PURPOSE:To always obtain a prescribed vibration with a bowl feeder in which the inside and the outside bowls are vibrated by an electromagnet and an attractive iron piece, by constituting said electromagnet and attractive iron piece so as to be slided relatively and positioned freely. CONSTITUTION:The interval l between the electromagnet 20a and the attractive iron piece 20b of a vibrator 20 is adjusted by loosening a bolt 22. The head part of the bolt 22 shifts, guided in a concaved part 24, and the electromagnet 20a shifts in parallel with the attractive iron piece 20b, and thus the interval l can be adjusted uniform. With such a constitution, the interval l can be adjusted independently of an outer bowl 2, and a prescribed vibration can be always obtained. |
