PROBLEM TO BE SOLVED: To accurately measure an inclination of a train together with compensating a deviation of a measuring position by fluctuation in traveling speed of the train, by measuring an unevenness shape formed at the bottom plane of a linear motor(LIM) vehicle by a laser sensor to compute a LIM gap based on measured data of the unevenness shape. SOLUTION: A measurement is started by automatically detecting approach of a vehicle in traveling by photoelectric sensors 85, 86 placed at vehicle detecting sensors 80, 81. A gap measuring part 40 receiving the vehicle detecting signal, starts a LIM gap measuring by laser sensors 61, 62 of a gap sensor part 60. The laser sensors 61, 62 measure a distance to an unevenness plane on an unevenness part formed at the lower plane of the LIM. Measured data are received by the LIM gap measuring part 40, and measured results are edited by a measuring part processing device 41. Then, the edited data are transferred to a LIM gap operating part 20, and data of the measured results are displayed on a CRT 22 together with storing them into a database of an operating part 20.
