In a second state, the first friction engagement mechanism (10) is in a released state to make the ring gear (36) run idle, and the pinion gear (34) rotates instead of revolving even when the input shaft (52) rotates, whereby the torque from the input shaft (52) is not transmitted to the output shaft (62).

Due to the second state as a neutral state being interposed between the first state and the third state, the number of components can be relatively reduced and a glitch can be easily prevented.

[Problem] To provide a frictional engagement device that is compact, has a large transmission torque capacity, and is not prone to producing drag torque. [Solution] A frictional engagement device 10 in which, when a piston 22 is activated while differential rotation and torsional torque are occurring in a clutch drum 12 and an output shaft 62, a plate 36 and a friction plate 38 frictionally engage, rotation of a pilot clutch hub 32 causes a rolling body 42 to roll or slide over inclined surfaces 44, 46 of the pilot clutch hub 32 and the push cone 52 and causes the push cone 52 to move in an axial direction, and, due to frictional engagement by the cone clutch, torque of the clutch drum 12 is transmitted to the output shaft via the cone clutch 50. The push cone 52 and an outer cone 54 are biased by first and second separator springs 66, 56 in a direction away from frictional engagement by the cone clutch 50. Thus, the present invention is compact, has a large transmission torque capacity, and is not prone to producing drag torque.
