PROBLEM TO BE SOLVED: To provide a track displacement measuring device capable of directly and quickly measuring displacement of one rail.SOLUTION: A track displacement measuring device 1 measures displacement of a track. The displacement measuring device comprises: an irradiation unit 21 that is fixed to one rail R and emits laser light S; a traveling unit 5 that independently travels on the same rail as the irradiation unit; and a light receiving unit 4 attached to the traveling unit. The light-receiving unit includes a PSD element unit 41 that is planar on a cross section substantially orthogonal to an extension direction of the rail and capable of detecting a light-receiving position of the laser light.SELECTED DRAWING: Figure 1

    【課題】1本のレールの変位を直接、かつ迅速に測定することが可能な軌道変位測定装置を提供する。【解決手段】軌道変位を測定する軌道変位測定装置1である。そして、1本のレールRに固定されるレーザー光Sの照射部21と、照射部と同じレール上を自立走行させる走行部5と、走行部に取り付けられた受光部4とを備えている。この受光部は、レールの延伸方向に略直交する断面において面状となってレーザー光の受光位置の検出が可能なPSD素子部41を有している。【選択図】図1
