To heighten the reliability to secure the practicality in a gas combustion type coil nailer.
As to nails n, this portable fastener driving tool includes: a body 1 provided with a combustion chamber; a head part 3 provided on the front thereof; and a magazine 4 removably disposed on the lower surface of the head part 3. A magazine 4 is loaded with a coil-like nail strip. The head part 3 is provided with a guide cylinder 35 allowing a rod 17 and the nail n to pass therethrough, and a feed motor 47. The nail strip N is fed to the guide cylinder 35 by a feed gear driven by the feed motor 47. The power is supplied from a battery to the feed motor 47. Since the drive of the rod 17 and the feed of the nail are performed separately by power, the nail can be surely fed without impairing the accuracy and certainty of driving the rod 17.
