Abstract
A transmission device includes a first clutch and a second clutch that is disposed circumferentially inward of the first clutch so as to overlap with the first clutch as viewed from a radial direction. The first clutch includes a first clutch drum, a first clutch piston that is axially movable by hydraulic pressure supplied to a first engagement side oil chamber on an inner circumferential side of the first clutch drum, and a first cancel plate that defines together with the first clutch piston a first cancel oil chamber that cancels centrifugal hydraulic pressure. The first cancel plate is fastened between the first clutch drum and a second clutch drum of the second clutch.
