PROBLEM TO BE SOLVED: To provide a suspension device for front wheels capable of reducing the vibration transmitted to a vehicle body even when the time difference occurs between the input received by the front wheels and the input received by rear wheels during the travel. SOLUTION: The suspension device for front wheels has a variable rigidity connection member 14 for connecting a vehicle body side member to an arm member, and suspends the front wheels by the vehicle body via the arm member for connecting a wheel supporting member for rotatably supporting the front wheels and the vehicle body. A liquid chamber 40 is formed inside an elastic body 32 provided in the variable rigidity connection member 14. The supporting rigidity of the front wheels by the variable rigidity connection member 14 is controlled so that the natural vibration of the front wheels in the vehicle longitudinal direction and the natural vibration of the rear wheels in the vehicle longitudinal direction have the phases opposite to each other by applying the magnetic field to the magnetic fluid 62 enclosed in the liquid chamber 40 according to the natural vibration of the front wheels in the vehicle longitudinal direction and the vehicle speed.
