摘要： PROBLEM TO BE SOLVED: To realize measurement of a horizontal pressure over a long period of time at a business line. SOLUTION: In the method for measuring the horizontal pressure generated on a wheel 4 of a railway vehicle, a non-contact displacement meter 3 is arranged on a shaft box 2 for rotatably supporting a wheel shaft through a bearing 1. During traveling, a displacement amount of a rim part 4a or a plate part 4b of the wheel 4 is measured by the displacement meter 3. The horizontal pressure is determined from the measured displacement amount and a previously determined conversion value of the displacement amount and the horizontal pressure of the rim part 4a or the plate part 4b of the wheel 4. Accordingly, since a measurement signal is not taken out from the rotating wheel shaft but a signal is taken out from the non-contact displacement meter mounted to a member for rotatably supporting the wheel shaft through the bearing, measurement of the horizontal pressure generated on the wheel can be easily performed on the business line without using a slip ring and an FM telemeter over a long period of time.
