Beschreibung
Zusammenfassung:	An link of a caterpillar which is allowed to maintain stabilized durability for a long period. The fixing structure has a link, and a pin inserted into a pin inserting bore formed in the link. A peripherally extending concave groove formed on the end portion of the pin and an opening periphery conjugate to forms an annular space. In order to limit relative escaping motion of the pin in the off-opening side (toward receding direction), a escape limiting ring is fitted into the annular space. The hardness of the bottom surface of the peripherally extending concave groove is lowered than the surface hardness of a link engaging portion of the pin.
