<p>PROBLEM TO BE SOLVED: To contrive to be hard to shorten the overall length of a gun body without shortening a moving distance of a piston or increasing a width in a direction perpendicular to a longitudinal direction of a cylinder and the piston, to fix a piston ring with an excess load, and to conduct remodelling for firing live ammunition. SOLUTION: In the air gun, a gas-blowing out hole 3 from which gas inside a cylinder 72 blows off is provided on a center line in a longitudinal direction of a bullet-pushing rod 23 or a cylinder 72 and connected with a connecting rod 34 penetrating through a nozzle body 38 fitted into the inside of the cylinder 72, a hand grip body 25, and a position 18 loaded by a piston spring 14 in a position in the center line of the longitudinal direction.</p> |
