PROBLEM TO BE SOLVED: To provide a swing sorting device which can be eccentrically driven and can simply be processed. SOLUTION: An eccentrically driving mechanism 31 comprises a bracket 19 attached to a shaking sieve case 21, an eccentric cam 17 attached to a linear driving shaft 26 in an eccentric state, and a rolling bearing 23 disposed between the bracket 19 and the eccentric cam 17. A guide surface for guiding the rolling balls of the rolling bearing 23 is disposed on the outer peripheral surface of the eccentric cam 17 to also use the eccentric cam 17 as an inner race of the rolling bearing 23.
