When the temperature and the like change, the wire 9 is elongated, the right and left balance is lost, and the suction grill 10 is tilted and rises, first, when the leading side of the suction grill 10 comes into contact with the decorative panel 1, it stops. As the planetary bevel gear 17 continues to rotate around the bevel gear 16 on the side, the differential drive device 6 operates such that the bevel gear 16 on the rear side continues to rotate. Both sides of the suction grill 10 can be reliably closed. The quantity of the planetary bevel gear 17 is:
It can be increased or decreased to two or four according to the load of the differential drive device 6 such as the weight of the suction grille 10. If the load is light, the number of the planetary bevel gears 17 is set to two and the cost is reduced. Can be suppressed. The differential drive device 6
By using the stepping motor 19 as the driving motor for driving the motor, it is possible to perform stop control at the time of descent by closed loop control that manages the number of pulses, and to hold the suction grill 10 in the raised state with the stepping motor 19. It can depend on the holding power of the nineteen permanent magnets. By using the worm gear 18 and the worm wheel 15 meshing with the worm gear 18 in the transmission mechanism from the stepping motor 19 to the gear box 14, the holding of the suction grill 10 in the raised state of the worm is performed. The self-locking function can be relied on, and the suction grill 10 can be reliably held in the raised state.
