To provide a vehicle fuel tank structure which can stably inhibit deformation of a fuel tank body 40 caused by an internal pressure rise.SOLUTION: A vehicle fuel tank structure includes: a hermetic type fuel tank body 40 which stores fuel for a vehicle; and a deformation inhibition member 50 which inhibits deformation of the fuel tank body 40 in a vertical direction. The fuel tank body 40 includes a first fixed part 45, a second fixed part 46, and a third fixed part 47 fastened to vehicle body side fixing parts 35, 36 provided at a battery case frame 32 of the vehicle 1. The deformation inhibition member 50 comprises: an annular contact part 51 which is brought into contact with an upper surface part 420 of the fuel tank body 40; and a pair of connection leg parts 52 which is joined to the annular contact part 51 and fastened to the vehicle body side fixing parts 35, 36 through the first fixed part 45 and the third fixed part 47 of the fuel tank body 40.SELECTED DRAWING: Figure 5
