PROBLEM TO BE SOLVED: To provide an air blowout device with a simple configuration which can adjust a flow direction of a blowout airflow and a degree of convergence and diffusion.SOLUTION: The air blowout device includes: a housing 21 for defining an air flow passage 22 and a blowout port 23; a wind direction adjustment plate 31 capable of adjusting a flow direction of air blown out of the blowout port; and ventilation amount adjustment plates 41, 42 capable of adjusting an amount of air passing through the air flow passage. The air flow passage includes: a first flow passage 22a opening to a blowout port central part; a second flow passage 22b and a third flow passage 22c arranged so as to sandwich the first flow passage, and opening to an outer peripheral part of the blowout port. A flow passage area of an opening end of each of the second flow passage and the third flow passage is smaller than a flow passage area of an opening end of the first flow passage. The wind direction adjustment plate is supported in the first flow passage in a rotatable manner. The ventilation amount adjustment plates can adjust a flow rate in a range from a first state for allowing the ventilation of only the first flow passage, leading to a third state for allowing ventilation of none of the first flow passage, the second flow passage and the third flow passage, via a second state for allowing all ventilation of the first flow passage, the second flow passage and the third flow passage.SELECTED DRAWING: Figure 1 |
