Abstract

PURPOSE: To prevent the back-flowing of wind from the engaged portion between the supporting portion of bearings and a cylindrical portion and to increase the efficiency of vertilation by pressure-inserting the cylindrical portion of a fixed guiding plate into the periphery of the supporting portion of bearings.
CONSTITUTION: The cylindrical portion 34 of the fixed guiding plate 16 is insterted into the periphery of the supporting portion of bearings. By so doing, when the air is introduced to a electric motor 1 from a ventlating hole 34 through the ventilating passageways of a diffuser 31 and return guide vane 32, using a fan 15 driven by the motor 1, the back-flowing of the air from the engaged portion between the supporting portion 14 of bearings and the cylindrical portion 34 can be prevented while improving the efficiency of ventilation.
