ABSTRACT:
A door driving system includes a door for controlling an air flow, a transmission mechanism for operating the door, and a driving motor for exerting a rotation force at the transmission mechanism. The door has a body portion and a rotation portion, which has an approximate cylinder shape and is integrally rotatable with the body portion. The transmission mechanism converts the rotation force of the driving motor to an axial force in an axis direction thereof, and then converting the axial force to a driving force for rotating the rotation portion. The transmission mechanism is arranged at an inner side of the rotation portion. The driving motor is constructed of a DC motor. Accordingly, the door driving system is compact and light.
