<p><P>PROBLEM TO BE SOLVED: To provide an economical cartridge-type rifle toy gas gun having high hobby performance, and capable of reducing energy loss, improving gas jetting initial speed and jetting efficiency, improving targeting accuracy, reducing jetting of raw gas, improving gas efficiency (fuel cost) by stabilizing jetting of gas, accumulating much gas with compact and good appearance, and simplifying constitution, and easy to mass-produce. <P>SOLUTION: A gas accumulation chamber 5 is disposed at a lower part of a cartridge chamber, a gas tank unit C includes the gas accumulation chamber 5, a gas flow channel 6 formed at a rear side of the gas accumulation chamber 5 at an upper part of the gas accumulation chamber 5, and a valve mechanism, a flow channel 55 communicating the gas flow channel 6 with a rear end opening part of a cartridge F is formed on a tip part of a bolt body 50 of a bolt unit E, a gas in the gas accumulation chamber 5 reaches a bullet 90 set at a tip part of the cartridge F through the valve mechanism, the gas flow channel 6 and the gas flow channel 55, and the bullet 90 can be shot by gas jetting pressure. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
