Patent ID: 7588261

Claim:
A suspension device comprising: a trailing arm that extends in a front-to-rear direction of a vehicle and that is connected to a body of the vehicle by its front end and an axle that rotatably supports a wheel of the vehicle, the trailing arm elastically supporting the axle via an upper connecting point and first and second lower connecting points, the first and second lower connecting points being positioned lower than the upper connecting point and mutually spaced apart in the front-to-rear direction of the vehicle, the upper connecting point being positioned inside of the first and second lower connecting points in a vehicle width direction of the vehicle; and an cylindrical elastic member placed at each of the upper connecting point and the first and second lower connecting points, each elastic member having a central axis and a principal elastic axis that extends perpendicular to the central axis and passes through a geometric center of the elastic member, the central axes of the elastic members placed at the first and second lower connecting points intersecting at an inside location inside of the first and second lower connecting points in the vehicle width direction of the vehicle, the principal elastic axes of the elastic members placed at the first and second lower connecting points intersecting at an outside location outside of the first and second lower connecting points in the vehicle width direction of the vehicle, a kingpin axis connecting the upper connecting point to the outside location intersecting with the ground at a kingpin grounding point which lies outside and to a rear of a grounding point of the wheel.
