To provide a railroad vehicle which efficiently transmits exciting force from a truck to an underframe via a yaw damper and a yaw damper support part, has sufficient strength and can reduce manufacturing manhours.SOLUTION: A railroad vehicle includes: an underframe extending in a longitudinal direction of the railroad vehicle; a side structural body extending from an end part of the underframe in a height direction of the railroad vehicle; a body bolster corresponding to a position of a truck in the longitudinal direction of the railroad vehicle and located on a lower side of the underframe; a yaw damper extending from the truck in the longitudinal direction of the railroad vehicle; and a yaw damper support member connected to one end of the yaw damper with the other end connected to body bolster. Then, the body bolster is configured to be integrally pushed out in the longitudinal direction of the railroad vehicle in a uniform cross section on an outer side from the side structural body in a width direction of the railroad vehicle, and has a support structure part connected to the yaw damper support member.SELECTED DRAWING: Figure 4
【課題】台車からヨーダンパと、ヨーダンパ支持部を経由して台枠に伝達される加振力を鉄道車両構体に効率的に伝達するとともに、十分な強度を備え、且つ製作工数を低減できる鉄道車両を提供する。【解決手段】鉄道車両の長手方向に延びる台枠と、台枠の端部から鉄道車両の高さ方向に伸びる側構体と、鉄道車両の長手方向において台車の位置に対応し、台枠の下側に位置する枕梁と、台車から鉄道車両の長手方向に延びるヨーダンパと、ヨーダンパの一端に接続され、他端を枕梁に接続されるヨーダンパ支持部材と、を備える。そして、枕梁は、鉄道車両の幅方向に側構体よりも外側に、鉄道車両の長手方向に一様断面で一体に押し出されて構成され、ヨーダンパ支持部材と接続される支持構造部を有する。【選択図】 図4
