    • PROBLEM TO BE SOLVED: To provide a manufacturing method for a pin for a power transmission chain, which enables machining of pin end faces in different shapes for offset random without changing a carrier, and reduces labor and time required for grinding.
      SOLUTION: A pin of a small offset wherein a contact position with a pulley of a pin end face is near the pin center, and a pin with a large offset wherein a contact position with the pulley of a pin end face is far from the pin center are ground without changing the carrier or a shape of a grinding wheel. When grinding the pin P2 with the large offset, the distance between the carrier 32 and the grinding wheel 33 is reduced for just a difference amount Δyd of offsets in comparison with when grinding the pin with the small offset.

SOLUTION: A first pin 3 in a power transmission chain has an end surface 17 engaged with a sheave face in a pulley.

      SOLUTION: Pins 3A, 3B are supported by a pin holding part 33 of a carrier 31 such that grinding support angles between centerlines T3 of the pins 3A, 3B and a reference line M of the carrier 31 become predetermined values. A peripheral groove 32a is provided on a disk-shaped grind stone 32, and both side walls of the peripheral groove 32a serve as grinding faces 32b. While the carrier 31 holding the pins 3A, 3B is rotated with respect to the grind stone 32 rotated around a center shaft 32z, the pins 3A, 3B are passed between the rotated grinding faces 32b to perform grinding. During the grinding, since the respective grinding support angles with respect to the pins 3A, 3B are set to have different values (0 and ν), respective end faces 3A1, 3B1 are formed to have convex surfaces of which attack angles with respect to a sheave face vary with each other. Then, the pins 3A, 3B are randomly arranged in the longitudinal direction of the power transmission chain.
