いる。Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, a blower 2o is housed in a casing 19. A filter 22 is located on the leeward side of the casing 19, and the upper end 21a of a filter frame Z attached to the outer periphery of the filter 22 and the lower surface of the casing 19 are directly connected by a connector 16. A hole 17 provided at the lower end 21b of the filter frame 21 is a hole for operating the connector 16 during assembly and maintenance, and a hole 18 connects the casing 1 of the blower 2 and the upper end 21a of the filter frame 21 with the connector 16. After that, the hole 17 is closed. The lower end 21b of the filter frame 21 is bent upward.
