A subdivided fixed amount distributing apparatus for aerosol containers is provided in which aerosol contents exceeding a specified amount is prevented from being used in one cycle by keeping constant in total number of injection times at all times. A structure is simplified by making it possible to eject total amount to the outside every one time by means of a fixed amount injection valve, so that damage to the distributing apparatus due to outside air temperature is prevented and movement of the distributing apparatus is made smooth when it is pushed and released. The subdivided fixed amount distributing apparatus includes a lower sleeve 18 secured to an upper end of an aerosol container 1, a nozzle body 15 formed with a nozzle 16 communicating with a stem 4, a rotating body 23 disposed in a rotatable manner with respect to the nozzle body 15 and the lower sleeve 18, an annular body 34 disposed at an upper side of the rotating body 23, a pushing body 45 pushing the stem 4, and an upper sleeve 37 secured to the lower sleeve 18 at a lower end thereof, in which pushing operation of the stem 4 enables a fixed amount injection of the aerosol contents and positional movement of a fitting piece 28 while pushing operation of the stem 4 and positional movement in the same direction of the fitting piece 28 are disabled by hitting the fitting piece 28 on an upper end surface of a lower projection 21 after positional movement by pushing operation of predetermined times.
