Claims

[Claims for Utility Model Registration] 1. A daytent portion is provided on the cam surface of the cam that moves together with the control lever when the control lever is operated, and a casing is provided facing the cam surface, and this casing has a day tent portion. a sliding body that has a rod whose tip comes into contact with the cam surface and is movable in a direction in which the tip of the rod engages and disengages from the detent portion; A pressure chamber that applies pressure in the direction of contact with the surface, a pressure port that introduces pressure oil into this pressure chamber, and a drain port that communicates with the tank.
Engagement of the rod tip with the above detent part
A detent device for a control lever, characterized in that it is provided with a seat portion that opens and closes by movement of the sliding body due to detachment, and communicates and shuts off the pressure chamber with the drain port. 2. A sliding body is composed of a piston that moves together with the rod within the casing, and a poppet that moves in the axial direction on the outer periphery of the piston independently of the piston and in conjunction with the piston to open and close the seat part. The control lever detent device according to claim 1, characterized in that:
