DEVICE FOR CONTROLLING AIR FLOW AROUND VEHICLE SIDE MIRROR

PROBLEM TO BE SOLVED: To deflect an air flow to a side mirror along a vehicle body outer surface without collision with the side mirror while preventing an increase in air resistance.SOLUTION: On the outside face of a head lamp lens 11, an air flow splitting protrusion 11a is provided which extends in a direction of an air flow for splitting the air flowing toward a door mirror 9 into an inside air flow α and an outside air flow β that may not be mixed with each other into a turbulent flow. The inside face of the protrusion 11a is formed as an internally curved air flow inward guiding vertical wall 11b which is finally directed to the inside of the door mirror 9 while extending inward in the cross direction of a vehicle as extending downstream in the direction of the air flow. The vertical wall 11b extends so that the rear end in the direction of the air flow extends to the side face of the vehicle body, for deflecting the inside air flow α in a laminar-flow state to the inside of the door mirror 9 in the cross direction of the vehicle. The outside face of the protrusion 11a is formed as an outside air flow downward guiding face 11c which is directed to the lower side of the door mirror 9 while extending downward as extending downstream in the direction of the air flow.
