PROBLEM TO BE SOLVED: To inexpensively change a size of a volume regulating chamber in an aerosol type volume regulating valve. SOLUTION: A valve main body 14 made of a metal is provided to a volume regulating valve 12. In the valve main body, a stem storing part 15 is formed which is cylindrical in its shape and which is projected downward in the center of the valve body. The lower end of a stem 24 is stored in the stem storing part. Further, the stem storing part has a center hole 19 at its bottom, and its lower part is pushed into a volume regulating tank 20 under pressure. With this arrangement, the volume regulating tank is mounted in the valve main body, whereby a volume regulating chamber 22 is divided. Thus, contents in the volume regulating chamber are injected through the inside of the stem for each injection operation. When an injection quantity for each injection operation is desired to be varied, the volume regulating tank 20 is replaced with ones having other shapes to thereby vary a size of the volume regulating chamber.
