Claims

[Scope of utility model registration request]

(1) The wind direction plate of the air outlet is automatically oscillated in accordance with the reciprocating movement of a pneumatic operating mechanism that is activated depending on whether or not air pressure is applied, and the mechanical movement is made in accordance with the movement of the wind direction plate. cyclically discharging air pressure from a pneumatic source applied to the pneumatic actuating mechanism to the atmosphere by a response valve consisting of a piston cylinder operated by the pneumatic actuating mechanism;
In the wind direction plate driving device which applies and non-applies pneumatic pressure to the pneumatic actuating mechanism in a walking manner, an orifice is provided on the pneumatic flow path between the pneumatic actuating mechanism and the response valve, and the pneumatic actuating mechanism The mechanism is characterized in that a sudden change in air pressure in the mechanism is alleviated, and a pressure accumulation means is provided between the orifice and the response valve, so that the air pressure from the air pressure source is temporarily stored in the pressure accumulation means. A wind direction board drive device for the serious air outlet.

(2) The device according to claim 1, wherein the pressure accumulating means is a surge tank.

(3) The device according to claim 1 or 2, wherein the orifice and the pressure accumulating means are constructed separately or integrally.
