To provide a fuel tank fitting structure which can prevent breakage of a fuel tank without increasing the number of components.SOLUTION: A fuel tank fitting structure 1 comprises a cross member 3 which is provided between a rear part of a front floor panel 4f and a front part of a rear floor panel 4r of a vehicle, and a fuel tank 2 which is fitted to a rear end face part 3r side of the cross member 3. The fuel tank 2 comprises a front end face part 2f along a vehicle width direction, and two inclined plane parts 2c, 2c which are connected to both ends of the front end face part 2f and cross in the vehicle width direction in a top view. The cross member 3 comprises a pair of fitting parts 33, 33 which projects rearward in a top view. Each fitting part 33, 33 includes opposite face parts 33r, 33r which are so located as to be opposite to each inclined plane part 2c, 2c. At the time of back collision, three parts comprising the front end face part 2f and both inclined plane parts 2c, 2c contact three faces of the rear end face part 3r and the fitting parts 33, 33, thereby dispersing a force acting on the fuel tank 2 and preventing breakage of the fuel tank 2.SELECTED DRAWING: Figure 1

    【課題】部品点数を増加せず、燃料タンクの割れを防止できる燃料タンクの取付構造を提供する。【解決手段】燃料タンクの取付構造1は、車両のフロントフロアパネル4fの後部とリヤフロアパネル4rの前部との間に設けられるクロスメンバ3と、クロスメンバ3の後端面部3r側に取り付けられる燃料タンク2とを備える。燃料タンク2は、上面視で、車幅方向に沿った前端面部2fと、前端面部2fの両端に繋がり、車幅方向に交差する二つの傾斜面部2c,2cとを備える。クロスメンバ3は、上面視で、後方に突出する一対の取付部33,33を備える。各取付部33,33は、各傾斜面部2c,2cに対向配置される対向面部33r,33rを含む。後突時、前端面部2fと両傾斜面部2c,2cとの三カ所は後端面部3rと取付部33,33との三面に当接することで、燃料タンク2に作用する力を分散し、燃料タンク2の割れを防止する。【選択図】図1
