Title:
REAR SWIRL FLOW CONTROL AIR RESISTANCE REDUCTION DEVICE
Document Type and Number:
Japanese Patent JP2020055507
Kind Code:
A
Abstract:
To solve such problems that a box-shape vehicle such as a truck has large air resistance at traveling which adversely affects fuel economy and a loading space dimension is reduced in a vehicle of which whole length is regulated by a large roof spoiler.SOLUTION: A rear swirl flow control air resistance reduction device includes: a plurality of opening parts in a vehicle rear face part; and an air chamber for connecting them to each other, thereby reducing a difference in air pressure at a surface of a vehicle body rear part; thus a turbulent flow in the vehicle body rear part is reduced.SELECTED DRAWING: Figure 1
