An automatic transmission includes a starting clutch which connects and disconnects motive power between an engine and a transmission mechanism. The starting clutch includes a clutch hub connected to the engine, a clutch drum connected to the transmission mechanism, a friction plate provided between the clutch hub and the clutch drum, and a piston which presses the friction plate. The clutch drum has a radial-direction portion extending from an end portion of the outer-side cylindrical portion on a first axial-direction side to the radial-direction inner side, and an annular oil dam member extending from an end portion of the outer-side cylindrical portion on a second axial-direction side to the radial-direction inner side to immerse the friction plate in oil supplied from the radial-direction inner side toward the outer side, together with the outer-side cylindrical portion and the radial-direction portion.
