Provided is a blower configured so that a frame and a shutter shaft part, which is provided with a shutter shaft, can be easily affixed to each other, thereby enabling the blower to be assembled with good work efficiency. This blower is provided with: a frame 200; tilted protrusions 211 protruding from an inner surface of the frame 200 and forming an acute angle relative to the inner surface; an elongated shutter shaft part 300; a shutter shaft 311 provided to the shutter shaft part 300 and protruding perpendicularly from a first shaft part surface which is parallel to the longitudinal direction of the shutter shaft part 300; and tilted shape sections 312 provided at the opposite ends of the shutter shaft part 300 and forming an acute angle relative to a second shaft part surface on the reverse side of the first shaft part surface. The blower is characterized in that the shutter shaft part 300 is affixed to the frame 200 while the inner surface of the frame and the second shaft part surface are in contact with each other and the tilted shape sections 312 are located between the inner surface of the frame 200 and the tilted protrusions 211. |
