Abstract
A valve for preventing fuel leaking from a fuel tank includes a housing that has a passage that communicates with the outside. In the housing there is a float that is used to open and close the passage by being moved axially along the housing. The valve is provided with a device to guide the float to close the passage. The device includes a gap formed between the housing and the float that increases in size with increasing distance from the passage.
