PURPOSE:To reduce the steering force of rear wheels by inclining the king-pin axis of the rear wheel so as to be farther away from the central surface of a tire as it goes upwards, and also specifying a king-pin offset, so that the wheel alignment of the rear wheels can be appropriately carried out. CONSTITUTION:In a rear wheel, for example, the right side rear wheel 11R of a rear wheel steering vehicle, a wheel support 40 provided with a knuckle arm 14R, which is connected to a tie rod 13R projected toward the rear of the vehicle body via a ball joint 50, is supported by both an upper arm 41 and a lower arm 42 via ball joints 43, 44 respectively. In this case, the king-pin axis KP connecting the centers of respective ball joints 43, 44 is arranged on the inner side of the vehicle body than the central surface S of the tire, and also is inclined so as to be farther away from the central surface S of the tire as it goes upwards. And the distance d between the intersection P of the king-pin axis KP and a road surface and the ground contacting central point G of the rear wheel 11R, or the king-pin offset is set to have a positive number. |
