る。 Conventional ball stud receiving casings are cold-forged and then machined, and to ensure wear resistance, the steel is hardened by high-frequency processing or carburizing, or other hardened parts or wear-resistant sheet parts are used. However, the present invention uses a reinforced metal tube with a special structure made by expanding or contracting the pipe, and uses a ball stud receiving housing formed by molding a material such as synthetic resin on the inside and outside of the tube. The aim is to reduce weight, size and cost.

することができる。 In order to assemble the thus assembled ball stud receiving housing 5 to the cylindrical part 3 of the support member 2, the casing 5 is press-fitted onto the cylindrical part 3 from above, and then the caulking part 4 is processed by a caulking process. Accordingly, the caulking part 4 can be pushed out through the outer synthetic resin member 7 of the ball stud receiving housing 5, and can be caulked and fitted in accordance with the pull-out stopper part 11.

ある。 According to the above configuration, the mounting hole cylindrical portion 3 and the reinforcing metal tube 6
By forming a synthetic resin member 7 with a substantially uniform thickness according to the shape of the reinforced metal tube 6, the synthetic resin member 8 is formed on the inside of the reinforced metal tube 6. The resin members 7 and 8 form a double layer, which has the effect of absorbing shocks and vibrations received by the support member, and the transverse links of the support member 2 are press-fitted into the ball stud receiver housing 5 by press-fitting and caulking to accommodate the ball stud receiver. This compensates for the lack of rigidity due to the use of plastic for the housing 5, allows the ball stud receiving housing 5 to be elastically and reliably fixed together, and can be easily assembled.

上が計れる。 Furthermore, a synthetic resin member 7 is attached to the dust cover fitting part 16.
The presence of the dust cover 15 makes it easy to press-fit the dust cover 15, and the dust cover press-fit ring 1
By biting 6', the strength to pull out the dust cover can be improved.
