Abstract
A pipe-type housing for a shock absorber has a bearing eye at one end for a fastening member. The housing is formed of a welded or continuous seamless steel pipe formed at one end by hot or cold extrusion to provide a flattened portion with two spaced generally parallel surfaces. Each of the surfaces has an opening aligned with the opening in the other. A flange extends around each opening and projects inwardly relative to the flattened section toward the other flange, however, the flanges are spaced apart. In the deformation of the pipe a transition wall is formed between the flattened part and the remaining part with the normal pipe cross-section. A base is inserted into the normal pipe cross-section abutting the transition wall. The base is sealed with the inner circumferential surface of the pipe by a seal ring fitted into a circumferentially extending groove in the base. With the base inserted into the pipe, a groove is rolled in the pipe and is pressed into the groove in the base into contact with the seal ring.
