Abstract
Opposite ends of a torsion beam are connected to left and right trailing arms, and a spindle which supports a wheel is secured to a spindle support plate which is welded to each of the left and right trailing arms. Bent flanges which are formed in the outer periphery of a body of the spindle support plate, are fitted to the outer periphery of the end of trailing arm and secured by welding. With this arrangement, thermal warp of the body of the spindle support plate which supports spindle can be prevented, and not only can the mounting precision of the spindle be improved, but also the thickness of the spindle support plate can be reduced to reduce the weight.
