PROBLEM TO BE SOLVED: To provide a quantitative feeder, capable of quantitatively feeding parts in accordance with size of the parts. SOLUTION: In this quantitative feeder 1, parts 9 in a container 6 are attracted by an outer magnet 41 fixed to a disc 40 to be lifted by rotation of the disc 40. In a selection unit 20, an abutment part 22 of a selection plate 21 abuts on the parts 9 to regulate the attracting position, and the number of the parts 9 attracted by the outer magnet 41 is limited. In the selection unit 20, the position of a bracket 25 can be moved in accordance with the size of the parts 9, so that a gap between the abutment part 22 and the outer magnet 41 is adjustable. Even when the size of the parts 9 is varied, the attracting position in the outer magnet 41 to the parts 9 can be regulated to limit the number of parts 9 attracted in the outer magnet 41, thereby the parts 9 of any size can be quantitatively fed to the external part.
