PROBLEM TO BE SOLVED: To provide a vibration control device of a railway vehicle, which can extend a life of a component of a pump, a motor and the like.SOLUTION: One aspect of the present invention has a damper 5 for vibration control, which is provided between a vehicle body 2 and a truck 3 so as to suppress vibrations generated in the vehicle body 2. The damper 5 for vibration control comprises a semi-active damper that comprises a cylinder 10, a pump 31 that supplies a hydraulic fluid to the cylinder 10, and a motor 32 that drives the pump 31. A vibration control device 8 of the railway vehicle 1 includes a vibration control controller 6 that controls a revolving speed of the motor 32 to make it lower than a necessary maximum revolving speed, under specific conditions during the traveling of the railway vehicle 1.SELECTED DRAWING: Figure 2
