Claims

[Scope of utility model registration request]

A power piston that operates a clutch lever, a first communication passage that communicates a back pressure chamber of the power piston with a pressure source, and opening/closing control of the first communication passage that is driven and controlled by the operating pressure of a clutch mask cylinder. In a clutch operating device equipped with a clutch booster comprising a valve mechanism that performs
a second communication passage communicating between the back pressure chamber of the power piston and the pressure source; opening/closing control of the first communication passage between the valve mechanism and the back pressure chamber of the power piston; and the second communication passage.
and a solenoid valve for controlling the opening and closing of a communication passage of the power piston, and controlling the supply of pressure from the pressure source to the back pressure chamber of the power piston to drive and control the power piston and control the clutch lever.
a first pressure supply control system comprising the valve mechanism, the solenoid valve, and a first communication path;
A clutch operating device comprising at least two systems, the solenoid valve and a second pressure supply control system comprising a second communication path.
