Abstract

A nozzle device 1 includes a main body 10 that is formed of a main-body first member 11 and a main-body second member 22 and that has an internal accommodation space 21 in which members are accommodated, a movable nozzle portion 30 that is accommodated in the accommodation space 21, and a coil spring 2 that is disposed between the movable nozzle portion 30 and the main body 10. When air is supplied to a main-body flow-path portion 23 from below, the flow path of the air is changed by the Coanda effect in an air guiding portion 27 such that the air flows along the air guiding portion 27, and the air flows into a gap between an air receiving portion 36 and the air guiding portion 27 and is guided to the air receiving portion 36. The air is pressurized in the air receiving portion 36 and pushes up the movable nozzle portion 30.
