To improve durability of a bush by arranging the elastic material bush between an inner cylinder supported by a car body and an outer cylinder fixed thereto a suspension are, and arranging the inner cylinder so as to be freely rotatable to the support shaft.

In a rear suspension, an elastic body bush 3 is fixed to the front end of a trailing arm 1, and theses are joined to a car body via a bracket 5. The bracket 5 is formed in an almost U shape, an outside plate 13 is installed on the car body lateral side of an upper plate, an inside plate 14 is installed on the car body central side of the upper plate, respectively, and the upper plate is fixed to a cross member. In this case, an inner cylinder 24 of the elastic body bush 3 is formed in the shape of opening a through hole 25 by obliquely cutting a steel solid material of a cross-sectional cylindrical shape, and the inclining direction is set so that the toe correcting action can be obtained, that is, so that an outer cylinder 21 is displaced forward via a bush 17 when the inner cylinder 24 is pushed to the car body lateral side.
