Gas lighter

A gas lighter comprising a lighter body in which fuel gas is stored, a fuel supply mechanism which supplies the fuel gas in the lighter body to a nozzle by way of a valve mechanism, an actuator lever which is provided with a nozzle engagement portion to be engaged with the nozzle to cause the nozzle to eject the fuel gas in response to depression of a depressing portion, an ignition means comprising a file wheel provided with a side wheel on each side thereof and a flint pressed against the file wheel to generate a spark upon rotation of the file wheel and to ignite the fuel gas generated through the nozzle, and a cap mounted on an upper portion of the lighter body, wherein the improvement comprises that

• the side wheel and the file wheel are supported on a support column so that their axes of rotation are rotatable and movable in a direction in which the flint is retracted, and an engagement projection is provided on the periphery of the side wheel so the that engagement projection on the periphery of the side wheel is engaged with an engagement portion provided on the cap to prevent rotation of the file wheel, thereby locking the lighter not to be ignited, and is disengaged from the engagement portion upon movement of the side wheel in the direction in which the flint is retracted, thereby allowing the side wheel to rotate and releasing lock of the lighter, wherein
• the side wheels are mounted on a rotary shaft which is elliptical in cross-section and is supported by a bearing hole provided in a support column which is provided on the lighter body to extend vertically and is provided with a slant surface in a lower portion thereof so that the rotary shaft of the side wheel is rotatable and movable in a direction in which the flint is retracted, and is moved upward upon rotation thereof.
