The frequency which allows continuous injection of a fixed amount in the use of one cycle is controlled so as to prevent the use of aerosol contents in excess of a control amount. Further, it is made possible to inject all amount to the outside each time by a fixed-amount injection valve, thereby simplifying the mechanism and preventing damage to the distributing device due to the influence of outside air temperature. A lower receiving blade 31 is disposed in an outer sleeve 14 fixed to the upper end of an aerosol container 1 through vertical insertion intervals 32, 27 and is inserted in the lower insertion interval 32 by positional shift, thereby a fitting piece 22 which allows pressing by a stem 7 is projectingly formed on a pushing body. Further, an upper receiving blade 36 which allows the pushing body 15 to move in the same direction as the direction of said positional shift is formed in the inner surface of an upper sleeve 24 through the upper insertion interval 37. After the positional shifting of the pushing body 15 accompanying a plurality of times of pressing, movement into the lower insertion interval 32 is made impossible, thereby making fixed-amount injection of aerosol contents impossible.
