ABSTRACT:
The structure comprises a molded plastics housing either having a metallic sleeve molded therein which forms a cylinder for a piston or defining the cylinder itself. An annular retainer for the piston is provided which abuts a location surface of the sleeve or an anchoring element molded in the housing. The location surface is provided by deforming the sleeve or anchoring element so that the location surface engages the annular retainer at a position radially inboard of its outer periphery.
