<p>An elastic endless crawler, wherein cord projected parts at each end of a crawler main body are divided into some groups according to the projected length and, as viewed from vertical direction relative to a blet surface, the entire cord projected part at one end of the crawler main body can present a male-shape and the entire cord projected part at the other end of the crawler main body can present a female-shape, as viewed from a vertical direction relative to the belt surface, a line connecting the tips of the cord projected parts at the ends of the crawler main body to each other can be formed in a terrace, stepped, or serrated shape and, as viewed in the vertical direction relative to the blet surface, an overlapped part includes two outlines separated from each other in the longitudinal direction of a belt and both outlines can be formed of bent lines, whereby, because a difference in rigidity between a crawler mian body part including the overlapped part of steel cords and the other part can be reduced as much as possible, vibration and noise can be suppressed effectively from occurring, and because a boundary between a highly rigid part of the rubber crawler and the other part is formed distinguishingly, the possibility of occurence of bending and buckling of the rubber crawler is reduced to provide the rubber crawler excellent in durability and relability. <IMAGE></p> |
