Abstract
The torsion beam for a suspension is formed of a hollow shaft having a cross section substantially of the shape of an inverted letter U. It, therefore, can be manufactured simply and is enabled to enjoy light weight and improved torsional rigidity. This torsional rigidity can be adjusted and the amount of offset of the joined parts of opposite wheel supporting members from the other component parts can be freely adjusted. The end plates are constructed of a plurality of mutually joined end plates and the torsion beam is joined by welding to the surface for mounting the beam after the end plates have been machined. Thus, the torsion beam type suspension is manufactured with a relatively simple equipment, with the result that cost of equipment and the cost of production are lowered. The torsion beam can be manufactured with increased simplicity by subjecting a flat plate to the steps for swelling, folding and joining opposed of the flat plate or superposing a first and a second plate severally formed in a structure having a cross section substantially of the shape of an inverted letter U.
