ABSTRACT:
The object of the present invention is to provide a rubber crawler in which a shape of the central lug viewed from a lateral side of the rubber crawler is approximately in the form an arc. Therefore, at a time of driving of the rubber crawler repeating back and forth movement, even if a large resisting force from the road surface due to an impediment, such as gravel, is subjected to the central lug particularly disposed close to a sprocket engagement section, the resisting force can be parried for dispersion to a suitable degree by such arrangement, so that there is no possibility of early peel occurring in the central lug or such peeling is prevented from extending to tread members connected thereto; thus, the life is prolonged.
