具１１０の固定部１１９に固定する。The axle box supporting device 101 comprises an outer cylinder fitting 110 fixed to a bogie frame (not shown), a core body 111 also fixed to the axle box (not shown), a rubber elastic body 112, and a connecting member 114. The core body 111, the rubber elastic body 112, and the outer cylinder fitting 110 are press-fitted to each other by pushing the rubber elastic body 112 while rotating the rubber elastic body 112 in the arrow direction from a position where the 111 is separated from the outer cylinder fitting 110 by a certain distance in the axial direction. It will be assembled. FIG. 4 shows a state in which the press-fitting is completed. After the press-fitting is completed, the connecting member 114 connects the outer tubular metal fitting 110 and the core body 111. To connect the outer tubular member 110 and the core body 111 with the connecting member 114, the connecting member 114
The connecting member 114 is inserted from the upper end opening of the outer tubular metal fitting 110 with the rectangular block 113 provided at the lower end of the lower part facing downward, and the rectangular block 113 is engaged with the engaged plate 11 on the core body 111 side.
5 to match the rectangular through hole 116 of FIG.
Through in the axial direction. Rectangular block 113 is through hole 1
After passing through 16, the entire connecting member 114 is rotated by about 90 degrees as shown in FIG.
Move it 0 degrees. Then, at that position, the disc 117 provided on the upper end of the connecting member 114 is fixed to the fixing portion 119 of the outer tubular metal member 110 by the set screw 118.

ない。In this way, the rectangular block 113 cannot pass through the through hole 116 of the engaged plate 115 thereafter. Therefore, even if a force acts on the core body 111 in the pull-out direction, the core body 111 cannot move relatively in the same direction, and when the bogie frame is lifted and disassembled for a periodic inspection or the like, the core body 111 is moved to the outer cylinder part. It does not fall out of 110. Therefore, the outer cylinder fitting 110, the core body 111, and the rubber elastic body 1
There is no problem such as separation of 12 and difficulty of reassembly, and no safety problem due to dropping of the core body 111.
