To provide a pulley apparatus in a system that uses a traveling chain line to tow and transport logged trees over the ground surface and a chain collecting system using the same, in which a part of the traveling chain line is kept above the ground and kept in the air and/or deflected laterally, and which can allow both a suitable length of a base-attaching cable holding the logged trees and a hook tying the base-attaching cable to any position on the chain line to pass both through without getting entangled in the chain line.SOLUTION: There is provided a pulley apparatus with a pair of cantilevered disk-shaped rotating body, with opposing surfaces facing each other with a predetermined gap. One of the disk-shaped rotating bodies has a protrusion extending beyond the gap toward the other disk-shaped rotating body in a form in which a part of the outer peripheral surface thereof extends. The other disk-shaped rotating body has a recess for accommodating the protrusion with a predetermined gap.SELECTED DRAWING: Figure 3
