いる。EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is not inferior to a two-fluid spray type spray gun using a compressor or a gas cylinder in the finished state of the coating surface, and it is inexpensive and easy to use as a power source. Since it is possible to use a battery that is available for use, it can be made into a compact shape with excellent mobility and can be supplied at a low price. Furthermore, since the spray pressure is low, the spray amount adjustment needle is operated. As a result, a narrow spray width of about 5 mm to 50 mm can be obtained, so it is possible to use conventional spray applicators such as writing letters on uneven surfaces that cannot be written with a brush or brush, illustration, and application to model work. It has many unique features.
