。 A striking cylinder having an open upper end, a striking piston integrally provided with a nail driving driver slidably disposed within the striking cylinder, and a striking piston disposed opposite to the upper end of the striking cylinder to compress the inside of the striking cylinder. In a pneumatic nailing machine equipped with a main valve selectively connected to an air storage chamber and the atmosphere, the upper end of the percussion cylinder is provided with an elastic member connected to the outer peripheral surface of the percussion cylinder on the upper end surface of the percussion cylinder facing the main valve. A part of the sealing member is bulged inward of the striking cylinder, and the center of the upper end surface of the striking piston is provided with an annular sealing member having an outer diameter relative to the outer diameter of the striking piston. 1. A pneumatic nailing machine, characterized in that a convex portion having a reduced diameter is formed, and an annular groove that can be engaged with the bulging portion of the sealing member is formed on the outer peripheral surface of the convex portion.
