PROBLEM TO BE SOLVED: To provide a saddle type fuel tank 11A in which liquid fuel does not reach a canister through an exhaust passage just after full tank fueling.SOLUTION: A saddle type fuel tank 11A includes: a saddle type tank body 13; and a full tank regulation valve 15 which is communicatively connected to an exhaust passage 27 continuous to a canister and is provided in a saddle-shaped section 21. The full tank regulation valve 15 includes: a valve body 31; a float valve 33; a first suspension pipe 35 which is communicatively connected to the valve body 31 and has a first opening 35a at a suspension end; and a second suspension pipe 37 which is communicatively connected to the valve body 31 and has a second opening 37a at a suspension end. The first opening 35a of the first suspension pipe 35 is set to be located at a height corresponding to a full tank liquid level RA1_full related to a first chamber 17. The second opening 37a of the second suspension pipe 37 is set to be located on a lower side than a height corresponding to a full tank liquid level RA2_full related to a second chamber 19.SELECTED DRAWING: Figure 1

    【課題】満タン給油直後において液状の燃料が排気路を通してキャニスタに到達することのない鞍型燃料タンク11Aを提供する。【解決手段】鞍型燃料タンク11Aは、鞍型のタンク本体13と、キャニスタに連なる排気路27に連通接続され、鞍状部21に設けられる満タン規制バルブ15と、を備える。満タン規制バルブ15は、バルブ本体31と、フロート弁33と、バルブ本体31に連通接続され、垂下端に第1開口部35aを有する第1垂下配管35と、バルブ本体31に連通接続され、垂下端に第2開口部37aを有する第2垂下配管37と、を備える。第1垂下配管35の第1開口部35aは、第1室17に係る満タン液位RA1_fullに対応する高さに位置するように設定される。第2垂下配管37の第2開口部37aは、第2室19に係る満タン液位RA2_fullに対応する高さと比べて下方に位置するように設定される。【選択図】図1
