20130069293 | SUSPENSION DEVICE - A suspension device is equipped with a damper including a piston portion, a suspension spring, an upper seat, and a spring. The spring is arranged between the piston portion and the upper seat and is an elastic member for receiving a load from the damper.

Therefore, the spring constant in a direction perpendicular to an axis line of the damper is large, whereby stiffness in the direction perpendicular to the axis line is increased. As a result, ride quality is improved, and stable handling is obtained. | 03-21-2013 |
