<p>The present invention relates to a lock device (20) of an output shaft (10), wherein the output shaft (10) is formed by connection of a driving shaft (11) and a driven shaft. The lock device (20) comprises a play angle for not transmitting power for a specified angle in mutual rotating directions formed in the connection area for connecting the driving shaft (11) and driven shaft; a locking mechanism (31, 33), provided at the driven shaft side, for locking by moving a lock member (31) arrested on the driven shaft and held movably inward and outward in the radial direction; and an unlocking mechanism (29, 30), provided on the driving shaft (11), for unlocking by moving the lock member (31) of the locking mechanism (31, 33) in an unlocking direction within the rotating amount of the play angle. <IMAGE></p> |
