To provide a suspension device compact in the vertical direction and adopted for a driving wheel of a simplified vehicle.

The suspension device 30 is constituted of an axis 33 to support a wheel, a leaf spring 31 to support the axis 33 free to vertically move and an axis correction part 35 to regulate inclination to stay it within a specified range in the case when the axis 33 is inclined. The axis correction part 35 is mainly constituted of a pair of independent correction arms 36 axially supported by a hinge pin 42 against a car body free to revolve and a rubber bush 43 externally fitted in the hinge pin 42 and regulates the inclination of the axis 33 by the rubber bush 43. As both of the correction arms 36 are independent from each other in this way, it is not necessary to arrange the correction arms 36 by vertically dislocating both of the parts 31, 36 even in the case of arranging the correction arms 36 on both left and right sides of the leaf spring 31. Consequently, it is possible to set a space required for arrangement of the axis correction part 35 thin.
