To provide a cowcatcher for a railway vehicle capable of reducing a possibility of derailment of the railway vehicle by reducing moment force for turning a vehicle body caused by its collision reaction force when the railway vehicle collides with an obstacle with a large mass such as a standard-sized vehicle.SOLUTION: A cowcatcher 10 for a railway vehicle is mounted on a head part 1S of a railway vehicle 1 and is formed to remove an obstacle S on a rail track. The cowcatcher includes a life guard plate 11 with a horizontal cross sectional shape including a curved surface body or a polyhedron with a circular arc shape around a shaft SJ1 that passes the vicinity of a center SJ of gravity of a vehicle body of the railway vehicle and is perpendicular to the ground.SELECTED DRAWING: Figure 3

    【課題】普通乗用車等のように質量の大きな障害物と衝突した場合において、その衝突反力によって生じる車体を回転させるモーメント力を低減させて、鉄道車両の脱線する可能性を軽減できる鉄道車両の排障器を提供する。【解決手段】鉄道車両1の先頭部1Sに装着され、線路上の障害物Sを排除可能に形成された鉄道車両の排障器10である。排障器は、水平断面形状が鉄道車両の車体重心SJ近傍を通り地面に垂直な軸SJ1を中心とする円弧形状を構成する曲面体又は多面体からなる排障板11を備えている。【選択図】 図3
