Abstract
A hydraulic clutch includes friction plates to transmit motive power, a piston movable between (i) a pressing position, at which the piston presses the friction plates for the hydraulic clutch to be engaged to transmit motive power, and (ii) a separated position, at which the piston is spaced apart from the friction plates for the hydraulic clutch to be disengaged to block motive power, the piston being movable into the pressing position in response to receiving hydraulic fluid to move the piston toward the pressing position, and a holder to (i) hold the piston at an intermediate position between the pressing position and the separated position in response to the piston coming into contact with the holder and (ii) release the piston from the intermediate position.
