By the way, cigarettes are cigarettes. It is said that it is preferable to ignite the cigarettes after warming them with a flame before igniting. Because the diameter is large compared to
If it is a small flame, it can only be heated partly and can only be ignited partly, and it is necessary to heat or ignite the cigar tobacco while rotating it in the circumferential direction. With the ignition flame of a gas lighter in shape, it took time and effort to achieve a favorable smoking state.

[0008] Such a problem arises as in the conventional gas lighter, in which the direction of the ignition flame is set to two directions, ie, a vertically upward direction and the horizontal direction.
Even with a gas ejection device capable of changing directions, the shape of the flame generated by this device cannot be solved because the shape of the flame is the same as in the prior art.

Therefore, an object of the present invention is to change the ignition flame to a normal shape similar to the conventional one and to a shape having a larger flame area than that of the normal shape. An object of the present invention is to provide a gas ejection device for a gas lighter that can also generate a suitable ignition flame.
