Abstract: A clutch hub provided with a side wall at an end of a cylindrical portion. The cylindrical portion is formed to have convexed and concaved portions to serve as a spline and an oil passage is formed on a tooth of the spline. An oil dam is formed by plastic deformation on the inner peripheral surface of the tooth of the spline with the oil passage formed thereon at a position separated from an open end by a predetermined distance, concaved grooves are formed on the outer peripheral surface of the spline with the oil dam formed thereon.

Abstract: A hydraulic clutch has an operating hydraulic chamber, an operational member pushed in an axial direction thereof by a hydraulic fluid supplied from the operating hydraulic chamber so as to transmit torque by engaging frictional engaging elements, a non-operational member that defines the operating hydraulic chamber with the operational member, the non-operational member having a seal member setting portion thereon and a seal member provided in the seal member setting portion of the non-operational member. A bottom surface of the seal member setting portion is inclined so as to gradually shallow towards a direction that the operational member is pushed.

Abstract: A multiplate clutch is provided with a clutch case and a sleeve fitted in an inner circumferential wall of the clutch case with their piston oilways registered with each other. The sleeve is provided in an outer circumference thereof with at least one notch. The inner circumferential wall of the clutch case has been crimped at a portion thereof into each notch such that a crimped portion is formed to fixedly secure the sleeve on the inner circumferential wall of the clutch case. Preferably, the crimped portion can be formed such that a front surface of the crimped portion is shallower on a side of the sleeve and deeper on a side of the clutch case. The front surface may desirably have an inclination of from 5 to 15°. Desirably, the sleeve can be provided with two or more notches.

Abstract: A hydraulic pressure control valve for use in a hydraulic multiplate clutch assembly includes a valve plate having a ridge-shaped, elevated portion formed in a proximity of at least a part of the valve plate, where a deformation is to take place in a staking step to be performed upon assembly of the hydraulic pressure control valve. The ridge-shaped, elevated portion serves to prevent the deformation from spreading to a closing part of the valve plate for an associated oil leak hole.
