Abstract:
1. A gas combustion type striking tool comprising: a combustion chamber in which mixed gas obtained by mixing and stirring combustible gas and air is combusted; a striking piston which is accommodated inside a striking cylinder and is driven by the combusted gas; a driver which is coupled to a lower surface of the striking piston; a nose portion which slidably guides the driver to strike a fastener; a feed pawl which is engagable with coupled fasteners housed inside a magazine; a feed piston which is coupled with the feed pawl and reciprocates the feed pawl along a direction in which the fastener is fed toward the nose portion; a stopper which is disposed so as to protrude into and out of a moving path of the reciprocating movement of the feed pawl; and a stopper engaging member which is coupled to a side wall of the combustion chamber, extends downward from the striking cylinder, and moves in a vertical direction, wherein, when the stopper engaging member moves downward, the stopper engaging member engages with the stopper to retract the stopper from the moving path along which the feed pawl is reciprocated.
