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 24):
A clutch device comprising:\n a hydraulic servo including a piston, an oil chamber defining portion that rotates along with the piston, that supports the piston movably in an axial direction, and that forms together with the piston a variable capacity hydraulic oil chamber between the piston and the oil chamber defining portion, and a cancel plate portion that faces the oil chamber defining portion across the piston in the axial direction and that forms together with the piston a variable capacity cancel oil chamber between the piston and the cancel plate portion; a plurality of friction plates to be engaged by being pressed by the piston that moves in the axial direction in accordance with hydraulic oil supplied to the hydraulic oil chamber; and protruding portions that are formed at at least one of a facing portion of the oil chamber defining portion and a facing portion of the piston and that protrude in the axial direction toward the other of the facing portions, wherein the protruding portions have an agitation face on its side surface to agitate or dam the hydraulic oil, and the agitation face has a flat or concave surface extending in a direction crossing a circumferential direction.
