摘要： The present invention relates to a frictional engagement apparatus comprising a first frictional engagement unit (42), a second frictional engagement unit (44) and being disposed axially spaced from the first frictional engaging unit, and one case (40) for supporting the first and the second frictional engagement unit non-rotatably circumferentially but shiftably axially relative thereto. One retaining ring (51) is fitted to the case to be located between the first and second frictional engagement unit, the retaining ring being abutted to the nearest first friction plate and/or the second friction plate to stop an approaching shift of the first frictional engagement unit and/or the second frictional engagement unit. At a portion of the retaining ring remote from the case a recess (51a) is formed for allowing an elastic deformation in a direction decreasing thickness thereof, when the first and second frictional engagement units approach to each other.

摘要： A wave spring holding structure includes a wave spring that includes crest portions and recessed portions that are alternately formed in a circumferential direction thereof, and a first gap; a circular member provided to be rotatable around an axis; and an arc-shaped snap ring that includes a second gap, and that restricts movement of the circular member in a direction of the axis. The wave spring and the snap ring share the axis with the circular member. The wave spring and the snap ring are rotatable with respect to each other. The wave spring is disposed and held between the circular member and the snap ring so that the crest portions protrude toward the circular member, and the recessed portions protrude toward the snap ring. The first gap is formed in one of the crest portions.

摘要： A second clutch piston formed of a plurality of members including a cylindrical cylinder member, a disc-shaped bottom plate member that fits in one end portion of that cylinder member, and a snap ring, has a plurality of long positioning protrusions provided on an inner peripheral surface of the cylinder member. By abutting the disc-shaped bottom plate member against end surfaces of these positioning protrusions, the bottom plate member can be fit into the one end portion of the cylinder member without having to provide notches therein, which enables durability against a pulling force generated in the cylinder member when the friction apply device is applied to be maintained.
