Abstract:
A crawler belt and a master link for use in the crawler belt enable easy connection and disconnection of the crawler belt. The crawler belt has a track chain in which a plurality of regular links are pivotally connected at their ends, the master link for connecting the ends of the track chain to form the crawler belt into a loop, and track shoes attached to the regular links and the master link respectively. The crawler belt has a slit aperture which leads only to a pin insertion hole formed at the other end of the master link and is configured such that a clamping force, generated by tightening a master bolt that imparts a tightening force to the master link to narrow the slit aperture, is allowed to work on only the regular pin inserted into a pin insertion hole leading to the slit aperture.
