PROBLEM TO BE SOLVED: To provide a polishing piece for railway vehicle, capable of maintaining high compression intensity and high foreign matter removal function.SOLUTION: A polishing piece (1) for railway vehicle of the invention is a polishing piece for contacting a wheel tread of a railway vehicle and cleaning the wheel tread. On a polishing face side, one or more groove parts (2,3) facing a width direction, are formed, in which one of the groove parts (2,3) is continuous to a side face of the polishing piece (1), and the other of the groove parts (2,3) is blocked with a base material of the polishing piece (1). The groove parts (2,3) are partial grooves, parts to which the base material of the polishing piece is continuous, are reinforcement parts (4,5), and foreign matters which are peeled by the polishing face, are removed from the side face part on which the grooves open. Therefore, high compression intensity and high foreign matter removal function, are maintained.SELECTED DRAWING: Figure 1

    【課題】圧縮強度を高く維持し、異物除去機能を高く維持できる鉄道車両用研摩子を提供する。【解決手段】本発明の鉄道車両用研摩子(1)は、鉄道車両の車輪踏面に接触して前記車輪踏面を清掃するための研摩子であり、研摩面側には幅方向に向いた一個以上の溝部(2,3)が形成され、溝部(2,3)の一方は研摩子(1)の側面までつながり、溝部(2,3)の他方は研摩子(1)の基材によって遮られている。溝部(2,3)は部分溝であり、研摩子の基材が連続している部分は補強部(4,5)となり、溝があいている側面部分からは研摩面によって剥ぎ取られた異物が除去される。この結果、圧縮強度を高く維持し、異物除去機能を高く維持できる。【選択図】図1
