The present invention relates to a toy rocket capable of flying at a certain distance after launch of the toy rocket by detachable main wings to the toy rocket fuselage fired on the principle of simple air pressure.;To this end, the present invention comprises a tail 1b near the bottom of the rocket fuselage 11 to construct a toy rocket 10 which is air-launched by the blowing pressure of air when the PET bottle 7 is stepped on: a rocket fuselage (11) is characterized in that the technical configuration characterized in that the detachable means 20 of the main blade 22 is mounted in a predetermined manner so that the toy rocket 10 can fly in high air after being launched into the air. The detachable means 20 has a semi-cylindrical fitting portion 21 fitted to the outer circumference of the body 11, and a main blade 22 integrally formed with the fitting portion 21, and furthermore, on the body 11. It includes a double-sided tape 23 for preventing the separation of the fitting portion 21.;In addition, the main blade attachment and detachment means 20 may include a cylindrical insertion member 24 fitted to the outer circumference of the body 11 and having a plurality of through holes 24a, and in this case, a semi-cylindrical fitting portion 21. It is preferable that a plurality of protrusions 25 are formed on the inner side of the through hole 24a. In addition, the present invention is to form a plurality of projections (22a) on the main blade (22) to be directly fitted to the cylindrical insert member (24).
