PROBLEM TO BE SOLVED: To achieve both improvement of a steering stability and improvement of vibration control and noise suppression performances by suppressing rolls at a fine lateral force input time without unnecessarily increasing rigidity of a mount member.SOLUTION: A connection position between a lower arm 10 and a front cross member 30 via a bush 12 is disposed with an inclination so as to become higher than a connection position between the lower arm 10 and an axle housing 3. Also, elasticity of the bush 12 in the vertical directions and the horizontal directions is optimized such that an elastic center of the right and left bushes 12 is set adjacent to an axis of inertia of a vehicle. In this way, it is possible to achieve both improvement of a steering stability and improvement of vibration control and noise suppression performances by suppressing rolls at a fine input time without unnecessarily increasing rigidity of the bush 12.SELECTED DRAWING: Figure 4 |
