To provide a breather device of a fuel tank which can reduce a cost more than before, and can improve mountability to a vehicle.SOLUTION: Breather hoses 19, 20 are connected to ventilation ports 6, 7 at a two points which are separated from each other by a discharge in a fore-and-aft direction of an upper face of a fuel tank 1, the breather hose 19 is released to the atmosphere after being extended up to a rear-side prescribed position exceeding at least a fore-and-aft intermediate position, and the breather hose 20 is fixed to the upper face of the fuel tank 1 by being brought into a cabled state so as to be released to the atmosphere after being extended up to a front-side prescribed position exceeding at least the fore-and-aft intermediate position. Even if the fuel tank 1 is inclined to the fore-and-aft direction by a gradient of a road within a regulated range, and either of the ventilation port 6 or the ventilation port 7 in the fore-and-aft direction is sunk down under a liquid level of fuel, the breather hose 19 or the breather hose 20 connected to the ventilation port 6 or the ventilation port 7 which is sunk down under the liquid level is released to the atmosphere with a height at which the ventilation port is not sunk down under the liquid level.SELECTED DRAWING: Figure 1

    【課題】従来よりもコストの削減を図ることが可能で且つ車両への搭載性も改善することが可能な燃料タンクのブリーザ装置を提供する。【解決手段】燃料タンク1の上面の前後方向に距離を隔てた二箇所の通気口6,7にブリーザホース19,20を夫々接続し、ブリーザホース19を少なくとも前後方向中間位置を越えた後方の所定位置まで延ばしてから大気開放させ且つブリーザホース20を少なくとも前後方向中間位置を越えた前方の所定位置まで延ばしてから大気開放させるように配索した状態として燃料タンク1の上面に固定し、燃料タンク1が規定範囲の道路の勾配により前後方向に傾斜して前後何れかの通気口6又は7が燃料の液面下に没しても、該液面下に没した側の通気口6又は7に接続されたブリーザホース19又は20が前記液面下に没しない高さを経由して大気開放されるように構成する。【選択図】図1
