PROBLEM TO BE SOLVED: To provide a yaw damper device for a railway vehicle capable of improving riding comfortableness of the railway vehicle by easily reducing flexural vibration in a vertical direction of a vehicle body when the railway vehicle travels at high speed in a straight section of a track.SOLUTION: A yaw damper device 100 is used for a railway vehicle including a vehicle body 2 and a truck 3 connected to the vehicle body 2. The yaw damper device includes a pair of yaw dampers 1a and 1b on right and left sides of the truck that are arranged in parallel in a longitudinal direction of the truck 3. In both end parts E1 and E2 of the pair of yaw dampers in their telescopic direction, both end parts E1 positioned at end part sides of the vehicle body are mounted on a truck and both end parts E2 positioned at the center side of the vehicle body are mounted on the vehicle body or both end parts E1 positioned at the end part sides of the vehicle body are mounted on the vehicle body and both end parts E2 positioned at the center side of the vehicle body are mounted on the truck.SELECTED DRAWING: Figure 1
【課題】鉄道車両が軌道の直線区間を高速走行する際に、車体の上下方向の曲げ振動を容易に低減して鉄道車両の乗り心地を向上させることが可能な鉄道車両用ヨーダンパ装置を提供する。【解決手段】本発明に係るヨーダンパ装置100は、車体2と車体2に連結された台車3とを具備する鉄道車両に用いられる。本発明に係るヨーダンパ装置は、台車3の前後方向に並設された1対のヨーダンパ1a、1bを台車の左右それぞれに備え、1対のヨーダンパは、それらの伸縮方向の両端部E1、E2のうち、車体の端部側に位置する双方の端部E1が台車に取り付けられ、車体の中央側に位置する双方の端部E2が車体に取り付けられているか、或いは、車体の端部側に位置する双方の端部E1が車体に取り付けられ、車体の中央側に位置する双方の端部E2が台車に取り付けられている、ことを特徴とする。【選択図】 図1
