| description | PROBLEM TO BE SOLVED: To provide a barrel for an air gun improving hit accuracy by eliminating adverse effect such as an shape error or the like of a bullet as much as possible. SOLUTION: A structure of holding the bullet 3 while limiting a contact position is formed by providing a contact part 6 and devising the shape or the like of an elastic friction protrusion 2. The structure is formed to hold the bullet 3 at the center of the barrel. Further, the structure has a guide 7 in the barrel, and muzzle part shape which prevents oscillation of the bullet when shot out. With these countermeasures, the rotary motion of the bullet at a point of time when shot out is constant compared with the conventional one to improve hit accuracy. COPYRIGHT: (C)2008,JPO&INPIT |
