Abstract
A spring retainer for a clutch piston has a cylindrical through portion engaged with the shank of a clutch drum and abutting a snap ring at one end. A dish bearing portion is connected to a second end of the through portion and extends in a frusto-conical manner in an axial direction of the shank. In use, the dish bearing portion abuts a dish spring, and a clearance is maintained between the dish bearing portion and the snap ring.
