Claims

[Scope of utility model registration request]

A circular baffle plate is installed at the step between the joint surface of the stator frame and the bearing bracket, with an opening in the center and an arc-shaped protrusion in the circumferential direction of the outer periphery, with the inner and outer peripheries of this protrusion being flat. In the air guide plate of a rotating electric machine which is held in place, a semicircular protrusion is integrally formed from the same material in a direction opposite to the protrusion so as to be held between the protrusion and the flat part of the air guide plate. Wind guide plate.
