PROBLEM TO BE SOLVED: To provide a power transmission mechanism and a locking/unlocking device capable of reducing manufacturing cost, the number of start and stop operations, operating time, and normal/inverse rotation switching frequency without using a detection sensor.SOLUTION: A power transmission mechanism 11 comprises: a central axis 59; a driving member (61) rotary-driven around the central axis 59; a follower member (63) rotatably supported on the central axis 59; transmission members (65, 67) for transmitting the normal/inverse rotation of the driving member (61) to the follower member (63) by being supported by the follower member (63) and locked to the driving member (61); and a transmission release member (69) supported by the follower member (63) such that it freely rocks, rocked at a predetermined rotating angle of the follower member (63), and releasing the transmission of rotation from the driving member (61) to the follower member (63) by the transmission members (65, 67). |
