PROBLEM TO BE SOLVED: To provide a blower which can respond to various use patterns and of which storage space can be reduced as much as possible. SOLUTION: In the blower comprising a radial impeller 1 and a fan casing 2 with a suction port 3 opposing to the radial impeller 1, the fan casing 2 is provided with two air flow passages 6, 7 guiding an air flow blown out from the radial impeller 1 to the centrifugal direction to two air outlets 4, 5. A flow passage opening/closing means 8 for selectively opening/closing the two air flow passages 6, 7 is provided, such that an air flow blown out from the one radial impeller 1 to the centrifugal direction is guided to selected one of the two air outlets 4, 5 via selected one of the two air flow passages 6, 7.
