PROBLEM TO BE SOLVED: To automatically bleed air in a gas pipe even when a gas container and a metering injection valve are disposed apart from each other. SOLUTION: In this gas combustion driving tool, a gas container storage part 21 from which the gas container 22 filled with a fuel gas is detachable and the metering injection valve 24 for blowing, a predetermined quantity, the fuel gas discharged from the gas container 22 are connected to each other through the gas pipe 23, and a fastener is driven by the combustion pressure generated by igniting and burning the mixed gas of the combustion gas and the air blown from the metering injection valve 24. The gas combustion driving tool comprises a metering injection valve operating mechanism for bleeding the air in the gas pipe 23 by preliminarily operating the metering injection valve 24 which is installed by storably disposing the gas container 22 in the gas container storage part 21.
