PURPOSE:To aim at enhancing the comfortability in riding by making the direction of the forward and downward axis of a pair of right and left upper arms cross with the direction of the forward and upward axis of a pair of right and left upper arms, and by crossing extensions of the axes of the lower arms in a V-like shape. CONSTITUTION:A pair of left and right upper arms 11, 12 in a rear suspension 10 are arranged at a suitable interval in the transverse direction of a chassis, and axle tubes 31, 32 are secured to a bracket on the chassis with the axis of each arm being inclined forwardly downward in the longitudinal direction of the chassis. Further, a pair of left and right lower arms 13 are arranged in a V-like shape so that their axes viewed in a plan view crosses over to each other at a cross-point 20 which is rear of the center axis of a rear axle by a predetermined distance LC 2. Further, the forwardly upward inclined axes of the lower arms 13 crosses over to the forwardly downward inclined axes of the upper arms 11, 12. That is, the cross-point C is positioned front of, for example, the axis of the rear axle by a predetermined distance Ld, and at a predetermined height Hc from a road surface 40. |
