[0013]

With this configuration, the other movable blades except for the movable blade at the end are made parallel to the flow direction of the air flowing through the flow path, and the movable blade at the end is operated by operating the rotating operation mechanism. The movable blade closes the side portion of the air outlet by turning the end portion thereof to the side surface portion of the case body, and blows the air F from the air outlet into the vehicle interior along the flow path. In addition, the terminal portions of the adjacent movable blades are overlapped with each other, or the adjacent movable blades excluding the movable blade at the end are rotated so that the terminal portions thereof overlap with each other, and the rotation is performed. By operating the dynamic operation mechanism to rotate the movable blade at the end and making the movable blade at the end parallel to the direction of flow of the air flowing through the flow path, deflection toward one side of the outlet is performed. A flow path can be formed, and the blowing air F is directed along the deflection flow path. For example, it is possible to blown out toward the side window.

Therefore, it is not necessary to separately form an air outlet structure serving as a side register and an air outlet structure serving as a side defroster, so that the number of parts is reduced, and the formation of a deflection flow path and the control of wind direction are movable. Since the control can be performed by the blades, a control system such as a switching valve in the blow-out duct is not required, the configuration is simplified, and the cost can be reduced.
