A fastening material a for fastening to the vehicle body is joined by welding or the like to the suspension link S that suspends. In order to relieve stress at the joint, the fastening material a is required to have a thin plate thickness at the joint and conform to the shape of the suspension link S. That is, in the case of manufacturing the fastening material a by cold working, as shown in FIG. 5, a collar b is formed on the way of the steel rod, and a threaded portion c is formed at one end of the steel rod. The end is formed in conformity with the shape of the suspension link S. However, in the manufacturing by cold working, it is difficult to work according to the shape of the suspension link S because of working limits (drawing, buckling, compression, etc.). So conventionally,
As shown in FIG. 5, the joint portion of the fastening material a is flatly pressed to form the flat pressure processed portion d, and then the flat pressure processed portion d is trimmed and processed according to the shape of the suspension link S. (Trimming part e). Further, as shown in FIG. 6, a method of joining another plate material g to the flat-pressed portion f by welding is also common.

別の板材を溶接する方法もコスト面から問題である。The conventional flat pressing method is uneconomical because it requires a large amount of material because it is necessary to expand the joint to a size that fits the suspension link. Further, since the flat pressing area is wide and a large pressing force is required, a large pressurizer must be used. further,
The method of welding another plate material is also problematic in terms of cost.

To do. The steel rod 1 on one side (shorter side) of the collar 11 is provided with a threaded portion 12 for fastening the suspension link and the vehicle body. Then, the steel rod 1 on the other side of the collar 11 is flattened to form the flat pressure working portion 13. It is not necessary to widen the flattening portion 13 as in the conventional case, and it is sufficient to form it flat to some extent by cold working. Therefore, it is not necessary to use a large-sized flat pressure machine as in the prior art.
