To provide a brake shoe for railway capable of fixing a bracing part to a base plate while preventing distortion from being generated by heat or heavy load.SOLUTION: The present invention relates to a brake shoe 17 for railway comprising: a base plate 19 in which a lining 39 is molded on a surface opposite to a wheel 15; an attachment part 21 joined to an opposite side face 43 of a lining molded surface 41 in the base plate 19; and a bracing part 23 loosely fitted into a groove of a brake shoe head 11 and attached to the base plate 19 for suppressing oscillation in a width direction across a braking force application direction Y in the base plate 19. The bracing part 23 includes: an engage projection 25 which is inserted from the side of the lining molded surface 41 into a through-hole provided in the base plate 19 and of whose tip end protrudes from the opposite side face 43; and a stationary base part which is inserted/positioned while being abutted to the lining molded surface 41, and is caulked to an inner wall surface of the through-hole.SELECTED DRAWING: Figure 1
【課題】熱や大荷重によるゆがみを生じさせずに、振れ止め部を台板に固定できる鉄道用制輪子を提供する。【解決手段】車輪15との対向面にライニング39が成型された台板19と、台板19におけるライニング成型面41の反対側面43に接合された取付部21と、制輪子頭11の溝に遊嵌されて台板19における制動力付加方向Yと交差する幅方向の振れを抑制するために台板19に取り付けられた振れ止め部23と、を備えた鉄道用制輪子17であって、振れ止め部23が、台板19に設けられた貫通孔にライニング成型面41側から挿通されて反対側面43から先端が突出する係合突起部25と、ライニング成型面41に当接して挿入位置決めされるとともに、貫通孔の内壁面に対してかしめられている固定基部と、を有する。【選択図】図1
