Abstract: A thin air outlet structure to a vehicle compartment exhibiting excellent directivity while ensuring sufficient volume and velocity of air conditioning air stream. In the air outlet structure 10, delivery direction of the air stream can be altered by altering the posture of a pair of fins 16 provided at a middle portion 13 in the flow direction in a case 12.
