Abstract
A lock mechanism includes a lock shaft () attached to a first bracket (), a lock shaft support shaft (), and a biasing spring that biases the lock shaft () in a direction in which the lock shaft () abuts against a second bracket (). Rotational movement prevention stoppers (and) abut against each other, thereby preventing rotation of the first bracket () and the second bracket () in the locking direction and a backlash therebetween. The lock shaft () comes into contact with both a first side face () and a second side face (), and a pair of tangents (and) to the lock shaft () are set to form a wedge (), so that rotation of the first bracket () and the second bracket () in the locking direction and the opposite direction is prevented without backlash.
