Claims

[Scope of utility model registration request]

a fluid pressure actuator for connecting and disconnecting a clutch between an engine and a transmission of a vehicle; a normally closed first solenoid valve capable of connecting a fluid pressure chamber of the fluid pressure actuator to a high pressure fluid source; A normally closed second solenoid valve that can open the fluid pressure chamber to the low pressure side by opening and closing the valve, a normally open solenoid valve that can shut off the fluid pressure chamber from the low pressure side, and the clutch facing in the joining direction. and a clutch control means for controlling each of the solenoid valves to be displaced in an arbitrary manner over time.
