A fuel tank structure for a vehicle using gaseous fuel, has a plurality of cylindrical tank main bodies communicating from one another. The plurality of cylindrical tank main bodies are disposed at a fuel tank mount portion in a state of being adjoined from one another.

Fuel tank structure

In an antistatic structure of a fuel pipe, the fuel pipe to be charged in contact with a fuel, and a brake pipe connected electrically to a vehicle body are coupled to each other through a conductive clamp in at least one portion.

Antistatic structure of fuel pipe

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. Furthermore, discharge of the liquid fuel to the fuel vapor discharge pipe can be prevented.
