Claims

[Scope of utility model registration request]

A double plate structure locally joined by spot welding etc. is installed on the longitudinal walls and transverse bulkheads of the hull between the vibration/noise source and the living room, or on the front and rear walls, side walls, inner walls, etc. of the superstructure. A vibration and noise reduction structure for the hull.
