路。[Claim for Utility Model Registration] One displacement chamber of the hydraulic actuator that operates the engagement and disengagement of the clutch is configured to be able to selectively communicate with a high hydraulic pressure pipe or a reservoir by switching a hydraulic switching valve. The other displacement chamber of the hydraulic actuator communicates with a low hydraulic pressure pipe whose hydraulic pressure is regulated by a pressure setting valve, and between the high hydraulic pressure pipe and the low hydraulic pressure pipe, there is a connection between the high hydraulic pressure pipe and the low hydraulic pressure pipe. In a configuration in which a hydraulic pressure regulating valve for controlling the hydraulic pressure in the pipeline is provided, the displacement volume of the high hydraulic pressure pipeline is controlled so that the hydraulic pressure of the high hydraulic pressure pipeline becomes a specified hydraulic pressure. A discharge pipe of a variable displacement hydraulic vane pump is connected to the discharge pipe of the variable displacement hydraulic vane pump, and a throttle flow passage is connected between the high hydraulic pressure pipe and the low hydraulic pressure pipe, and the hydraulic pressure in the low hydraulic pressure pipe is transferred to the discharge pipe of the variable displacement hydraulic vane pump. The clutch hydraulic control circuit is installed on the back of the.
