Abstract
An engaging device is provided which includes support members having respective splines that face with each other in a radial direction, a plurality of first friction plates that mesh with the spline of one of the support members, a plurality of second friction plates that mesh with the spline of the other support member, the first and second friction plates alternately overlapping with each other in an annular overlap portion of the engaging device, and a hydraulic piston that is held by the one support member to be movable in a direction of an axis of relative rotation of the support members. The hydraulic piston has a plurality of pressing parts that are spaced from each other in a circumferential direction, for pressing the first and second friction plates in an axial direction thereby to given an engaging force to the friction plates. The engaging device further includes a pressure receiving plate disposed between the friction plates and the hydraulic piston, comprising an annular plate portion that meshes with the spline of the support member holding the hydraulic piston, and a cylindrical pressure receiving portion protruding from the annular plate portion toward the hydraulic piston and having an end face that is able to abut on the pressing parts of the hydraulic piston.
