摘要： A vibration damping device for railway vehicle includes an actuator and a damper circuit that causes the actuator to function as a damper. The actuator includes a cylinder coupled to a truck of a railway vehicle, a piston, a rod coupled to the piston and a body, a rod-side chamber and a piston-side chamber inside the cylinder, a first on-off valve for a first passage that communicates between a rod-side chamber and a piston-side chamber, a second on-off valve for a second passage that communicates between the piston-side chamber and a tank, and a pump that supplies a hydraulic fluid into the rod-side chamber. The hydraulic fluid has such kinematic viscosity-temperature characteristics that a kinematic viscosity of the hydraulic fluid ranges from 7 mm2/s to 50 mm2/s in a temperature range of from 20° C. to 60° C.
