PROBLEM TO BE SOLVED: To make the position of a beam parallel to a car body frame to improve the durability of an air spring by mounting the beam to an axle case through a mounting-assembly body having caster plate. SOLUTION: An axle case 13 is connected to a car body frame 2 at an angleθof intersection, which corresponds to the tilt angle of a propeller shaft. The mounting of a beam 24 to the axle case 13 is performed through a mounting- assembly body 25 surrounding the periphery of the axle case 13. Since a caster plate 90 having an inclined plane inclined at the tilt angle which corresponds to an angleθof intersection, is interposed between the axle case 13 out of mounting-assembly body 25, and the beam 24, the beam 24 is mounted to the axle case 13 in a position parallel to the car body frame 2. |
