To provide a railroad vehicle yaw damper device which can easily reduce lateral vibrations and improve ride comfort in a railroad vehicle when a railroad vehicle travels at a high speed on a straight section of a track.SOLUTION: A yaw damper device 100 in this invention comprises a pair of yaw dampers 1a, 1b in both sides of a truck 3 respectively and each pair of yaw dampers are installed on the truck to be arranged in a traveling direction. The pair of yaw dampers are attached to the truck in a state that expanding and contracting directions Ea, Eb of the damper in the left side of the truck are inclined leftwards from the traveling direction of the truck and corresponding directions Ea, Eb of the damper in the right side of the truck are inclined rightwards from the traveling direction of the truck (the angle α between the expanding and contracting direction and the traveling direction of the truck is preferably not less than one degree and not more than three degrees).SELECTED DRAWING: Figure 6
