Abstract
In a resilient crawler of this invention, sufficient flexibility at the portion between the lugs is obtained and such problems as separation of rubber are prevented while improving riding comfort by reducing the difference in rigidity between the portion where the lug is formed and the portion between the lugs, and improving lateral rigidity to assure the tractive force. Therefore, a resilient crawler of the present invention comprises a crawler body formed of a resilient material in the shape of an endless belt and having a multiplicity of lugs projecting from the outer peripheral surface at intervals longitudinally along the crawler body; and a multiplicity of linear lateral reinforcing members disposed in the crawler body so as to extend laterally thereof and be arranged longitudinally therealong. The lateral reinforcing members are arranged at close intervals with respect to each other in each portion E of the crawler body where the lug is formed, and at large intervals with respect to each other in each portion F between the lugs.
