The present invention makes nozzles attached to the end of an outlet of a hair dryer automatically move from side to side such that wind directions can be conveniently changed without shaking wrist or the arm of a user during drying hair, and thereby, reducing fatigue of the wrist joint, shoulder joint and muscle for not only people engaged in beauty and hair businesses but also people at home when using the hair dryer. The present invention discharges air sucked from a blower fan (10) through a nozzle of the outlet (20) as it is, or discharges the air by heating with a heater (40) installed in the inside of the outlet (20). In order that the nozzle (30) can move from side to side at the end of the outlet (20), a rotating shaft (50) is formed in the upper and lower parts of the nozzle (30) and a pinion (60) is formed by shaft coupling with the rotating shaft (50). Additionally, a rack gear (70) is formed by gear coupling with the pinion (60), wherein the rack gear (70) performs a reciprocating motion by a driving unit (80) so as to rotate the pinion (60) from side to side by the reciprocating motion of the rack gear (70), and thereby, rotating the nozzle (30) from side to side. |
