The above-mentioned prior art does not have a structure in which workability is taken into consideration when disassembling the bogie, that is, removing the wheel axle from the bogie frame. For example, at the time of removing the tread surface of the wheel, after disassembling the shaft spring device formed between the shaft box body and the bogie frame,
I was working. This disassembling work will be described in detail with reference to Figs. 4 and 5. First, as the disassembling work, as shown in Fig. 4, a method of removing the mandrel 5 at a press-fitting portion of the mandrel 5 to the roll rubber 4, and a fifth method. As shown in the figure, there are a method of removing the mandrel 5 at the attachment portion to the shaft box body 2 and a method of removing it at the attachment portion between the outer cylinder 3 and the bogie frame, but it is detached at the attachment portion between the outer cylinder 3 and the bogie frame. Since the method is not usually applied from the viewpoint of workability, it will be omitted from the following description. However, in the method shown in FIG. 4, since the inner peripheral surface of the outer cylinder 3 is formed into a conical shape and the roll rubber 4 is press-fitted into the inner peripheral surface of the inner cylinder 3, the force input by the mandrel 5 is When it disappears, the roll rubber 4 moves toward the large diameter side of the outer cylinder 3, that is, outward, as shown by the dotted line in the figure, and sticks out from the end of the outer cylinder 3. In the worst case, the roll rubber might come off from the outer cylinder 3.

Therefore, if the roll rubber 4 protrudes from the outer cylinder 3 as described above, the position of the roll rubber may be displaced during reassembly to change the support height of the shaft spring device or the elastic support characteristics. . In particular, if the support height of the entire shaft spring device changes, the desired roll rubber characteristics may not be obtained, and there is a risk of deterioration in riding comfort and running stability.

By forming the cylindrical portion on the large diameter portion of the inner peripheral surface of the outer cylinder and forming the cylindrical portion on the tip of the mandrel, the shaft of the roll rubber and the shaft is separated from the roll rubber as the wheel shaft and the bogie frame are separated. Since an unnecessary pushing force does not occur between the cylindrical portion and the cylindrical portion and the roll rubber when the external force in the direction is not applied, these are fitted to each other before each separation. The positional relationship can be maintained and the assembly work can be performed easily. Further, the cylindrical portion and the columnar portion are simple in structure only because they are formed on a surface parallel to the axial center of the outer cylinder and the mandrel.

The size of the projection 9 is such that, in a state where the roll rubber 4 is press-fitted into the outer cylinder 3 and is not subjected to any other force, it overcomes the outward movement force generated by the restoring force of the roll rubber 4 itself. It should be large enough to generate a holding force. On the other hand, the protrusion 9 also needs to have a size that allows the roll rubber 4 to be easily press-fitted into the outer cylinder 8. by the way,
In the figure, the protrusion 9 is formed on the entire circumference, but there is no problem even if it is installed intermittently.

Next, FIG. 2 shows another embodiment of the present invention, in which 12 is an outer cylinder attached to the bogie frame in the same manner as the conventional outer cylinder.
The inner peripheral surface is formed in a conical shape. Further, a large-diameter portion of the inner peripheral surface of the outer cylinder 12, that is, a portion near the edge of the outer cylinder 12 has a surface parallel to the axial center thereof, and has an inner diameter capable of holding the roll rubber 4. A cylinder 13 is provided. The inner diameter of the cylinder 13 does not change in the axial direction thereof, and the roll rubber 4 is moved to the outside of the outer cylinder 12 by the restoring force of the roll rubber 4 itself in the state where the external force in the axial direction of the roll rubber 4 is not applied. Since it is formed to have an inner diameter that can be retained, no outward movement force is generated.
