Abstract: A hair drying device includes a blower unit incorporating a fan and a heater for generating a hot air blow and provided at its one end with an air outlet for discharging the hot air blow. The blower unit is pivotally supported to a frame which is adapted to be mounted in or on a generally vertical wall of a room for pivotally supporting the blower unit at the other end about a horizontal axis so that the blower unit is capable of moving about the horizontal axis within a predetermined angular range between a retracted position of directing the air outlet generally vertically downwardly and an extended position of directing the air outlet outwardly and downwardly. A start position is provided offset adjacent to the retracted position so as to define within the angular range a swing range extending from the start position to the extended position. The blower unit is driven to swing within the swing range about the horizontal axis in a reciprocating manner.
