The first pin () comes into rolling and sliding contact with the second pin () at the contact portion (D). The first pin () includes a pair of end faces () opposing each other in the chain width direction (W), and a contact region () that comes into contact with the corresponding sheave surfaces of the pulley is formed in each end face (). The contact region () includes the center point of contact (M). The first pin () includes a first type pin () and a second type pin ().
