PROBLEM TO BE SOLVED: To provide an unvulcanized molding material for a rubber crawler used in manufacturing rubber crawlers, capable of precluding the lowering of the running performance, durability, etc. resulting from meandering, waving, etc. of the tension resisting body of the rubber crawler manufactured. SOLUTION: The molding material for rubber crawler is furnished with a flat base part 15 to serve as the crawler body 3 after unvulcanization and projections 16 to serve as lugs 4 after vulcanization which are laid in line at a certain spacing as oriented in a certain direction on one side face of the base part 15, wherein the base 15 and the projections 16 are formed by an extrusion process in a single piece structure in the direction perpendicularly intersecting on the base 15 about the in-line formed direction of the projections 16.
