To control a camber angle to an adequate value by the use of a lateral force acting on a wheel, without causing a displacement of a tire ground contact point. A suspension device includes a link mechanism replaceable by a first virtual link 11 which, when a lateral force acts at a tire ground contact point, inclines a wheel in a camber angle direction with respect to a vehicle body so as to increase the lateral force, and a second virtual link 12 which is connected virtually and rotatably between the first virtual link 11 and the vehicle body 1 and which is arranged to allow the wheel 2 to move in the up-and-down direction with respect to the vehicle body 1 in accordance with a load variation of the wheel in the up-and-down direction. A rotation center A in the camber angle direction and a rotation center B in the up-and-down direction, of the wheel with respect to the vehicle body are arranged so that a lateral movement amount of the tire ground contact point due to a change in the position of the first virtual link 11 is canceled by a lateral movement amount of the tire ground contact point due to a change in the position of the second virtual link 12.
