PROBLEM TO BE SOLVED: To completely clean an interior of a gun barrel by providing a guide wheel rotating along a rifle in the barrel on an outer periphery of a cleaner body having a rotary brush inserted into the barrel, and providing a launcher for reciprocating the body in a muzzle via a cable. SOLUTION: When a gun barrel 3 is cleaned, a cleaner body 4 is first fixed to a muzzle 5 by vertically splitting a launcher 6 into to two portions. A rotary brush is rotated via a cable 14, fed into the barrel 3, and cleanser is output. In this case, a guide wheel 12 of the body 4 is fed along a rifle groove 11 spirally formed on an inner surface of the barrel 3, and hence the body 4 is moved in a direction of a breech 13 while rotating. And, the brush scrapes out refuse in the groove 111 without moving against a direction of the groove 11. When the body 4 arrives at the breech 13, a feed roller 41 is reversed to scrape out the refuse or cleanser from the muzzle 5 out of the barrel 3 by a scraper 29. |
