Abstract
PURPOSE: To reduce noise by providing a cutout opening part which is shaped by removing a part of the circumferential wall of an outer frame in the proximity of rotating vanes.
CONSTITUTION: The outer frame 5 consists of the first flange part 51, the second flange part 52, a connecting member 53 connecting the two flange parts 51 and 52, the circumferential wall surface 54 close to the rotating vanes, and the cutout part 55 in the form of a space produced by removing a part the wall surface 54 while leaving the connecting member 53. The noise of turbulent flow generated between the vanes and the circumferential wall surface of the outer frame in the periphery of the vanes can be reduced by removing a part of the wall surface as opening.
