Abstract
PURPOSE: To permit smooth normal and reverse revolutions of a rotary grille by allowing the projections of the rotary grille to be obstructed by obstructing pieces and preventing immediate reversal of the rotary grille due to the reversal of a synchronous motor.
CONSTITUTION: On the outer periphery of a rotary grille 5, projections 6 are formed, and when the rotary grille 5 revolves, revolution is obstructed by the obstructing pieces 7 mounted on a supporting body 1 and the rotany grille 5 revolves reversely. An engaging pin 9 is fixed on the output shaft 8 of a synchronous motor 4, and engages with the engaging groove 11 of the shaft part 10 of the rotary grille 5, and the engaging groove 11 is made larger in the direction of revolution than the engaging pin 9, so that rorary grille 5 does not start reversal immediately.
