Zusammenfassung:An air sending device includes: a housing; a fan motor; a fan configured to generate an air current; a motor support base provided upstream of the fan and the fan motor in a flow direction of the air current, and supporting the fan motor; and a rectifying member provided upstream of the motor support base, protruding in a direction from the motor support base toward the upstream side, and having a rectifying surface configured to change the flow direction of the air current such that the air current flows toward an inner circumferential region of the fan. The rectifying surface of the rectifying member includes an upstream-side distal end surface formed spherically, and a main surface located between the upstream-side distal end surface and the motor support base, forming an outer peripheral surface of the rectifying member, and tapered in a direction away from the motor support base.
