減するように作用する。(Function) In such a vehicle body structure, for example, when the vibration input is upward, this force is transmitted from one end of the coupling member to the upper wall and lower wall formed on the side sill. Each of the walls deforms upward, and as a result, the upper part of the side wall that connects these walls moves towards the inside of the car, and the lower part moves towards the outside of the car, causing the floor panel to bend and deform downward. . Conversely, when the vibration input is downward, the floor panel bends and deforms upward. That is, this vehicle body structure acts to reduce noise in the vehicle interior by bringing bending vibrations to the floor panel that are in phase opposite to the vibration input.
