AIR BLOWING DEVICE

Provided is an air blowing device capable of keeping an air outlet invisible to the extent possible without impairing a function as the air blowing device. An air blowing device (10) includes: a tubular body (21) defining an airflow passage (21a) and an air outlet (21 b); a guide wall (31) for guiding an airflow having passed through the air outlet in an intended direction; and an on-off valve (32) forming a part of the guide wall, which is capable of opening or closing a concave portion (34) formed in the guide wall. The guide wall has a convex surface shape protruding in a direction intersecting with a forward direction of the air outlet, and is arranged so that a projection image, which is obtained by projecting the guide wall onto an imaginary plane including the air outlet, covers the entire air outlet. The on-off valve is configured to open or close the concave portion in accordance with the intended direction.
