The fixed case 137 rotatably fixes the lock bar 136. Specifically, an insertion hole is formed in the fixing case 137 in the horizontal direction, and the first bar 136a of the lock bar 136 is inserted into the insertion hole. In addition, a fastening hole 137a is formed in the fixed case 137 in the vertical direction. The bolt 13 is fastened to this fastening hole 137a. Here, the bolt 13 fastened to the fastening hole 137a of the fixing case 137 serves to prevent rotation of the first bar 136a. That is, after the locking unit 130 is set to the lock mode, rotation of the lock bar 136 in the second direction must be prevented to keep the lock mode stable. Therefore, the bolt 13 fastened to the fastening hole 137a presses the outer circumferential surface of the first bar 136a to prevent its rotation. When the lock unit 130 is to be changed from the lock mode to the unlock mode, the bolt 13 holding the outer circumferential surface of the first bar 136a is released. In this case, the first bar 136a may be freely rotated, so that the second bar 136b of the locking bar 136 is separated from the recess 134 of the second plate 133. Can be rotated.
