Claims

[Scope of utility model registration request]

In a driver's cab in which the upper window can be moved to the upper part of the driver's cabin, a stopper having an engagement hole and an inclined surface is attached to the rear side of the interior of the driver's cab, and the latch is slid inside the case of the latch attached to the upper window. A locking position of a lever fixed to a lock pin biased in the protruding direction is formed in the case, and the protrusion amount of the lock pin is set in two stages, so that when the upper window is opened and fixed, the tip of the lock pin is fixed to the stop. The upper window is guided into the engagement hole along the slope of the metal fitting, and when the lock pin and the engagement hole match, the lock pin plunges into the engagement hole and automatically fixes the upper window. Driver's cabin.
