Abstract
A fuel cap where a valve body held to a valve support plate for performing pressure adjustment is arranged in a cap body installed to a filler neck of a fuel tank, and the part number can be decreased. The valve body has an outer circumferential lip element which is projected from an outer circumferential edge and pressed against an annular projection projecting inward in a fluid flow path of the cap body, and an inner circumferential lip element which is projected from an inner circumferential edge in reverse direction to the outer circumferential lip element. The valve support plate supports the valve body from rear side of the outer circumferential lip element, and has a seal member against which the inner circumferential lip element is pressed from the support position to inner circumferential side. Biasing means for pressing the outer circumferential lip element of the valve body is connected to the valve support plate. At the outside of the seal member in the valve body or the valve support plate, a communication hole which performs communication of the atmosphere side with the fluid flow path of the cap body is formed when the inner lip element is separated from the seal member.
