A storing tank, in which the storage space can be multiplied to a suitable extent, and the area occupied by it can be reduced. It has a lower tank member, an access gate, a pushing mechanism, an upper tank member and an outlet. Material put in the access gate falls onto the pushing mechanism to be pushed upwardly into the lower tank member. When the latter is full, the upper tank member is moved upwardly by the increasing material to increase the receiving space until the upper tank member is moved to the highest position. When the outlet is opened, the material can automatically fall down along a bevel guiding surface in the lower tank member and out of the outlet.
