装置。[Scope of Claim for Utility Model Registration] In a working vehicle having a working device provided on the vehicle body and a vehicle body support device for supporting the vehicle body during work, a device for controlling the safe operation of these devices, , an operation selection means for selectively permitting the operation of the work device and the vehicle body support device; a storage detection device for detecting whether the work device is in a retracted state or a non-retracted state; and the vehicle body support device a vehicle body support detection means for detecting whether the vehicle body is in a vehicle body support state or a vehicle body non-support state; and when the storage state is detected by the storage detection means and the vehicle body non-support state is detected by the vehicle body support detection means; , the operation selection means allows the operation of the vehicle body support device and prohibits the operation of the working device, the storage state is detected by the storage detection means, and the vehicle body support state is detected by the vehicle body support detection means. When the operation selection means selects both the working device and the vehicle body support device to make them operable, the storage detection device detects the non-storage state, and the vehicle body support detection device selects the vehicle body support state. A safe operation control device for a work vehicle, comprising: a safety operation control means for prohibiting the operation of the vehicle body support device by the operation selection means and allowing operation of the work device when the operation selection means is detected.
