PURPOSE:To prevent degradation of maintenance capability due to trunnion shaft stuck to a trunnion bracket by providing trunnion shafts located on both sides of a vehicle in a slidable manner to the trunnion brakets by means of bearings, and enabling separate disassembly of the trunnion shaft and bearing on each side. CONSTITUTION:A trunnion shaft 4 provided with a spring seat 22 on one end is fitted in a slidable manner into a fitting hole 25 which is formed in a trunnion bracket 7 through a pair of bearings 23. The other end of the trunnion shaft 4 is fixed to the trunnion bracket 7 in the axial direction by means of a stopper plate 24 whose peripheral part is brought into contact with the trunnion bracket 7 and a bolt 26. Further, there is provided inside the trunnion bracket 7 a supporting frame 20 by means of bolts and the like so that the trunnion bracket 7 on each side may be fitted stably to the frame. This constitution allows the trunnion shaft 4 to be easily withdrawn from the trunnion bracket 7 by removing the bolt 26. |
