To provide a railway wheel that can measure a tread shape while grasping a position in a circumferential direction and suppresses cost, time and effort.SOLUTION: A railway wheel 1 travels on a rail. The railway wheel 1 includes an annular rim part 2. The rim part 2 includes: a tread 2A coming into contact with the rail; and a side surface 2C crossing with the tread 2A. The side surface 2C has an uneven pattern 4 of which cross-sectional shape at a virtual surface including a rotation axis P1 of the rim part 2 varies in a circumferential direction of the rim part 2.SELECTED DRAWING: Figure 1

    【課題】コスト及び労力を抑制しつつ、周方向の位置を把握しながら踏面形状を測定できる鉄道車輪を提供する。【解決手段】本開示は、レール上を走行する鉄道車輪1である。鉄道車輪1は、円環状のリム部2を備える。リム部2は、レールと接触する踏面2Aと、踏面2Aと交差する側面2Cとを有する。側面2Cは、リム部2の回転軸P1を含む仮想面での断面形状がリム部2の周方向に沿って変化する凹凸パターン4を有する。【選択図】図1
