Patent ID: 7219909

Claim:
A front suspension device for an automotive vehicle, in which wheel support members of right and left front wheels are coupled with each other via a steering unit, an outer end of each of two lower arms is pivotally attached to the wheel support members respectively, and an inner end of each of two lower arms is pivotally attached to a vehicle body via a resilient member respectively, the front suspension device comprising: a damping device equipped with a coil spring and attached to at least one of said two lower arms at a lower end thereof and to the vehicle body at an upper end thereof, respectively; and a suppression device for suppressing a toe-change of said front wheels caused by a rotational torque which is applied to said at least one of the two lower arms, to which said damping device is attached, according to extension and contraction of said coil spring of the damping device, wherein said suppression device includes a vehicle body member which constitutes part of the vehicle body to which said damping device is attached at the upper end thereof and is equipped with an elongated hole formed so as to extend in a circumferential direction of the damping device, and an attaching member for attaching said damping device to the vehicle body with an attaching bolt which is adaptive to get through said elongated hole of the vehicle body member, and said damping device is attached to the vehicle body by said attaching member such that said attaching bolt is fastened in a state where there is provided no or a small amount of rotational torque applied to said at least one of the two lower arms, by applying a load corresponding to a vehicle weight to said coil spring so as to allow the attaching bolt unfastened to move in and along said elongated hole.
