<p>PROBLEM TO BE SOLVED: To suppress influence which a flow direction of high pressure air generated from a high pressure air generating part exerts on a blowout flow direction, while suppressing increase in pressure loss, in a blower device such as an electric fan.SOLUTION: A blower device where a high pressure air generation part and a fluid element nozzle part are connected by a high pressure air passage 15 formed by a duct 14 having at least one flat surface 16 on an inner peripheral surface, includes an air flow adjusting plate 21 which protrudes toward the inside of the high pressure air passage 15 from the flat surface 16 of the high pressure air passage 15 so as not to shield an inflow port 17 of the fluid element nozzle part, and it is configured in such a manner that a local air flow in the reverse direction from the flow direction of the high pressure air passage 15 is generated by the air flow adjusting plate 21. Thus, while suppressing increase in pressure loss, influence which the flow direction of the high pressure air generated from the high pressure air generation part exerts on the blowout flow direction can be suppressed.</p> |
