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.

A crawler belt for use on a crawler motor vehicle has an elongate belt body drivable in a predetermined direction, and a plurality of ridges mounted on a ground contact side of the belt body, each of the ridges having at least one sipe defined in a free end thereof for allowing the ridge to be flexibly deformable in a direction opposite to the predetermined direction. Each of the ridges has a plurality of sipes defined therein and extending longitudinally thereof or substantially perpendicularly to the predetermined direction. The ridges comprise a plurality of chevron-shaped ridges pointing toward the predetermined direction and succesively arranged at predetermined spaced intervals in the predetermined direction. The ridges are divided into a plurality of groups each including a plurality of ridges by grooves extending transversely of the belt body, and divided into a plurality of segments by at least one longitudinal groove extending longitudinally of the belt body.
