Claims

[Scope of utility model registration request]

A fuel tank noise reduction structure in which a resin-made buttful plate having a constant thickness and a large number of open spaces is attached along an inner wall corner of the fuel tank, wherein the buttful plate is attached along an inner wall corner. The connecting piece of the mounting plate piece having the connecting piece is passed through the bent part of the buttful plate and fixed to the inner wall surface of the fuel tank, and the mounting plate piece is used to elastically deform the mounting plate piece along the A fuel tank noise reduction structure, characterized in that a front surface side of the buttful plate is supported against an inner wall corner portion of the fuel tank.
