A swing mechanism for swinging is mounted so as to collectively fit in the component storage space 16. Specifically, as shown in FIG. 3, the motor 4 is screwed to the standing surface 13, the condenser 18, the relay 19, and the relay case 20 are fixed to the mounting surface 14 by screws.
Is available. The motor 4 has a built-in reduction gear, and its rotating shaft is pulled out from a notch 21 formed on one edge of the rising surface 13 to the fan casing 1 side, and a crank 22 of a swing mechanism is mounted on the shaft end side. Have been. A swing rod 23 is connected to the crank 22,
The connection rod 24 connected to the swing rod 23 is connected to the two fan casings 1, and the two fan casings 1 swing by a single motor 4 to change the wind direction. The parts storage space 16 and the motor 3
The whole is covered with a drive unit cover 25 which is detachably configured.

The mounting of the electric parts and the like on the mounting plate 15 is performed before the mounting plate 15 is mounted on the spacer 11 of the outer shell 8 of the motor 3 and the main electric wiring is completed. It can be handled in the same manner as a circuit board on which components are mounted, and is simpler in work than mounting electrical components and electric wiring in a narrow space, simplifies the wiring route, and has good workability. Almost the entire output shaft 7 extending from the outer shell 8 is covered with the protective sleeve 9, and the protruding end side of the protective sleeve 9 is supported by the mounting plate 15 through the fitting hole 17, so that the output shaft 7 is in a double-supported state. Therefore, even if an external force acts during transportation or the like, the protective sleeve 9 prevents the swing and prevents deformation or deformation.
