Abstract: A fuel tank structure has a plurality of cylindrical tank main bodies (4), a piping (36) arranged to communicate the end portions of the tank main bodies 4 from one another and a block-shaped connector portion (35) provided at the outside of the end portion of the tank main body (4). The piping (36) couples the corresponding connector portions (35) to each other and is entirely disposed to the tank main body side with respect to an end surface of the connector portion (35), which is on the opposite side to the tank main body (4) with respect to the connector portion.

Abstract: A fuel vapor discharge limiting device for limiting communication between a fuel tank and a fuel vapor discharge pipe for discharging a fuel vapor in the fuel tank. The fuel vapor discharge limiting device includes a first float valve for cutting off the communication between the fuel tank and the fuel vapor discharge pipe when a liquid level in the fuel tank rises near a predetermined full level; a relief valve for allowing the communication between the fuel tank and the fuel vapor discharge pipe when an internal pressure in the fuel tank becomes not less than a predetermined value; and a second float valve for blocking the communication allowed by the relief valve when the liquid level in the fuel tank abnormally rises over the predetermined full level. Accordingly, oversupply of liquid fuel to the fuel tank can be prevented, and the internal pressure in the fuel tank can be maintained always within a predetermined permissible range.
