Claims

[Claims for Utility Model Registration] (1) A noise-absorbing structure for a fuel tank in which a resin buttful plate having a certain thickness and having a large number of open-surface voids is attached along the inner wall of the fuel tank, fixing the legs of a mounting plate piece having a plurality of legs to an inner wall surface of the fuel tank;
A fuel tank noise reduction structure, characterized in that the mounting plate piece supports a part of the buff-full plate so as to straddle the inner wall surface of the fuel tank. (2) A sound-absorbing structure for a fuel tank in which the rear surface of a buff-full plate, which has a plurality of resin needles protruding from the surface of a resin base material, is attached to the inner wall surface of the fuel tank, wherein the buff-full plate A through hole is provided in the mounting plate, and the feet of a mounting plate piece having a plurality of legs are fixed to the inner wall surface of the fuel tank through the through holes from the surface of the buttful plate, and the mounting plate piece is attached to the wall surface inside the fuel tank. A fuel tank noise reduction structure, characterized in that the fuel tank is supported so as to straddle a part of the buttful plate. (3) A sound-absorbing structure for a fuel tank in which a resin mesh-like buttful plate having a certain thickness and a large number of open-surface gaps is attached along the inner wall surface of the fuel tank, and the mounting has multiple legs. The foot of the plate piece is fixed to the inner wall surface of the fuel tank through a gap from the surface of the buttful plate, so that the mounting plate piece straddles a part of the buttful plate with respect to the inner wall surface of the fuel tank. A fuel tank noise-muffling structure characterized by support.
