Claims

[Claims for Utility Model Registration] 1. In a tailgate device for a garbage collection vehicle, in which the upper end of the tailgate is pivotally attached to the opening of the body by a pivot, and the tailgate can be opened and closed, one of the body and the tailgate: A stop member is fixed in an arc shape surrounding the pivot shaft, a lock pin is supported on the other side of the body and the tailgate so as to be slidable in the radial direction of the arc-shaped stop member, and the lock pin is elastically attached to the stop member. An elastic device is provided to bias the tip of the lock pin against the stop member,
The surface of the stop member that the locking pin comes into contact with has a portion corresponding to the angular range from the tailgate closed position to the predetermined angular open position of the tailgate when the tailgate rotates around the pivot axis.
A high part that becomes higher toward the lock pin is formed, a lower part is formed in a part corresponding to a larger angular range, a stop step is formed between the higher part and the lower part, and the lock pin is placed on the surface of the lower part. The tailgate is prevented from lowering when it comes into contact with the lock pin and the stop step, and the lock pin is connected to a retraction drive device that moves the tailgate to a position retracted from the higher part of the stop member. A tailgate device comprising means for operating a reverse drive device only when a tailgate lowering device is operated. 2. Utility model registration claim 1, in which the retraction drive device is constituted by a rotational drive source, an arm that is rotated in the lock pin retraction direction by the rotational drive source, and a link that connects the tip of the arm to the rear end of the lock pin. tailgate device for garbage collection vehicles. 3. The tailgate device for a garbage collection vehicle as set forth in claim 1, wherein the elastic device is a coil spring connected to the arm.
