Abstract: When a chain is wound around a pulley, a pin-pulley contact point as a contact point of a pin of the chain with the pulley slides and moves on a conical surface of the pulley. A contact point slip distance, namely the distance by which the pin-pulley contact point moves on the conical surface at this time, is associated with an offset. The offset is the distance between a pin-pin contact point, which is a contact point between the pins at the time the chain is in a linear state, and the pin-pulley contact point in a y-axis direction. Offsets that minimize the contact point slip distance at the maximum running radius and the minimum running radius of the chain are obtained, and the offset is set between these values. The pin-pulley contact point is set close to the pin-pin contact point of the chain in the linear state.
