PROBLEM TO BE SOLVED: To provide a ventilation grill capable of selecting any of left or right as ventilating directions, and of effectively making a drain hole to function to drain water irrespective of selected pumping directions. SOLUTION: A plurality of blade plates 21a are provided in a louver 2 for rectifying air supply/exhaust air only in one direction of left and right, and drain holes 22a, 24a serving as drain are drilled in upper and lower portions of the louver. Accordingly, if the louver is turned and mounted upon mounting of a ventilated grill 1, then an arbitrary supply/exhaust air direction needed in response to a mounting position can be selected. Even when any supply/ exhaust air direction is selected, the drain holes 22a, 24a can be positioned at a lower portion of the ventilated grill 1, and hence rain water invades into the ventilated grill and condensed water flows into a duct hole, the drain holes 22a, 24a can be made to effectively function for draining. |
