The present gas internal combustion type nailing machine is provided with: a striking cylinder (5) for slidably accommodating a striking piston (6) therein; a combustion chamber (11) formed in an upper side and capable of being opened and closed; a compressor (25) for supercharging compressed air into the combustion chamber; a fuel supply device (19) for supplying a fuel gas into the combustion chamber; and a safety device for preventing the nailing machine from being driven for ignition when the supercharge pressure of the compressed air exceeds a set pressure value wherein the safety device is configured to prevent a switch (S) from igniting a mixed gas in the combustion chamber from being turned ON, by a control of an electric circuit (12,35) of an ignition control device based on a detect signal from a pressure sensor (47) for detecting a pressure in the combustion chamber which exceeds the set pressure value.
