転台持上操作装置。[Scope of Claim for Utility Model Registration] A hydraulic actuator interposed between the driver's cab and the chassis is provided with a hydraulic pipe line from a hydraulic pump driven by an electric motor, and the hydraulic pipe line includes: In the above configuration in which the hydraulic actuator is provided with a hydraulic switching valve that switches the hydraulic line in a direction in which the hydraulic actuator extends or contracts, the switching of the hydraulic switching valve is performed by each switching operation of a lever that swings around a fulcrum. The oscillating member is interlocked with the electric motor and the power source, and turns on the switch interposed between the electric motor and the power source by moving it in one direction and turning it off by returning to the other side. when the lever is operated to the one side by the first protrusion fixed to the operation grip side of the lever, centering on the fulcrum, and when the lever is operated to the other side end, the lever is operated around the fulcrum, A driver's cab lifting operating device, characterized in that the lever is operated in the one direction by a second protrusion fixed to the opposite side of the operating grip.
