Zusammenfassung:PROBLEM TO BE SOLVED: To easily and firmly attach a fuel blocking valve to a support body in a fuel tank unit. SOLUTION: The fuel tank unit includes the fuel blocking valve 20 fixed to the support body 10. The support body 10 and a casing 22 of the fuel blocking valve 20 are formed of first and second resin materials having different fuel swelling rates, respectively. The fuel blocking valve 20 is fixed to the support body 10 through a fixing mechanism. In the fixing mechanism, first and second fixing engagement portions 28e and 28f that are claws formed in the casing 22 of the fuel blocking valve 20 are engaged into a first support side engaging portion 15e and a second support side engaging portion 15f of the support body 10 by first and second engagement amounts that are engagement allowances, respectively. These engagement portions are set so that the first claw engagement mount is larger than the second claw engagement amount before the support body 10 and a bottom lid 28 are subject to fuel swelling, and the second claw engagement amount is larger than the first claw engagement amount after the fuel swelling.
