Claims

[Scope of utility model registration request]

A first bearing that provides support in the radial direction and a second bearing that provides support in both the radial and thrust directions are arranged at a certain distance from each other. The second bearing is arranged at a position slightly apart from a bearing body that supports a cylindrical-column-shaped portion near the one end of the rotating shaft, and a bearing part of the bearing body. a bearing plate for receiving a hemispherical portion formed at one end of the rotating shaft, and a boundary portion between the hemispherical portion and the cylindrical portion of the rotating shaft is connected to the bearing body and the bearing plate. A bearing device configured so that it does not come into contact with any deviation.
