Abstract

PURPOSE: To make an easy flow of cooling air with a cooling effect heightened, also with a generation of noise prevented, by means of providing a slope, toward the side of a front bracket, in inside end edge of a fan blade of cooling fan installed outside the front brasket with a ventilation window provided.
CONSTITUTION: Inside end edge of a fan blade 11 of cooling fan 10, enaged in the rotary shaft at the outside of a front bracket 2, is made into a sloped end edge 14, further with a distance of end part 15 of the slope end edge 14 from the rotary shaft made to be agreed with a distance of a peripheral edge 16 of ventilation window from the rotary shaft. In this way, when a cooling air, that enters from a ventilation window 13 of a rear bracket 3 to cool a rotor 6, is flowing toward the cooling fan 10 from a ventilation window 12 of the front bracket 2, no turbulence will be generated in the flow, causing a cooling effect to improve simultaneously a reduction capable for a generation of noise.
