A crawler belt type traveling system which ensures improved durability in
the portions near road wheel rolling contact sections. The system
comprises crawler belts formed from an elastic material such as rubber and
road wheels attached to a vehicle body. Each crawler belt has core bars
embedded therein so as to be aligned at specified intervals in a
longitudinal direction of the crawler belt. Each core bar has a pair of
guide projections at the center thereof with respect to a widthwise
direction of the crawler belt, the pair of guide projections being aligned
in a widthwise direction of the crawler belt. Provided at both sides of
the pair of guide projections are road wheel rolling contact sections.
Each road wheel comes into contact with the road wheel rolling contact
sections, for supporting each crawler belt. In such a system, the tread of
each road wheel comes into contact with the road wheel rolling contact
sections of the crawler belt, being away from the root parts of the guide
projections of the crawler belt.
