PROBLEM TO BE SOLVED: To prevent the possibility of deforming the surface of a disk rotor main body made of a synthetic resin into an irregular rugged state by being in slide contact with metallic coins. SOLUTION: In the disk rotor R for coin conveyance in which plural coil receiving holes 50 are opened and formed as entirely radial symmetrically distributed type on the mutual intermediate zone between the central part and peripheral part of the disk rotor main body 40 made of synthetic resin, and plural backward curved blades 52 are projectingly provided backwards between the adjacent coin receiving holes 50, a reinforce ribs 55 for disk rotor consisting of plural metal members distributed in the entire radial symmetrically distributed type are planted between the adjacent coin receiving holes 50 while being fixed so as to expose the surface at almost the same height at the surface of the main body 40 of disk rotor.
