2. Description of the Related Art Conventionally, disposable lighters have been frequently used. However, the disposable lighter was difficult to adjust the amount of fuel squirt, and thus could not allow adjustment of the lighter flame length. Therefore, when the length of the flame of the lighter is too long, the user is confused because the length of the flame of the lighter cannot be shortened. As the name implies, a disposable lighter cannot be refilled once used, and a lighter using a rechargeable liquefied gas as fuel has been required. However, the mechanism for adjusting the amount of injected fuel is extremely complicated, cannot be manufactured at low cost, and is not always practical. Further, if the mechanism for adjusting the fuel injection amount is excessively simplified, the reliability of the function for adjusting the fuel injection amount is reduced, and practicality cannot be expected. Therefore, with the simplified mechanism for adjusting the amount of injected fuel, the sufficient performance cannot be expected in terms of practicality.

[0003]

SUMMARY OF THE INVENTION Accordingly, it is a first object of the present invention to provide a lighter which uses a liquefied gas which can be refilled with fuel by devising its internal structure even if it has the same appearance as a disposable lighter. Subject. The fuel injection valve of the lighter having the conventional fuel injection amount adjustment mechanism adjusts the fuel injection amount by the fuel injection amount adjustment mechanism. Although the mechanism has an extremely complicated structure, a second object of the present invention is to obtain a practical automatic lighter flame length adjusting device while avoiding a complicated structure.
