COMBUSTION TYPE DRIVING MACHINE

PROBLEM TO BE SOLVED: To provide a combustion type driving machine capable of certainly feeding a fastener interlocking with movement of a push lever.SOLUTION: An arm 44 is relatively moved to a left downward side in a first through-hole 41a relative to the push lever 41 accompanying with ascending of the push lever 41. The arm 44 is guided into the first through-hole 41a by a guide member 46 and is moved from a first restriction wall 41F toward a second restriction wall 41G while engaged with a first guide part 41D. Thus, by moving a feeder 43 from an initial position to a feed position, a claw part 43B presses a leading screw 1A to feed it to an injection port.
