PROBLEM TO BE SOLVED: To provide a rail inspection device capable of efficiently inspecting the installation states of a first rail and a second rail in a width direction with prescribed accuracy regardless of the operator's skill.SOLUTION: A rail inspection device (2) comprises: a truck (20) having wheels (22); a first roller (31S) that comes into contact with a side surface (91a) of a first rail (91); a second roller (32) that comes into contact with a side surface (92a) of a second rail (92); a first position sensor (41) that detects a position of the side surface (91a) of the first rail (91) or an outer surface (31b) of a first roller (31S); a second position sensor (42) that detects a position of the side surface (92a) of the second rail (92) or an outer surface (32b) of the second roller (32); and a rotation sensor (43) that detects a rotational angle of each of the wheels (22), the first roller (31S), or the second roller (32).SELECTED DRAWING: Figure 5

    【課題】第一レールと第二レールとの幅方向における設置状態を、効率的にかつ作業者によらずに一定の精度で検査することができるレール検査装置を実現する。【解決手段】レール検査装置(2)は、車輪(22)を有する台車(20)と、第一レール(91)の側面(91a)に接する第一ローラ(31S)と、第二レール(92)の側面(92a)に接する第二ローラ(32)と、第一レール(91)の側面(91a)又は第一ローラ(31S)の外面(31b)の位置を検出する第一位置センサ(41)と、第二レール(92)の側面(92a)又は第二ローラ(32)の外面(32b)の位置を検出する第二位置センサ(42)と、車輪(22)、第一ローラ(31S)、又は第二ローラ(32)の回転角を検出する回転センサ(43)と、を備える。【選択図】図5
