PURPOSE: To make a flowing quantity uniform and stabilize a flow in the captioned gate in which a magnet and a piezoelectric oscillator are used and which is used for dividingly handling a medicine, etc. by providing the end part of the gate at an optional angle to the axis of a chute.

CONSTITUTION: The end part 12 of a gate 10 installed on the front half part in a chute 4 is inclined at a certain angle θ to the axis of the chute 4 in such a way that the tip end thereof comes to the right side or left side of the send- out direction of a powder/grain body A. This inclination angle θ is set at 10W60°. By this structure, at the start of flowing, the powder/again body A starts to flow in such a way that it threads from the tip end (a) and, then, flows being gradually spread over the whole width, finally flowing while being sided to the rear end (b) of the inclined part as the powder/grain body A comes near its end. By this structure, the flowing quantity can be made uniform while stabilizing a flow.
