動二輪車用燃料コツク。 In a fuel tank for motorcycles that uses intake pipe negative pressure to allow fuel to be supplied when the internal combustion engine is operating, and to cut off the fuel supply when the engine is stopped, air intake is carried out by a diaphragm fixed to the tank body that opens and closes the fuel supply passage. A diaphragm chamber on which negative pressure acts is provided, and a relief passage is provided that weakens the intake pipe negative pressure in the diaphragm chamber when the internal combustion engine is stopped, and the relief passage is closed when the internal combustion engine is in operation, and the relief passage is closed when the internal combustion engine is stopped. A fuel tank for a motorcycle, characterized by being provided with a control mechanism for releasing the fuel.
