PURPOSE: To simplify structure by rotatably supporting an operating member locking or releasing door locking, fitting a bush with a place display member into the shaft hole of the operating member and observing the state of release from the outside. CONSTITUTION: When an operating section 17b is operated in the direction of the arrow, the operating section 17b is placed at an unoperated position (a) (the state of the release of locking) projected from the wall 9 of a main body 1. The operating section is worked in the opposite direction, the operating section is placed at an operating position (the state of locking) stored in the main body 1. A place display member 27 is set up integrally on the wall surface side orthogonal to the axis X of a hinge pin 23 in a door lock knob 17 while the member 27 is formed of a bush 29 and a colored display section 31 extended from the bush 29. When the knob 17 is operated at the position (a), the display section 31 is projected from the main body 1, and the state of the release of locking is observed by eyes. Accordingly, the release of locking can be confirmed easily, and the falling-off of the display member can be prevented, and the number of parts can be decreased. |
