PROBLEM TO BE SOLVED: To provide a vehicle body structure reducing aerodynamic sound generated from a moving vehicle having a cavity or a cavity along with an inclusion on the surface of the vehicle such as a vehicle connecting part or an under-floor truck. SOLUTION: The aerodynamic sound generated from the impingement is reduced by providing a nozzle for air jet flow at the front side of the vehicle advancing direction of the cavity, brushing aside main flow entering the cavity along the vehicle wall surface by the jet flow, and preventing main flow from directly impinging to the cavity and the inclusion of the cavity.
