する燃料タンク。[Claims for Utility Model Registration] A filler pipe for fuel supply is connected to the tank body, and the mouth of the filler pipe and an air chamber secured in the upper part of the tank body are communicated with each other through a ventilation pipe, An evaporative pipe with a check valve interposed therein is connected to the air chamber so that it can be vented to the atmosphere, and the evaporative fuel mixed with the internal air of the tank body, which is vented to the atmosphere from within the tank body through the evaporative pipe and the ventilation pipe, is removed. In a fuel tank provided with an activated carbon storage section for storing activated carbon to be adsorbed, the activated carbon storage section is connected to the evaporative pipe and the ventilation pipe at the upper part of the air chamber at a position above the fuel-filled liquid level. arranged,
and the activated carbon storage portion communicates with the engine intake system, and the filler pipe has a seal located closer to the tank body than the communication position of the ventilation pipe for blocking communication between the internal air of the tank body and the atmosphere through the filler pipe. means is provided, the tank body is provided with a liquid level detecting means for detecting a liquid level full of fuel, and the ventilation pipe is provided with a solenoid valve that closes the valve when the tank is full based on a signal from the liquid level detecting means. A fuel tank characterized by being provided.
