PROBLEM TO BE SOLVED: To provide a vibratory part feeder capable of setting a change in a part supply position to a desired value or less, by restraining reduction in part supply capacity caused by unnecessary vibration from a frame. SOLUTION: This vibratory part feeder has a base provided with a part feeder body having a vibration source being 200 Hz or more in an oscillation frequency, the frame for holding the base, and a vibration restraining spring arranged between the base and the frame and restraining vibration in at least the vertical direction. Assuming a spring constant of the vibration restraining spring as K(N/m), an expression ; 1.0×10<SP>6</SP>≤K≤5.0×10<SP>6</SP>is satisfied. COPYRIGHT: (C)2008,JPO&INPIT
