Abstract
A crawler belt apparatus includes a drive wheel having engaging teeth, a crawler belt having engaging projections engageable with the engaging teeth, and a plurality of discharge passages formed between root bottoms defined by the engaging projections, and top ends of the engaging teeth, for discharging foreign substances such as dirt and sand entered between the root bottoms and the top ends. The foreign substances passing through the discharge passages are not compressed by the drive wheel and hence do not become a solid mass.
