Title:
Body rear structure
Document Type and Number:
Japanese Patent JP5983384
Kind Code:
B2
Abstract:
In a vehicle (10) to which a vehicle-body rear structure (S) is applied, a first opening (40) is formed in a vertical wall portion (36), and a second opening (54) is formed in an underfloor (28). Accordingly, an airflow (A) partially flows into the first opening (40) and hits a rear face of an inclined wall portion (46), so as to be discharged from the second opening (54) toward a vehicle rear side. In the meantime, the airflow (A) that cannot enter the first opening (40) flows toward the inclined wall portion (46) along the vertical wall portion (36) so that the airflow (A) is drawn to the airflow (A) flowing into the first opening (40). Accordingly, the airflow (A) that cannot enter the first opening (40) flows toward the vehicle rear side along the inclined wall portion (46). As a result, detachment of the airflow (A) from the inclined wall portion (46) is restrained, and the airflow (A) flows toward the vehicle rear side along the underfloor (28) of the vehicle. Hereby, it is possible to restrain a decrease in steering stability due to the air flowing from a side part of the vehicle (10) into the rear wheel house (12).
