To improve convenience in use of curl operation by constituting a rotary part so that rightward rotation, leftward rotation and stopping can be selected to a main body part according to operation, reducing rotational motive power of a fan of an air blowing part by rotation of the rotary part, and operating so that leftward rightward rotation can be selected.

When a curl brush 3 is installed in a rotary part 2 of a hair drier and is set usable, when hair is combed, a rotary button 4 is selectively set to fixation. In this condition, the rotary part 2 is fixed to a main body part 1 of the hair drier, and is put in an ordinary using condition of the hair drier, and hair is combed. Next, in a condition where a power source is turned on and hot air is blown out, it rotates rightward or rotates leftward at rotating speed becoming low speed rotation by a difference in a radius between a worm 6 mechanism, a rotation transmitting plate 7 and leftward-rightward rotating plates 2a and 2b to a rotary shaft 8 according to R or L of the selected rotary button 4. Therefore, when a switch is turned on in a condition where hair is curled by a curl brush 3, hair is curled while rotating the curl brush 3 round which hair is wound.
