Abstract

PROBLEM TO BE SOLVED: To prevent abrasion of a power transmitting member to be generated at a fitting portion between a diametral projection of the power transmitting member and an axial projection of a rotary drum without changing a layout of an automatic transmission. SOLUTION: A diametral projection to be fitted to an axial projection 4p of a clutch drum 4 is formed on an outer periphery of a shell cone 1 which is rotated unitedly with a sun gear 5. The projection is bent and superposed to form a projection 1p. Axial thickness D of the projection 1p is more than thickness (d) of other part. It is thus possible to prevent abrasion of the shell cone 1 to be generated at a fitting portion between the projection 1p and the projection 4p without changing a layout of an automatic transmission.
