A back face of each inner link plate of the chain is curved convexly. Heights from a pitch line connecting centers of pin holes of inner and guide link plates to the convex apex portion of the inner link plate and to an apex portion of the guide link plate are equalized. The convex apex portions are brought into contact with a guide face of the chain guide per every pitch and the ear apex portions are brought into contact with the chain guide per every pitch while being shifted by a half pitch from the convex apex portions.
