Claims

[Scope of utility model registration request]

A first piston that connects and disconnects the clutch and a second piston that limits the hydraulic fluid chamber are slidably housed in a hydraulic fluid chamber provided in the cylinder, and the first piston is slidably housed in a hydraulic fluid chamber that is connected to the hydraulic fluid chamber. A push rod is housed in the second piston to cause a displacement in the clutch disengaging direction, and the second piston opens and closes the hydraulic fluid chamber and the oil storage chamber through the second piston, and the second piston opens and closes the hydraulic fluid chamber and the oil storage chamber through the second piston. An on-off valve for connecting and disengaging the clutch is provided, and an oil supply tank is connected to the oil storage chamber, and an elastic member and an elastic member, which communicates with the tank and is adjacent to the oil storage chamber, are provided. A piston storage chamber that accommodates a pressure piston that is elastically pressed,
A through hole is bored along the axis of the pressurizing piston, and a recess is provided that communicates with the through hole and faces the oil storage chamber, and only the oil flows from the tank side to the oil storage chamber within the recess. A clutch actuating device comprising an oil pressurizing mechanism housing a check valve made of a float for opening a through hole.
