PURPOSE:To enhance the operational ability of an air blower, by transmitting the revolution of a motor output shaft as the reciprocal turning movement of louvers, shifting the motor itself and allowing the motor to make turning movement up to the position over the range of reciprocal turning movement of the louvers. CONSTITUTION:A motor 28 for louvers is capable of making transfer between two positions on left and right sides together with a motor supporting member 22. A cam 30 for turning louvers and a cam 31 for transferring a motor are formed integrally and fixed to the output shaft 28a of the motor. The louvers 20 are turned reciprocally by the action of the cam 30a via an actuation lever 21 and the motor 28 is transferred by the action of the cam 31 so that the louvers 20 are turned up to a predetermined position over the range of the reciprocal turning movement so as to close a blow-off port 15.
