• a clutch cylinder;
• a depressing force transmission mechanism configured to transmit a depressing force, with which the clutch pedal is depressed, to the clutch cylinder;
• and
• an actuator configured to generate power for connecting and disconnecting the clutch through the depressing force transmission mechanism, wherein:
• the depressing force transmission mechanism includes a separation mechanism that connects and disconnects a depressing force transmission path of the depressing force transmission mechanism;
• the separation mechanism includes
• an input piston to which the depressing force from the clutch pedal is input,
• an output piston that outputs a clutch operating hydraulic pressure to the clutch cylinder,
• a first oil chamber provided between the input piston and the output piston, and
• an electromagnetic valve provided to make a connection or disconnection between the first oil chamber and a reservoir tank connected to the first oil chamber;
• and
• the actuator is connected to transmit power to the output piston of the separation mechanism.
