The present invention provides a displacement measuring device for a rail in a width direction. The displacement measuring device comprises a pair of rail fixing members (100) which is fixed while surrounding the lower part of a double-sided rail (10); a sensor casing (200) whose both ends are coupled to hinge coupling units (101) of the pair of rail fixing members (100) by a hinge to be driven in response to the relative subsidence of the double-sided rail (10); and an angle sensor which is installed on the sensor casing (200) to measure an angular change of the pair of rail fixing members (100). The displacement measuring device can be applied to a sleeper tie made of a concrete material, have the high reliability of data by measuring the displacement of the rail directly, and measure the occurrence of a height difference of the double-sided rail. |
