Claims

[Scope of utility model registration request]

Above the floors attached to car body reinforcement members such as side sills and cross members, anti-vibration floors are placed facing away from each other to prevent the transmission of vibrations from these floors. A floor plate structure for an automobile, characterized in that an elastic body is interposed between the vibration-proof floor and the spring constant of the elastic body can be changed mechanically by changing the contact area of the elastic body according to the load applied to the vibration-proof floor.
