PROBLEM TO BE SOLVED: To accomplish both of suppression of an excessive posture change and improvement of comfortableness by setting damping performance, which can satisfies a special relationship, of a throttle member on the basis of a damping force in compliance with a dimension of a relative stroke bead difference between both wheel ends in a vehicle suspension provided with the throttle member. SOLUTION: A suspension 1 is provided with hydraulic cylinders 2, 3, which are installed on left and right wheels or front and rear wheels, and a pressure controller 4 connected to the respective hydraulic cylinders 2, 3 via oil pressure paths 6, 7 individually. The both oil pressure paths 6, 7 are connected to each other by means of a throttle member 5. In this case, damping performance of the throttle member 5 is set so that a damping forceαwhich is generated by means of the throttle member 5 when a relative stroke speed difference between wheel ends of the both wheels is 0.2m/s, a damping forceβwhich is generated by means of the throttle member 5 when the stroke speed difference is 2.0m/s, a total weight W of the both wheels in the contact points, and a distance L between contact center points of the both wheels satisfyβ-α<=0.3.W/L.
