PURPOSE:To enable to prevent an endless track shoe from bogging in a paddy or the like, by a method wherein the outside edges of the inside peripheral surfaces of ear parts on at least one side of an elastic track shoe are formed to be inwardly higher than a plane in which road wheels pass, and a flexible recessed region having a lower deformation resistance is provided in the longitudinal direction at the base of each of the ear parts. CONSTITUTION:The elastic endless shoe, namely, the crawler 6 is provided with the flexible recessed regions 8 having the lower deformation resistance, at the bases of the ears A on at least one side of the crawler 6 and on the outside of the straight line l-l connecting the outside ends of transverse metallic cores 1, and the outside edges 7 of the inside peripheral surfaces of the ears A are formed to be inwardly higher than the plane 9 in which the road wheels pass. When the crawler 6 enters a paddy and sinks, the flexible recessed regions 8 are so curved that the ears A are left behind concurrently with the deformation of ear edges, and the ears A take such positions as to ride on the mud layer on the adjacent side. Accordingly, the ears A of the stopped-side crawler 6 at the time of turning tend to ride onto the mud layer, while the driving-side crawler 6 guides the relative flow of mound ridge in the traveling direction along the ear edges, and travels while riding onto the mud. Accordingly, the vehicle can be turned smoothly. |
