Abstract
A fuel cap of an internal combustion device includes a fuel cap body, a restraining element, a resilient element, and a positioning element. The slide block of the restraining element is normally resiliently pressed by the resilient element and therefore protrudes from the outer periphery of the main body portion of the fuel cap body. The fuel cap body can be inserted into a fuel tank when the engaging blocks of the fuel cap body are aligned with the gaps of the fuel tank, and the fuel cap body is subsequently secured when the slide block is engaged in a positioning notch formed on the outer projecting wall of the fuel tank. By pushing the pushing plate of the restraining element inward, the slide block is retracted into the slide groove of the fuel cap body to allow removal of the fuel cap body from the fuel tank opening.
