PURPOSE: A chemicals-spraying gun for a fumigator using shape-maintaining bellows is provided to adjust and fix the direction of a spray hole to a desired direction, thereby preventing the unnecessary loss of chemicals due to scattering. CONSTITUTION: A chemicals-spraying gun for a fumigator using shape-maintaining bellows sprays chemicals which are formed of stored liquid stored in a chemicals container by using a strong wind from a ventilation fan. An air induction pipe(31) is flexibly connected to the gun by the air outlet of the ventilation fan and bellows(100). The shape-maintaining bellows changes and fixes the spray direction of spray gun to the end of an air induction pipe.
