PURPOSE: To provide a storage hopper which can effectively vibrate an appropriate portion with slight driving force and has a structure excellent in durability.

CONSTITUTION: A sub hopper 2 is placed inside a hopper body 1 forming a gap G between an inner peripheral face of the hopper body 1 and an outer peripheral face of the sub hopper 2, an upper part of the sub hopper 2 is connected and fixed to an upper part of the hopper body 1, and also a driver 7 attached to the hopper body 1 for deforming a lower part of the sub hopper 2 is provided, so that the sub hopper 2 is deformed when the driver 7 is actuated, thereby allowing arching of powder flowing in the sub hopper 2 to be crushed.
