Abstract:
Protruding portions have an agitation face on the side surface thereof to agitate or dam hydraulic oil. An oil chamber defining portion has a supply hole that is allowed to supply the hydraulic oil from outside a hydraulic oil chamber by communicating with the hydraulic oil chamber from the rotational center side. When the protruding portions abut against the oil chamber defining portion so that the capacity of the hydraulic oil chamber is minimized, the supply hole faces, in a radial direction, a flow passage that is surrounded by circumferentially adjacent ones of the protruding portions, an oil chamber defining portion, and a piston.

Claim (Index 23):
A power transmission device comprising:\n an input member to be driven by a drive source; an output member; and a speed change mechanism disposed in a power transmission path between the input member and the output member and operable by oil pressure supplied to and discharged from the speed change mechanism to change a speed ratio between the input member and the output member, wherein the speed change mechanism has a plurality of friction engagement elements including the clutch device of  claim 10  and is operable to establish a plurality of shift speeds in accordance with simultaneously engaged combinations of the plurality of friction engagement elements, the input member has a communication hole for supplying hydraulic oil to the supply hole in the oil chamber defining portion, the oil chamber defining portion and the piston of the clutch device are formed to one of rotating elements that rotates when a predetermined forward shift speed is established, and the one of the rotating elements rotates faster than any other of the rotating elements.
