EFFECTS OF THE INVENTION By using the aerosol sprayer of the present invention, it is possible to effectively spray even on a place such as the back side of a leaf where spraying is difficult. Further, in the aerosol sprayer of the present invention, since the tube vibrates during spraying, it is possible to spray in a wider range. Further, the aerosol sprayer of the present invention can reduce the temperature drop due to the heat of vaporization of the propellant gas.
