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.
