Abstract

A housing component for a hydrodynamic clutch device, especially a hydrodynamic torque converter, possesses a friction surface region for a converter lock-up clutch of the clutch device on a first side which is positionable for facing the interior of the clutch device. This housing component is formed by, at least in the region of the friction surface region, the reshaping of a metal component. On a second side of the housing component lying opposite to the first side a surface structuring is formed in a region corresponding to the friction surface region by reshaping of the metal component to form the friction surface region.
