PROBLEM TO BE SOLVED: To provide a workpiece sorting mechanism of simple structure for sorting cylindrical workpieces formed so as to be brought in contact with a flat surface at least in two points thereof at a different diameter when it is placed on the flat surface so as to be brought in contact with the peripheral surface thereof, and unnecessary to perform maintenance frequently. SOLUTION: In this workpiece sorting mechanism, when a cylindrical workpiece 20 is formed so as to be brought in contact with a flat surface at least in two points thereof at a different diameter when it is placed on the flat surface so as to be brought in contact in the peripheral surface thereof. The workpieces 20 are conveyed so that the axial direction thereof is arranged along the conveying direction on an upstream side workpiece path 11a, and sorted workpieces 20 are conveyed in a second posture in a downstream side workpiece path 12 positioned lower than the upstream side workpiece path 11a. An inclined path 13 inclined in the rolling direction of the workpieces 20 has a circular outer edge part 13g, and connects the upstream side and the down stream side workpiece paths 11a and 12 to each other. The outer edge part 13g is formed on a large-diameter contact point 21c side of the workpiece 20 in the inclined path 13. COPYRIGHT: (C)2008,JPO&INPIT
