Abstract
An inner periphery driving type rubber crawler comprises: a plurality of core metals buried in series in the rubber crawler along the longitudinal direction thereof such that the longer sides of each core metal are in parallel with the transverse direction of the crawler; a plurality of steel cords buried in the rubber crawler such that they surround the outer periphery of the core metals; a pair of horns which protrude from each core metal toward the inner side of the rubber crawler and which have a shape longer in said transverse direction than said longitudinal direction; and rubber members which cover sides of said horn in said longitudinal direction. The paired horns and the associated rubber members form a pair of driving protrusions. A sprocket of a driving wheel is inserted between the driving protrusions and is engaged with the protrusions via driving pins for transferring driving force to the rubber crawler. Rubber lugs are disposed in series at an outer peripheral face of the rubber crawler at an oblique angle such that one end of one lug is situated right above one metal core and the other end of the one lug is situated right above another metal core adjacent with the o…
