PURPOSE:To prevent the entanglement of a lead wire by installing a vibration generating device on at least one of rectangular permanent magnets in the captioned device in which said two rectangular permanent magnets which are magnetized in a board thickness direction are opposite to each other at an interval to serve as the moving passage of magnetic shaft-like parts. CONSTITUTION:A magnet-feeder type magnet box 1 is fed with shaft-like parts 3 from a chute 2. The parts 3 are transferred along the moving passage in which two rectangular permanent magnet boards 4, 4 which are magnetized in a board thickness direction are placed at a defined interval with their mutu ally different poles being opposite to each other in such a way that the separat ing interval is gradually reduced in a taper form in the moving direction of the shaft-like parts 3. In this case, a vibration generating device 10 is installed on at least one of the rectangular permanent magnet boards 4. And, the interval on the opposite part of the rectangular permanent magnet boards 4 is varied at a short period by means of the vibration generating device 10, thereby, trans mitting minute vibrations caused by variation in magnetic field intensity to the shaft-like parts 3, to prevent the entanglement of a lead wire.
