PROBLEM TO BE SOLVED: To make the assembling easier and to prevent the dislocation of a cap by forming chamfering along the peripheral of a recessed part so that a hook part formed on the cap of a lighter and the recessed part formed on a supporting column formed on the upper edge of the lighter can be engaged and fixed. SOLUTION: On the under part of both edges of the side plate of a cap 7 of a lighter, a hook part 6 is formed. The hook part 6 comprises elastic cut pieces 11 that are formed to protrude towards the inside of the cap 7 with trapezoidal shapes. The recessed part 15 that is engaged with the elastic cut pieces 11 of the hook part 6 is formed on a supporting column 16 that is erected on a middle case part 3. On a side of the peripheral of the recessed part 15, a chamfered part 17 that is slanted outward from the center part of the depth is formed. Therefore, the edges of the elastic cut pieces 11 of the hook part 6 touch the slanted surface of the chamfered part 17, the elastic cut pieces 11 slide to the inside of the recessed part being pressed consecutively and the hook part 6 and the recessed part 15 are engaged securely. |
