<p><P>PROBLEM TO BE SOLVED: To provide a suspension structure for a vehicle that improves a torsional property of a torsion beam to improve steering stability while suppressing degradation in productivity due to an increase in weight and manufacturing cost, and preventing a crack and the like. <P>SOLUTION: The suspension structure is provided with a pair of right and left trailing arms 1 and a torsion beam 2 having a U-shaped or V-shaped cross-section. The torsion beam includes beam end faces 10 formed at its both ends in a longitudinal direction. On the outer circumferential face of the trailing arm, a convex face part 12 or a concave face part having a contact face 11 that can oppose to the beam end face is formed along the beam end face in the longitudinal direction. Each of both the end parts in the longitudinal direction of the torsion beam face are welded and fixed to the outer circumferential face of the trailing arm with the beam end face and the contact face in contact with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
