To provide a tunnel carriage wheel that allows a tunnel carriage to move smoothly on a standard rail simply installed in a tunnel.SOLUTION: A wheel 2 of the invention is placed on a standard rail 1 and supports a tunnel carriage V so as to be movable along the standard rail 1 with a central portion 14 of a top surface of a head 13 forming a convex curved surface having a relatively large curvature radius R1, and with both side edges 15, 16 of the top surface of the head 13 having relatively small curvature radii R2, R3, respectively. An outer peripheral surface 21 of the wheel 2 is formed to be a concave curved surface having a radius curvature same as the curvature radius R1 of the central portion 14 of the standard rail 1.SELECTED DRAWING: Figure 3

    【課題】トンネル内に簡易に設置した規格レール上をトンネル用台車が円滑に移動可能としたトンネル台車用車輪を提供する。【解決手段】頭部13頂面の中央部14が相対的に大きい曲率半径R1の凸曲面をなすとともに頭部13頂面の両側縁部15,16が相対的に小さい曲率半径R2,R3の凸曲面をなす規格レール1に載置されてトンネル用台車Vを規格レール1に沿って移動可能に支持する車輪2であって、車輪2の外周面21を、規格レール1の中央部14の曲率半径R1と同一曲率半径の凹曲面に成形する【選択図】 図3
