ABSTRACT:
A combustion device in a lighter, such as a gas lighter, comprises a base portion, which is associated with a nozzle for jetting a fuel gas and is provided with a primary air hole for introducing primary air into the fuel gas having been jetted from the nozzle, and a combustion cylinder, in which the fuel gas containing the primary air mixed in is burned. The combustion cylinder has a multiple pipe structure comprising a combustion inner pipe, in which the fuel gas containing the primary air mixed in flows, and a combustion outer pipe, which is located around the outer periphery of the combustion inner pipe and at a predetermined spacing from the combustion inner pipe. The space, which is defined between the combustion inner pipe and the combustion outer pipe, is formed as a secondary air flow path, through which secondary air is supplied to a combustion flame.
