Abstract
A magazine for an air gun of this invention can be freely attached to and detached from an air gun body using a magazine body, and has a plurality of pellet holders capable of being loaded with one pellet at a time. The plurality of pellet holders move orbitally about a pellet holder path and the pellets can be fed one at a time from the pellet holders towards a rotary sub chamber positioned below. With the air gun of this invention, the direction of the rotary sub chamber can be changed by shifting a rotary sub chamber positioned below the magazine, a trans link and a bolt forwards and backwards, so that the direction of single pellets dropping from the magazine can be changed by ninety degrees for feeding into the barrel. The magazine conveyor link is also interlocked so as to move to the front and rear in unison with movement to the front and rear of the trans link.
