The position stopper resists the supporting member to secure the supporting member when the adjustment member is free.

Abstract: A railway vehicle vibration damping device having at least two vibration suppression force generating sources interposed between a bogie and a vehicle body of a railway vehicle extracts from a transverse direction velocity of the vehicle body a frequency component at or above a frequency of a centrifugal acceleration of the vehicle body, and calculates a high frequency vibration suppression force on the basis thereof. When the railway vehicle travels in a curve section, at least a part of the vibration suppression force generating sources is caused to output the high frequency vibration suppression force, and the remaining vibration suppression force generating sources are caused to function as passive dampers. As a result, passenger comfort in the railway vehicle during travel in a curve section is improved.
