素。[Scope of Claim for Utility Model Registration] 1. A friction engagement element piston that applies a coupling force to a friction plate, and a return spring that applies a biasing force in the direction of releasing the engagement to the friction engagement element piston,
The return spring is a single coil spring having a spring axis coaxial with the piston center axis, and one end is in contact with the friction engagement element piston,
A frictional coupling element for an automatic transmission, the other end of which is locked to a snap spring provided on a support member coaxial with the piston center axis and received by a spring retainer centered on the support member, wherein the spring The retainer has a support plate portion that receives a spring end, a locking piece that is locked to a snap spring, and a centering piece that guides a return spring, and the support plate portion has an outer diameter that approximately matches the outer diameter of the spring. The locking pieces are formed by extending radially inward from the inner periphery of the support plate portion, and the centering pieces extend axially from between adjacent locking pieces. A friction coupling element for an automatic transmission, characterized in that it is formed by extending a plurality of pieces, and the inner diameter of the centering piece is set smaller than the outer diameter of the snap spring. 2. The friction engagement element for an automatic transmission according to claim 1, wherein the centering piece has an arc shape when viewed from the axial direction, and has a curvature smaller than a curvature of the return spring.
