Abstract
A blower fan unit includes a housing, a fan, a support unit to support the housing rotatably, and a exhaust tube projecting from the outlet, the exhaust tube producing a reaction force by guiding the airflow toward an upstream side of movement of the peripheral surface synchronized with rotation of the housing, the reaction force rotating the housing toward a downstream side of the movement of the peripheral surface of the housing, a stopper being positioned on a movement path of the exhaust tube that moves with the rotation of the housing to stop the rotation of the housing by blocking movement of the exhaust tube, and a switch mechanism to switch blocking and restarting of the movement of the exhaust tube using the stopper.
