PURPOSE:To enhance the transporting speed of an electromagnetically vibrated parts feeder to be used for an automatic assembly machine etc. by making a supporting lief spring for a balancer system with a thickness greater than that of a lief spring to support the ball system. CONSTITUTION:A lief spring 5 to support a balancer is given a thickness greater than that of a lief spring 6 to support the ball system, and thereby the vibration amplitude of the balancer system is made smaller than that of the ball system. Here, the spring constant of the balancer system spring 5 should increase, but change in the natural frequency is prevented by changing the material for the balancer or making adjustment with an additional weight 11. This provides possibility of increasing the attractive/repulsive force of electric magnet through boosting of the impression voltage without changing the gap between the magnet and armature to be attracted, which should lead to increase of the transporting speed.
