ABSTRACT:
Disclosed is a fuel gas supply adjuster which allows free adjustment of the flame length and enables stable flame length adjustment, for example in a gas lighter. In the fuel gas supply adjuster of the invention, a membrane filter which can provide a minimum necessary fuel retaining volume is used as the filter so as to prevent the fuel from being fed excessively at the initial ignition. Moreover, in order to incorporate the membrane filter in a fully sealed structure with a minimum necessary space being secured therein, one surface of the membrane filter is brought into close contact with that surface of an elastic member which has a conical recess, and the other surface thereof with the pressing face of a pressing member, while the other face of the elastic member with the fitting face of a base member, and the side face thereof with the side sealing face of the base member, respectively. Adjustment of the fuel gas supply is designed to be carried out by deforming the elastic member under compression with the pressing member.
