している。2. Description of the Related Art There are railroad container cars, tank cars, hopper cars, etc. in which a wheel shaft is rotatably supported by a roller bearing using a cylindrical roller or a conical roller. The roller bearings are removably stored in a shaft box that is mounted on a trolley such as a container car, and if a malfunction such as shaft burn occurs due to long-term use, it will cause a serious accident. During regular inspections (hereinafter referred to as "full inspection"), the roller bearings are taken out of the housing, disassembled, and cleaned before dimensional inspection. When the size of the roller bearing is out of the standard, the roller bearing is repaired, and when the roller bearing cannot be repaired, the roller bearing is replaced with a new one, and the roller bearing is mounted on the axle box again.

悪いという課題もあった。However, in such a conventional roller bearing extracting device, the axle box 1 and the hydraulic ram 5 are centered in an unstable state in which the device body 3 is suspended by the crane 9. Since it has to be performed, not only is it difficult to set the shaft box 1 and it takes a long time to perform the centering work, but also when the hydraulic ram 5 is driven, the pushing jig 7 is easily disengaged from the roller bearing 6, so that the pushing jig 7 can be used. There was a problem that the cage and its holder are easily damaged. Further, since the crane 9 for suspending the apparatus main body 3 is required, not only the extraction work place of the roller bearing 6 is limited, but also it is necessary to manually transport the roller bearing 6.
It is said that the worker must carry a heavy object that is dirty with grease etc. and becomes slippery by hand, forcing the worker to perform dangerous work for a long time, resulting in poor work safety and efficiency. There were also challenges.
