PROBLEM TO BE SOLVED: To enable a spring to be easily housed in an inner cap to improve the assembly work efficiency in a fuel cap for a fuel tank including: an inner cap; an outer cap coupled to the inner cap; a fastening member which is held by the inner cap while protruding a pair of engagement parts from an outer periphery of the inner cap to a side; and a spring provided between the fastening member and an inner end part of the inner cap.SOLUTION: An inner cap 10A is formed by coupling a first inner cap half body 15A which is coupled to an outer cap 11 to a second inner cap half body 16 which sandwiches the first inner cap half body 15A with the outer cap 11. In a fuel cap for a fuel tank, a spring 13 is provided between a fastening member 12, which penetrates through the first inner cap half body 15A, and an end part of the second inner cap half body 16 which is opposite to the outer cap 11.SELECTED DRAWING: Figure 1 |
