PROBLEM TO BE SOLVED: To provide a cracker wherein an injected article after jumping out into the air is prevented from scattering using a coupling string, and simultaneously when the injected article jumps from a cylinder, the coupling string is suppressed in its being left behind in the cylinder or entangled to extend a scattering distance of the injected article. SOLUTION: An injected article 6 is coupled with the side of a cylinder 1 through a coupling string 7 without a trend of twisting. For the coupling string 7 a cotton like structure comprising a resin made string and a band shaped structure such as a resin made film.
