To provide a refuse separating dust box capable of storing refuse up to a refuse collecting day without an odor, while coping with an increase, when the refuse separating number increases at the present day.

An odor does not come out since the inside of the refuse separating dust box is not partitioned by a dust bucket called a pail but sorted by paper bags 15, 16, 17, 18 and 19 placed below after being completely dried in a paper bag 12 hooked on a side surface horizontal plate 3. There is no need to conventionally wash the pail by changing to a separate paper bag when the paper bag becomes dirty.
