PROBLEM TO BE SOLVED: To provide an air supply hood mounted to a roof or a wall to be used as an intake port of natural wind, capable of preventing ingress of rainwater into an inflow opening while the entire inflow opening is covered with wind collecting hoods to prevent ingress of rainwater into the inflow opening, having a ventilation opening enabling inflow of natural wind to the inflow opening and capable of preventing ingress of rainwater into an indoor side when it rains. SOLUTION: The plurality of wind collecting hoods 2 are provided to cover the inflow opening 1, and by operation of the wind collecting hoods 2 by a motor 3 installed at ends of the wind collecting hoods 2, the inflow opening 1 is covered. Thus, when it rains or snows, while the wind collecting hoods 2 cover the entire inflow opening 1, ingress of rainwater into the inflow opening 1 can be prevented. Since the ventilation opening 4 enabling inflow of natural wind to the inflow opening 1 is provided, this air supply hood can prevent ingress of rainwater into the inflow opening 1 and ingress of rainwater into the indoor side.
