PROBLEM TO BE SOLVED: To stably damp vibration when a vehicle travels by controlling a flow rate by detecting a liquid oil temperature in a suspension cylinder. SOLUTION: Oil chamber pressures in the right and left front suspension cylinders 8L, 8R and the left and right rear suspension cylinders llL, llR are detected by pressure sensors l8L, l8R, 19L and 19R. Temperatures of liquid oil supplied to and discharged from oil chambers A of the front suspension cylinders 8L, 8R and the rear suspension cylinders 11L, 11R, etc. are detected by temperature sensors 20l, 20R, 21L and 21R. A control device 22 is devised so as to generate a proper damping force in response to travelling conditions by independently and variably controlling openings of flow rate control valves 14L, 14R, 17L and 17R according to respective detection signals read from these pressure sensors 18L, 18R, 19L and l9R and the temperature sensors 20L, 20R, 21L and 21R.
