PROBLEM TO BE SOLVED: To provide an air-blowing mechanism in which decrease of air quantity is suppressed in an air channel on which an opposing wall-shaped obstacle is present directly under an axial-flow fan.SOLUTION: A air-blowing mechanism comprises a rectification member A which is provided in a device, including an axial-flow fan 1 including a shaft part having a circular surface at an end part in a shaft direction thereof and a blade provided at the shaft part, and a wall-shaped air-channel obstacle 7 provided so as to oppose the axial-flow fan, and adapted to rectify flow of air. The rectification member has a truncated cone shape having a first circular surface A1 and a second circular surface A2 having an area equal to or larger than that of the first circular surface, the first circular surface is the same as the circular surface of the shaft part in shape and area, and the first circular surface is provided on the air-channel obstacle in such a manner as to oppose the circular surface of the shaft part. |
