Abstract: In the register 1 of the embodiment, in case that all of the front side fins 41 are rotated to the upward direction, air flowing toward the air outlet 21 (air flow direction X) of the bezel 2 in the air flow path 3A of the retainer 3 is blown out from the air outlet 21 of the bezel 2 and the blowout direction is changed to Y1. At that time, air flow separating from the concave surface existing on the lower surface of the front side fin 41 approaches to air flow along the concave surface existing on the upper surface of the front side fin 41 positioned at a lower position than that of the above front side fin 41, and separates from the fixed fin 22. Thereby, air with superior directivity to the upper direction can be obtained.

Abstract: A register includes: an air outlet; a front movable louver disposed inward of the air outlet, the front movable louver turning vertically; and a bulging curved ledge portion disposed below an area in front of the air outlet. The ledge portion includes a curved surface that curves downward ahead, and a groove or a ridge for disturbing a flow of air along the curved surface is provided in parallel with a longitudinal direction of the front movable louver, in the curved surface.

Abstract: An air blowing device includes: a tubular body defining an airflow passage and an air outlet; a guide wall configured to guide an airflow having passed through the air outlet in an intended direction; and a movable projecting portion, which is capable of projecting from an inside of the guide wall to an outside of the guide wall. The guide wall has a convex surface shape projecting in a direction intersecting a forward direction of the air outlet, and is arranged so that a projection image, which is obtained by projecting the guide wall onto a virtual plane including the air outlet, covers the entire air outlet. The movable projecting portion is capable of adjusting a projecting amount from the guide wall within a range of from zero to a predetermined maximum amount, and configured to adjust the projecting amount depending on the intended direction.

Abstract: An air blowing device capable of keeping an air outlet invisible to the extent possible without impairing a function as the air blowing device, including: a tubular body defining an airflow passage and an air outlet; a guide wall for guiding an airflow having passed through the air outlet in an intended direction; and an on-off valve forming a part of the guide wall, which is capable of opening or closing a concave portion 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.

Abstract: 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 (21b); 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.
