To reduce a decrease in a wheel load on the outer rail side of the front axle that occurs when traveling at low speed, particularly in an exit easement curve section. A bogie for a railway vehicle having a bogie frame 22 supported by axle springs 10 disposed on axle boxes 9 which rotatably support a wheel set 7, with air springs 4 disposed on both sides of the railway vehicle in a width direction of the bogie frame, each of the air springs 4 being provided with an automatic height adjusting device 6 for maintaining a constant height of a vehicle body 5 which is supported by the air springs 4. The axle boxes 9 are disposed at positions closer to the center side of the railway vehicle in the width direction than the wheels 7b attached to both sides of a shaft 7a which constitutes a wheel set 7, and a height detection position of the automatic height adjusting device 6 is detected at a position between an axial center of the air springs 4 and an axial center of the axle springs 10. It becomes possible to improve the ability to pass through exit easement curve sections. |
