    摘要: A friction device for an automatic transmission according to the invention includes a retainer, a wave coil spring, a center support, a piston, and a plurality of plates. The retainer is disposed on the inner circumference of a transmission case. The wave coil spring is disposed on a seating portion of the retainer. The center support is disposed in the transmission case. The piston is disposed in a pressure chamber of the center support and provided with a return force by contacting with the wave coil spring. The plates are spline-connected with the inner circumference of the transmission case and pressed by the piston. Further, the retainer has a protruding portion to align the center axis of the wave coil spring with the center axis of the transmission case.
