A cam that moves together with the control lever when the control lever is operated, a piston that is provided on a fixed part so that its tip comes into sliding contact with the cam as the cam moves, and this piston. The cam includes a pressure chamber formed behind the pressure chamber, and a spring provided in the pressure chamber to press the piston toward the cam, and the cam has a part of the surface in sliding contact with the tip of the piston. A detent part is provided which has a larger sliding resistance with the tip of the piston than the other parts, and a sensor detects contact and separation of the hand from the control lever, and hydraulic pressure is applied to the pressure chamber based on the separation signal from this sensor. A control lever daytent device, characterized in that it is provided with hydraulic pressure supply means for supplying. 2. The control lever detent device according to claim 1, wherein the sensor for detecting contact and separation of the hand with respect to the control lever is a pressure-sensitive sensor provided in the grip of the control lever. 3. The control lever detent device according to claim 1, wherein the sensor that detects contact and separation of the hand with respect to the control lever is a strain gauge that detects deflection of the lever.
