WIPO Patent Application WO/2024/014014

A1

The purpose of the present invention is to stabilize the position where a fan casing and a housing are secured to one another.　The present invention is equipped with: an impeller 211 which is rotated and driven by an electric motor unit 250; an impeller-side housing 212 which covers the outer circumference of the electric motor unit 250; and a fan casing 230 which is connected to the impeller-side housing 212. The impeller-side housing 212 is equipped with a first projecting part 220. An L-shaped notch section 234 is formed in the fan casing 230 and is notched toward the impeller 211 side from the side thereof which is connected to the impeller-side housing 212, and is also notched so as to extend in the circumferential direction of the fan casing 230. The fan casing 230 and the impeller-side housing 212 are connected by inserting the first projecting part 220 from the side of the notch section 234 which is connected to the impeller-side housing 212, and thereafter, rotating the fan casing 230 in the circumferential direction and moving the first projecting part 220 to the position of the notch section 234 which extends in the circumferential direction.
