A friction engagement device includes a rotating shaft, first friction plates that rotate with the rotating shaft, second friction plates arranged to face the first friction plates, an oil chamber supplied with hydraulic fluid, a piston movably provided between engagement and release positions, and first and second return springs. Ihe piston is pressed toward the engagement position by hydraulic pressure of the oil chamber. The first return spring contacts the piston from the engagement position to a standby position between the release position and the engagement position and urges the piston toward the release position. The second return spring contacts the piston from he engagement position to the release position and urges the piston toward the release position. Center axes of the first and second return springs are arranged to coincide with a center axis of the rotating shaft.
