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 a flow velocity adjusting mechanism (valve body) (22) capable of adjusting a flow velocity of the airflow passing through the air outlet.
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 flow velocity adjusting mechanism is configured to adjust the flow velocity in accordance with the intended direction.
