る。In the single-axle bogie for a railway vehicle according to the present invention, a pair of links connecting the vehicle bodies is connected to a wheel axle in which the right and left wheels are integrally fitted to the axle. Even if the axle is displaced to the outer track side due to centrifugal force due to the gradient of the tread surface, as shown in FIG. 10, the diameter 2Rout of the wheel 6 on the outer track side is in contact with the rail 8 due to the lateral displacement toward the outer track side. On the inner track side, conversely, the diameter 2Rin of the wheel 6 becomes smaller, and the wheel set returns to the center of the track as a self-action. As a result, it is possible to prevent the deviation to the outer track side, which has occurred in the case of the independent rotating wheels. As a result, it is possible to prevent a deviation to the outer track side when traveling on a curved road while maintaining the steering action on the single-axle bogie for the railway vehicle.
