A plurality of openings 46 are provided on the outer circumference of the motor 25 when viewed from the front. Thereby, when the blade 19 rotates, a part of air is sucked into the motor cover 24 from the gap L <b> 1, and an airflow flowing into the blade 19 through the opening 46 of the one side surface 45 is generated. With this air flow, the temperature rise of the motor 25 in the motor cover 24 can be reduced. Further, since this air flow enters the motor cover 24 along the outer surface of the motor cover row 47, the air flow flows along the inner surface of the motor cover 24 and flows so as to cover the motor unit 22, so that the temperature of the motor 25 rises.

Thus, the motor holder 23 rotates around the pivot 16 of the motor holder 23 in the fixed cover 14, and the air blowing means and the vertical swinging means are reciprocally rotated in the horizontal direction, that is, the left-right direction. The upper strut portion 5 is moved up and down by the left and right swinging means, but is fixed without swinging and swinging back and forth, that is, horizontal swing, that is, horizontal swing, vertical swing, that is, vertical swing. I do not.

  When the crank 42 is rotated by the stepping motor 41, the motor holder 23 is placed in a certain angle range that is uniquely determined by the relationship between the length of the fixing portion 33 and the link 43 and the pitch fixed by the screw of the crank 42 or the like.
