Abstract
The present invention provides a fuel tank structure capable of securely suppressing deformation of a fuel tank by mutual contact of a pair of upper and lower interference sections at the time of deformation of tank by negative pressure. On a peak wall and a bottom wall of the fuel tank, an upper stand-off and a lower stand-off are formed face to face vertically with a certain interval therebetween. The lower stand-off is larger in diameter than the upper stand-off, and includes a general surface for contacting a projecting end of the upper stand-off during application of negative pressure, and an annular rib for preventing dropping of the projecting end. Therefore, at the time of application of negative pressure, deformation of the fuel tank can be securely suppressed.
