Abstract
The housing of the slave cylinder in an apparatus for actuating a friction clutch between the engine and the input shaft of the change-speed transmission in the power train of a motor vehicle has a one-piece metallic or plastic member which is non-rotatably affixed to the transmission case. The annular piston of the slave cylinder carries a clutch release bearing and is surrounded by a wall of the housing; this piston slidably surrounds a deep-drawn metallic guide sleeve which is centered in the transmission case and has a flange secured to a collar of the housing by two or more lugs having mutually inclined portions partially bent around and partially recessed into the collar.
