A gas combustion type coil nailer is provided with (a) a main body (1) which is provided with combustion chamber; (b) a head part (3) which is disposed on the front surface of this; and (c) a magazine4which is disposed on the bottom surface of the head part (3) so that it can be attached and detached easily. A coil shaped nail connecting body is loaded onto the magazine (4). The head part (3) is provided with (d) a guide tube (35) through which the rod (17) and the nail n pass; and (e) with a feed motor (47). The nail connecting body N is fed to the guide tube (35) by a feed gear which is driven by the feed motor (47). Power is supplied to the feed motor (47) from a battery. The rod (17) is driven and the nail is fed by separate motive forces so that the nail can be fed reliably without adversely affecting the accuracy and reliability of the driving capacity of the rod (17).
