the direction of axis of the rotary shaft, a locking member provided in a fixed state to engage the clutch member to regulate the rotation of the clutch member, a biasing member biasing the clutch member toward the locking member, and a torque transmission member rotating under the rotary torque transmitted thereto from a power source, having a boss loosely inserted into a cam groove provided in an outer peripheral portion of the clutch member, and transmitting the rotary torque to the clutch member via the boss. The boss is displaced within the cam groove with switching of the rotation/stop of the torque transmission member or switching of the rotational direction thereof.
    • 旋转轴的锁定装置包括离合器构件,其与旋转轴一体地旋转并且设置成可以在旋转轴的轴线方向上移位;锁定构件,其设置在固定状态以与离合器构件接合,以调节 离合器构件的旋转,将离合器构件朝向锁定构件偏置的施力构件,以及在从动力源传递到其的旋转力矩下旋转的转矩传递构件,具有松动地插入设置在外周部的凸轮槽中的凸台 并且经由凸台将旋转扭矩传递到离合器构件。 在转矩传递部件的转动/停止或其转动方向切换的情况下,凸轮在凸轮槽内移位。
