ABSTRACT:
The end faces of a first pin contain bulging curved faces having an egg-like shape, when viewed along a chain width direction. Each bulging curved face includes a first end portion, a second end portion and a maximum width portion with respect to a chain advancing direction. With respect to perpendicular directions, the distance between the center of the maximum width portion and the first end portion is relatively large, whereas the distance between the center of the maximum width portion and the second end portion is relatively short. It is possible to enlarge the surface area of the bulging curved face.
