Abstract

A running pad for an endless track is disclosed, including resilient retaining projections which extend away from opposite sides of the running pad and are adapted to enter into locking engagement, at their free ends, in recesses formed in the respective chain links. The retaining projections are formed by the ends of a unitary resilient plate that extends through said running pad and is designed to yield elastically in a direction toward and away from the recesses of the chain link in order to allow simple and quick assembly of the running pad at the chain link in a direction vertical to the tread surface without the need of disassembly of the chain link.
