A suspension device includes a wheel supporting member configured to rotatably support a wheel. Two links respectively link the wheel supporting member and a vehicle-body side member and are disposed substantially in parallel in a vehicle width direction. At least one projecting portion extends from at least one of the two links towards the other link, and an elastic linking portion links the projecting portion of one of the links to at least one of the other link and the projecting portion of the other link. A toe angle adjusting device is configured to input a force in a direction oriented backward in the vehicle forward-backward direction to the wheel supporting member to adjust a toe-in angle of the wheel.
