PURPOSE: To facilitate to change wick of each part, by engaging the vaporizer parts of a main wick and an auxiliary wick with the positions from which the vaporizer parts are detached to the upward direction of a suction part, in the wick of which main wick and auxiliary wick, being burnt at the ignition time only, are monolithically provided to a wick body, separated by a separator from each other.
CONSTITUTION: A wick is composed of a main wick 1 and an auxiliary wick 2, and the main wick 1 is composed of a vaporizer part 3, made of ceramic fiber, and suction parts 4 and 5, made of knitted fabric, connected to the lower part of a vaporizer part 3. On the other hand, the auxiliary part 2 is also composed of a vaporizer part 6 and a suction part 7, fitted to the inside of a main wick 1, by the intermediary of alternately detachable sseparators 8W10, made of a substance which do not allow fuel to pass through. In this case, a plurality of projections 12 are provided to the surface of an outer periphery of a separator 8, and these projections 12 can be engaged with long holes 14 which are perforated to the circumferential direction, by the intermediary of guides 13 which are provided to the inside of a separator 9 to the axial direction. Besides, the suction parts 4 and 5 can be detached as far as the distance (a), by engaging the projections 12 with engaging parts 18, which are downwardly extended to be continued to the long holes 14.
