PROBLEM TO BE SOLVED: To provide a blow port for performing improved air control. SOLUTION: The blow port comprises a cylindrical blow port body 2 having a downstream-side opening formed in an exhaust port 6, an air direction adjusting means 10 provided in the blow port body 2 apart from the exhaust port 6 for adjusting the direction of air to be exhausted from the exhaust port 6, and a block 50 provided on the upstream side of the air direction adjusting means 10 for suppressing the flow of air toward an inner wall 2a of the blow port body 2 into an air distribution region at the downstream side of the air direction adjusting means 10 when the air direction adjusting means 10 specifies an air distributing direction inclined to the axis of the blow port body 2. The block 50 has an irregular portion 52 at the side, and the irregular portion 52 suppresses the occurrence of a certain air stream when the air moving along the surface of the block 50 separates from the side of the block 50, thus reducing unusual noises such as whistling sounds.
