In order to provide an air shower apparatus having good usability and high dust removing efficient, a nozzle for blowing out air is constructed to comprise a first body structure provided with a first air flowing path guiding air from a filter side to an air shower chamber side and with a second air flowing path in communication with the first air flowing path at mutually opposite positions on a side wall thereof, and a second body structure rotatably supporting the first body structure, wherein part of air sucked into the first air flowing path flows through the second air flowing path to cause a pressure difference between regions where the second air flowing path intersects with the first air flowing path and by change of the pressure difference with time, a flow direction of air flowing through the first air flowing path is varied with time.
