ABSTRACT:
A flow of air from an air discharge passage has its direction of flow controlled by a series of louvers arranged to swing horizontally back and forth. Each louver has a hinge pin rotatably supported to form an axis of rotation. A connecting member interconnects a plurality of the hinge pins to transmit rotational movement between those hinge pins. The connecting member is attached to each hinge pin by a flexible connection enabling the hinge pin to rotate relative to the connecting member. The connecting member is disposed within a member which shields the connecting member from the air flow.
