To provide a new aerodynamic sound reduction structure which enables reduction of aerodynamic sound occurring in a storage space provided at a bottom part of a vehicle body of a railway vehicle to store a truck.SOLUTION: An aerodynamic sound reduction structure reduces aerodynamic sound occurring in a storage space S which is provided at a bottom part of a vehicle body 20 of a railway vehicle 1 to store a truck 10. The truck 10 has: side beams 14; and side protruding members 30 each of which protrudes to the storage space S at the outer side of the side beam 14 in a plan view.SELECTED DRAWING: Figure 2
