<p>PROBLEM TO BE SOLVED: To simplify the constitution of a flap driving means and downsize it, and smoothly drive a flap without backlash by suppressing the backlash of drive system gears. SOLUTION: A motor 51 is attached to the bottom side of a motor base 52, and also a pinion gear 54 and an output gear 55 are stored in the gear housing part 521. The output shaft 553 of the output gear 55 is coupled with a flap 30, being passed through the side plate 25L of an air blowout port, and the output shaft 553 is rotatably supported by the shaft receiving hole 526 made at the bottom of the motor base 52 and the burring hole 251 made at the side plate 25L.</p> |
