To reduce the capacity of a canister while restraining the risk of fuel splashing during oil supply.SOLUTION: A sealed type fuel tank system 1 includes a tank 2 for storing fuel FL, an oil filler 61 as a fuel inlet to the tank 2, a lid 8 for opening and closing a storage unit 81 storing the oil filler 61, a canister 3 for adsorbing evaporated fuel FV generated in the tank 2, a sealing valve 5 disposed on a passage 4 connecting the tank 2 and the canister 3 and switching a communication state between the tank 2 and the canister 3 by being opened and closed, an operation unit 11 to be operated in order to open the lid 8, detection means 10A for detecting presence or absence of oil supply to the tank 2, and control means 10C for controlling opening/closing of the sealing valve 5 on the basis of information of the operation unit 11 and the detection means 10A. The control means 10C opens the sealing valve 5 when the operation unit 11 is operated, and closes the sealing valve 5 when the presence of the oil supply is detected by the detection means 10A.SELECTED DRAWING: Figure 1

    【課題】給油時の燃料飛散のリスクを抑制しつつキャニスタの小容量化を図る。【解決手段】密閉式燃料タンクシステム1は、燃料FLを貯留するタンク2と、タンク2への燃料投入口である給油口61と、給油口61を収容する収容部81を開閉するリッド8と、タンク2で発生する蒸発燃料FVを吸着するキャニスタ3と、タンク2及びキャニスタ3を接続する通路4上に介装されて、開閉することでタンク2及びキャニスタ3の間の連通状態を切り替える密閉弁5と、リッド8を開放するために操作される操作部11と、タンク2への給油の有無を検出する検出手段10Aと、操作部11及び検出手段10Aの情報に基づいて、密閉弁5の開閉を制御する制御手段10Cと、を備える。制御手段10Cは、操作部11が操作された場合に密閉弁5を開放し、検出手段10Aにより給油ありと検出された場合に密閉弁5を閉じる。【選択図】図1
