Abstract
The object of the present invention is to provide an axle box suspension for a railway car with a simple structure to fix coil springs and support rubbers, and enabling easy mounting operation. Coil springs 21 and 22 are disposed on top of an axle box 10. Support rubbers 30 are disposed on front and rear portions of the axle box 10 with respect to the traveling direction of the railway car. A support shaft 31 is disposed at the axial center position of the support rubber 30, and the upper end of the support shaft 31 is passed through the side beam 6. The upper end of the support shaft 31 protruding from the upper surface of the side beam 6 is fixed via a nut. The operation of fixing the support shaft 31 to the side beam 6 by tightening the nut 40 can be performed at the upper surface area of the side beam 6, so the operation is facilitated.
