To provide a brake shoe for railway vehicle in which attachment such as water, snow, grease and the like can be removed easily, in which such attachment hardly enters between the brake shoe and a vehicle tread, and which has high durability.SOLUTION: In a brake shoe 1 for braking wheels by coming into slide contact with a wheel tread of a railway vehicle, a groove part 5 is formed in the width direction at a central part of the brake shoe 1. The groove part 5 includes opposing surfaces 6a, 6b along the width direction, and inclined surfaces 7a, 7b opening to a non-flange side of the wheel. Both end parts of the brake shoe 1 are formed by inclined surfaces 3a, 3b. In the inclined surfaces 3a, 3b, the flange side of the wheel is long and the non-flange side is short, and the back surface side is high and the wheel slide contact surface side is low inclination. Corner parts 4a, 4b on the flange side of the inclined surfaces 3a, 3b are formed in a circular arc-shape.SELECTED DRAWING: Figure 1
【課題】水、雪、グリス等の付着物は排除しやすく、制輪子と車両踏面との間に入りにくく、耐久性も高い鉄道車両用制輪子を提供する。【解決手段】鉄道車両の車輪踏面に摺接して車輪にブレーキをかけるための制輪子1であって、制輪子1の中央部の幅方向には溝部5が形成され、溝部5は幅方向に沿った対立面6a,6bと、車輪の非フランジ側に開く傾斜面7a,7bを備え、制輪子1の両端部は傾斜面3a,3bで形成され、傾斜面3a,3bは車輪のフランジ側が長く非フランジ側が短かく、かつ背面側が高く車輪摺接面側が低い傾斜であり、傾斜面3a,3bの前記フランジ側の角部4a,4bは円弧状に形成されている。【選択図】図1
