Claims

[Claim for Utility Model Registration] A fluid-filled bushing is provided in the vehicle body support part of the suspension member that contributes to the rigidity of the front wheel caster, and the fluid-filled bushing has a rubber material between the inner cylinder and the outer cylinder. In a front suspension device in which a plurality of fluid-filled chambers are defined inside the rubber material, the fluid-filled chambers of the fluid-filled bushing are communicated through a communication passage, and the communication passage A front suspension device characterized in that an opening/closing valve is provided in the middle of the suspension member, which maintains an open state when the stroke of the suspension member is less than a predetermined stroke, and closes when the stroke exceeds the predetermined stroke.
