Summary:PURPOSE:To reduce the level of noise, by forming an air guide by a disk part facing to the under surface of an impeller and a plurality of guide parts each of which has an inclined face, and making the height of guide part equal to or lower than the under surface of the impeller. CONSTITUTION:An air guide 19 is made up of a guide part 30 having a disk part 27 facing to the under surface of an impeller 21, a cylindrical part 29 forming the outer circumference thereof, a flat part 31, and inclined-face parts 28. The guide part 30 is placed in the position equal to or lower than the under surface of the impeller 21, so that the impingement of air current from the impeller 21 to the guide part 30 can be eliminated. Thus, the flowing efficiency can be enhanced with low noise.
