The present invention measures the amount of wear of a flange of a rail-vehicle wheel directly and online during travel along a curved section. A laser rangefinder 3 is provided to the outside of a circular-curve section of a railway track. When a vehicle travels along the circular-curve section, the laser rangefinder 3 is used to measure the distance to the front rim surface 1rf of the wheel 1sfo on the outside of the track in the wheelset Sf in front in the advancement direction of a truck B composing the vehicle. This measured distance is compared with the previous measurement of the same distance to obtain the amount of flange wear. During traveling, the amount of wheel flange wear during travel along a curved section can be managed, wheels having a flange wear amount exceeding a management range can be discovered quickly, and safety when a rail vehicle travels along a curved section can be ensured.
