Abstract:
A crawler belt link includes a center portion, one end portion located on one end side of the center portion, and the other end portion located on the other end side of the center portion. In a second surface, the center portion has a first portion of a rail surface, the one end portion has a second portion of the rail surface, and the other end portion has a third portion of the rail surface. A first outer circumferential portion reaching the second portion of the rail surface is located closer to a second side portion with respect to a bushing hole surrounding portion. Accordingly, a crawler belt link and a crawler belt apparatus can be implemented, by which wear of the rail surface above a bushing hole can be suppressed while maintaining the width of the crawler belt link to be relatively small.
