To provide an appropriate compliance steer characteristics for lateral force and longitudinal force acting on a rear wheel of a three-wheeled vehicle having two front wheels and one rear wheel.
In a vehicle suspension device 10, respective rear ends of an upper side trailing link 42 and a lower side trailing link 48 are connected to an upper side connection part 66 and a lower side connection part 68 of a rear axle bracket 40 through an upper side rubber bush 46 and a lower side rubber bush 50. The connection parts are disposed on a virtual king pin shaft more on a vehicle front side than a wheel center of a rear wheel 38. Also, the device includes a control link 55 whose front end is freely rotatably connected to a vehicle body 20 and rear end part is freely rotatably connected to the rear axle bracket 40 more on a vehicle rear side than the wheel center, and when lateral force or longitudinal force acts on the rear wheel 38, the rear wheel 38 is steered by a fine angle around the king pin shaft by appropriate bending of the rubber bushes 46 and 50 and rotating direction regulation by the control link 55.
