Abstract

A hydraulic clutch including a clutch drum with an outer cylinder fitted with a plurality of clutch plates and a side wall; a clutch piston that defines together with the clutch drum an engagement oil chamber, and moves in an axial direction to press the clutch plates by hydraulic pressure supplied to the engagement oil chamber; and a cancel plate that defines together with the clutch piston a cancel oil chamber that cancels centrifugal hydraulic pressure. The side wall of the clutch drum is formed with a first oil passage that radially extends and is in communication with the engagement oil chamber, and a second oil passage that radially extends and is in communication with the cancel oil chamber. One of the first and second oil passages is at least partially included in a range of an axial width of the other of the first and second oil passages.
