PURPOSE: An automatic rotary type air vent structure is provided to realize uniform air cooling and heating by automatic rotation, thereby increasing the convenience of users and improving the quality of a vehicle. CONSTITUTION: An air vent housing(10) is combined with an air vent grill(11) in a front part. A driving element is formed on a side of the air vent grill for automatically rotating vertical blades(12a) and horizontal blades in all directions. The driving element is formed of a motor driving part(20), a gear part, and a link part. The motor driving part generates motive power. The gear part and the link part transmit motive power of a motor to the vertical blades and the horizontal blades. When the motor is driven, the vertical blades and the horizontal blades are automatically repeatedly operated.
