摘要：A pin (13) is relatively rotatably fitted into a pin hole (11a) formed in an outerlink plate (11o) of a chain. A plurality of helical grooves (13b) are formed on an outercircumferential surface of the pin (13). A pitch P between adjacent helical grooves in theaxial direction is equal to or less than a width in the axial direction of the pin hole (11a) of
the outer link plate. At least one helical groove is arranged to oppose an arbitrarygeneratrix on an inner circumferential surface of the pin hole. Also, when a radius of thepin is R and a relative rotation angle with the mating member is θ, a pitch P' in the
circumferential direction between adjacent helical grooves is Rθ or less. Thus, at least onehelical groove is arranged to always pass each position in a sliding range between the pin(13) and the pin hole (11a).
