Thus, even if the bridge axes of the bridge girders 10 and 20 are slightly shifted, the distance between the bridge girders 10 and 20 can be detected. In addition, since the traveling speed of the laser does not change due to a difference in temperature or the like, the distance between the bridge girders 10 and 20 can be accurately detected by the laser distance meter. The reflecting plate 46 is attached to the bridge girder 20 side, and the ultrasonic distance meter 47 and the laser distance meter 48 are used.
