To provide a protection structure of a fuel tank which can prevent an attachment protruding upward of a rear skeleton member from breaking down even when an assailant vehicle runs onto the rear skeleton member at rear end collision.SOLUTION: In a protection structure 30 of a fuel tank 20, the fuel tank 20 includes a tank body 21 and a valve 22 which is provided on an upper part of the tank body 21. The tank body 21 is disposed below a rear side member 11 of a vehicle body 10, with only a front end part of the tank body 21 being fixed to the vehicle body 10. The valve 22 protrudes upward from the rear side member 11 and is covered with a protector 31. The protector 31 is fixed to the tank body 21, and includes: a top surface part 31A which covers a portion above the valve 22; a pair of legs 31B which is disposed between the top surface part 31A and the tank body 21 and is longer than a length in a vehicle vertical direction of the valve 22; and an inclination part 31C which inclines from the top surface part 31A rear-downward.SELECTED DRAWING: Figure 1

    【課題】後突時に加害車両が後部骨格部材に乗り上げた場合でも後部骨格部材の上方に突出した付属品の破損を防ぐことができる燃料タンクの保護構造を提供する。【解決手段】燃料タンク20の保護構造30であって、燃料タンク20は、タンク本体21と、タンク本体21の上部に設けられるバルブ22と、を有し、タンク本体21は、タンク本体21の前端部のみが車体10に固定され、車体10のリアサイドメンバ11よりも下方に配置され、バルブ22は、リアサイドメンバ11から上方に突出し、プロテクタ31によって覆われ、プロテクタ31は、バルブ22の上方を覆う天面部31Aと、天面部31Aとタンク本体21との間に配置され、バルブ22の車両上下方向の長さよりも長い一対の脚部31Bと、天面部31Aから後方かつ下方に向かって傾斜する傾斜部31Cと、を有し、タンク本体21に固定される。【選択図】図1
