ABSTRACT:
A vane driving device includes: two boards each having an opening and defining a blade chamber therebetween; a blade changing an area of the opening and housed in the blade chamber; a drive source for driving the blade, the drive source including: a coil winded around a stator and exciting a stator; a rotor rotatably supported by a rotary shaft, rotatable in conjunction with the rotary shaft, and magnetized to have different polarities in a circumferential direction; and a rotor pinion meshing a driven member, and integrally formed in the rotary shaft; and a printed substrate electrically connected to the coil. The two boards define a drive source chamber housing the drive source therebetween. At least one of the two boards has an opening for escaping the coil outwardly from the drive source chamber. The printed substrate is arranged on a outer wall surface opposite to the drive source chamber.
