PURPOSE:To provide an electromagnetically vibrated parts feeder for a processing machine etc. with possibility of easy adjustment and maintenance and with max. vibration characteristics by installing lief springs between a base and a table by the use of bolts, wherein the springs are arranged at the periphery of the device concerned in such a way as oriented facing the center. CONSTITUTION:Lief springs 5, 6 are installed between a base 4 and an upper 2 and a lower 3 table by the use of bolts, wherein the springs are arranged at the periphery of the device concerned as oriented facing the center. This will facilitate both assembly and adjustment. The lief springs 5, 6 can be shifted from leftwise inclination to rightwise by moving the fixation position on the circumference of said base 4 one for another to the left on the attached illustration, which should provide a change in the rotating direction of parts in ball. Further, the angles of inclination of said lief springs 5, 6 can be easily changed, which should provide the max. vibration characteristics easily.
