<P>PROBLEM TO BE SOLVED: To provide a gas tap free of such an occurrence that the internal pressure of a valve accommodation part varies largely in association with a change in the outside air temperature. Ž<P>SOLUTION: The gas tap is structured so that an enclosing wall part 24 to enclose an opening of the valve accommodation part is formed at the top face of the gas tap body 2, an insertion hole 42 is formed in the undersurface of a handle for admitting insertion of the enclosing wall part 24 with possibility of relative rotation, and that the area between the peripheral surface of the enclosing wall part 24 and the inside surface of the insertion hole 42 is sealed with a seal member 9, wherein the handle is furnished with an air passage 10 to release the valve accommodation part to the outside and a first 11 and a second annular space 12 are formed midway through the air passage 10, and between these annular spaces 11 and 12, an annular gap 13 having a capillary phenomenon larger than them but narrower is formed.
