A friction engagement device includes an elastic member between a piston and a friction plate in an axial direction. Elastic member includes: second engaged portion to be brought into engagement with engagement portion of tubular member so as to be movable in axial direction; and annular plate portion sandwiched between pressing surface of piston and friction plate from both sides in axial direction. Surface of annular plate portion facing first axial side is provided with projection and recess arranged alternately in circumferential direction. Assuming that a phase where radial groove provided in pressing surface and projection provided on annular plate portion are located at corresponding positions in circumferential direction is a particular phase, engagement portion of tubular member, first engaged portion of piston, and second engaged portion of elastic member are formed such that piston and elastic member are unable to come into engagement with tubular member at particular phase.
