Description

  The present invention relates to a vehicle air-conditioning outlet structure that blows air into a vehicle compartment.

  In general, an instrument panel in a vehicle compartment is formed with an opening serving as an air outlet for air conditioning in the vehicle compartment. A duct is connected to the back side of the outlet. Air sucked in by outside air or inside air by a blower fan or the like flows through the duct and blows out into the vehicle compartment from the outlet. In addition, a wind direction adjusting device for adjusting the wind direction of the air is attached to the outlet part.

  The wind direction adjusting device includes a plurality of vertical fins arranged at predetermined intervals. By changing the direction of the vertical fins, the right and left wind directions of the air blown into the vehicle compartment are adjusted. However, the air that passes near the inner wall of the device, that is, the air that passes through the end of the outlet, is not easily affected by the vertical fins, and there is a possibility that the air will escape almost straight, and the vertical fins are effective. May not be able to guide the air. For example, in the air outlet located near the window side, the air passing through the vicinity of the inner wall of the air outlet at the air outlet adjusts the wind direction to the window side by the air direction adjusting device. Without passing, you may go straight through. Due to the effect of air passing straight through, there is a possibility that air cannot flow toward the window side as intended by the operator.

  As a method for solving such a problem, for example, as disclosed in Patent Document 1, a structure that narrows an inner wall portion is known. In this structure, the air near the inner wall can be directed toward the center of the outlet.
