Claims

[Scope of utility model registration request]

In a bearing structure for a rotating body that rotatably supports a rotating shaft of a rotating body when the rotating body is rotatably attached to a predetermined location of an electrical equipment housing, a bearing portion into which the rotating shaft of the rotating body is inserted. A rotating body characterized in that a high viscosity fluid is interposed between the rotating body and the tip of the rotating support shaft, and the resistance generated during rotation of the rotating body is adjusted by the shape of the tip and the viscosity of the fluid. Bearing structure.
