As the propellant 19 is ignited, the body 13 is separated from the shell 11 and travels a predetermined distance. The delayed fuse 21 connected to the propellant 19 is ignited while passing through one side of the body 13 while the body 13 is flying a predetermined distance.

The delayed fuse line 21 is burnt for a predetermined time to ignite the complexing agent 23 connected to the delayed fuse line 21 on the inside of the body 13. The flame emitted from the complexing agent 23 passes through the plurality of projections 25, 27 and 29 and the flame passage opening 43 along the inner cylinder 35 formed in the body 13, Lt; / RTI > The reversing agent 33 transmits a reverse thrust force to the plurality of projections 25, 27, 29 so as to fly in a direction opposite to the flying direction of the body 13. The plurality of magazines 25, 27 and 29 are separated from the body 13 by the inversion agent 33, and can discharge a tear gas, a smoke film, and an infrared ray blocking agent to a wide range by one shot.
