PROBLEM TO BE SOLVED: To provide a hydraulic clutch which is simple in structure, high in a degree of freedom of design, can dispense with a mechanism for eliminating an influence of centrifugal hydraulic pressure, and is stabilized in the operation of a piston.SOLUTION: In a hydraulic clutch 10, a hydraulic chamber 14 is formed so that an inside diameter wall part 16a of a clutch drum 16 and an intermediate part 16c continuing to the inside diameter wall part are outwardly bulged so as to form a U-shape that a radial cross section of the intermediate part is inwardly opened in the axial direction, a piston 13 which is formed conforming to a shape of the hydraulic chamber 14 is embedded into the hydraulic chamber 14, a force transmission member 13a is integrally connected to an end part of the piston 13 at the outside of the radial direction, and at a side opposite to the hydraulic chamber 14 of the piston 13, and has a disc spring 11 which energizes the force transmission member 13a and the piston 13 to the direction of the hydraulic chamber 14, and thus there can be obtained the hydraulic clutch which is simple in structure, and does not need a canceller mechanism and a check valve. |
