Abstract
A spring retainer for a damper for use in a torque converter is provided. The spring retainer includes a ring including a radially extending base and a spring retaining portion radially outside of the base. The spring retaining portion includes rounded sections spaced circumferentially from each other and shoulders circumferentially between the rounded sections. Each rounded section is configured for receiving an arc spring. The spring retainer also includes rivets fixed to the shoulders. The rivets protrude axially from the shoulders into an interior of the spring receiving portion and are arranged for contacting ends of the springs. A method of forming a spring retainer is also provided.
