ABSTRACT:
An object of the present invention is to provide a suspension of a motor vehicle which can prevent rusting, reduce the manufacturing cost, and easily make the stress occurring inside uniform. To achieve the above object, the suspension is so constructed that an arm body 4 is formed as a whole in an approximate inverse U shape in cross section, and an arm pin portion 6 is fixed by welding to the arm body so that a closed cross section is formed by the arm body 4 and the arm pin portion 6. Further, according to the present invention, the thickness of the arm pin portion 6 is gradually decreased from its center 6b to its base 6c, the center portion 5b of the arm reinforcing member 5 is slightly offset downward, one end 5a of the arm reinforcing member 5 overlaps with the base 6c of the arm pin portion 6, and the arm reinforcing member 5 and the arm pin portion 6 are fixed by welding to the lower part of the arm body 4, by which the change in stiffness of the suspension arm 2 from the arm pin portion 6 to the arm reinforcing member 5 is made smooth.
