Abstract
A front cover affixed to the pump impeller of a torque converter, provided with a flat annular flat annular surface to be engaged with the clutch disk of a direct-coupling clutch formed within the torque converter. The flat annular surface is formed in a flat and annular surface having a hard and compact metallographic structure by rolling a rolling tool made of a extremely hard material on the flat annular surface under a pressure and by thus causing plastic deformation of the flat annular surface. An intermediate part of an arcuate section of a small radius is formed between the periphery of said flat annular surface and a connecting part adjacent to the flat annular surface.
