PURPOSE:To improve the air screening performance at the time when louvers are fully closed by constructing a car ventilator grill with a number of louvers so that the louvers can be mutually offset right and left centering a rotary shaft and adjacent louvers can mutually be surface-contacted and overlapped when they are fully closed. CONSTITUTION:Louvers 21 are formed with blade sections 21a and 21b that are stretched mutually in the reverse direction adjoining a pin support section 15 and are offset mutually by means of step sections 26 and 27. When the louvers 21 are revolved using a knob 22, all louvers 21 are integratedly revolved by means of a connecting rod 23. When the louvers are fully closed, they are contacted mutually and both ends louvers 21 are formed so as to touch the inner wall surface of a case 20. As a result, when the louves 21 are fully closed, the air screening performance can be improved. |
