To provide a rubber crawler for use in snow blowers that can obtain thrust without extremely losing the discharge property of snow entering an area between lugs even if the front part of the rubber crawler rises.

A pair of drive projections 17 is provided at the inner-periphery surface position of a band body 15 corresponding to a position where a long lug 16b is provided while opposing the direction of a band width. When length in the bandwidth direction of a driving gear 6a of a driving wheel 6 is set to be A, length in the bandwidth direction of a top section of a short lug 16a is set to be B, and length in the bandwidth direction of the top section of the long lug 16b is set to be C, the relationship is A<B<C.
