ABSTRACT:
A driving piston4is provided slidably up and down in a driving cylinder3arranged in a tool body1. By moving a movable sleeve10provided at the upper portion of the driving cylinder3up and down, the movable sleeve10is brought into contact with and separated from the driving cylinder3and a cylinder head8provided above the driving cylinder3, whereby a combustion chamber can be opened and closed. Mixture gas obtained by stirring and mixing combustible gas and air together in the combustion chamber by a fan16is ignited by an ignition plug15disposed at the cylinder head8and explosively combusted. By this high-pressure combustion gas, the driving piston4is impulsively driven, and a driver5coupled to the lower surface side of the driving piston drives nails. Between an exposed base portion of a center electrode of the ignition plug15which is exposed to the outside facedown and a leading end of the center electrode, there is provided a stagnation part25which stagnates temporarily a residue remaining after the combustion of the mixture gas.
