機の回転軸支持装置。 In a blower in which an impeller is attached to the end of a rotating shaft that is cantilever-supported via a pair of bearings, an outer ring of one of the bearings is attached to the inner periphery of the end opposite to the impeller of a cylindrical bearing housing that supports the bearings. In addition to forming a stepped part that engages with the outer end face, a holding plate for the other bearing outer ring is provided on the end face on the impeller side, and this holding plate is connected to the opposite side of the impeller using a bolt that passes through the bearing housing in the axial direction. A rotary shaft support device for a blower, characterized in that the bearing is fixed in the axial direction by tightening from the side.
