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 one metal core.

[ What is claimed is:] [1.] An inner periphery driving type rubber crawler for use with a vehicle having a driving wheel, the driving wheel having a sprocket and driving pins which stand upright to the sides of the sprocket comprising:a plurality of core metals having a substantially rectangular base which are 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 and the center of each core metal is aligned with the center in the transverse direction of the crawler;a plurality of steel cores which are buried in the rubber crawler such that said steel cords surround the outer periphery of the core metals;a pair of horns which protrude from said core metal toward the inner side of the rubber crawler and which have a shape longer in said transverse direction than said longitudinal direction; andrubber members which cover sides of said horn in said longitudinal direction,wherein said pair of horns and said rubber members form a pair of driving protrusions.
