PROBLEM TO BE SOLVED: To prevent damage of a lead wire while avoiding complication of an internal structure of a head part.SOLUTION: A head part 2 has a U-shaped plate including a pedestal (front plate) 27 fixed on a front surface of a fan motor 23 and two plate parts (side plates) 28, 29 extending backward from both left and right sides of the pedestal 27 and located on both left and right sides of the fan motor 23. A base for supporting the head part 2 in a manner rotatable in a vertical direction includes a U-shaped arm 11 having two extension parts for sandwiching the head part 2 from both left and right sides when viewed from a front and back direction. The U-shaped arm 11 is supported by the plate parts 28, 29 of the U-shaped plate via a rotary shaft (shaft 34) related to the rotation in the vertical direction. A vertical oscillation mechanism 24 is arranged in a space formed by the U-shaped plate, and includes an oscillation motor 31 having a rotary shaft penetrating one side plate 28, and mechanism parts (gears 32, 33) arranged between the one side plate 28 and one extension part, driven by the oscillation motor 31 and for allowing the head part 2 to oscillate in the vertical direction with respect to the base.SELECTED DRAWING: Figure 3 |
