Claims (1)

[Scope of utility model registration request] In the track belt main body made of endless rubber substance, a core bar is arranged in the width direction at regular intervals in the circumferential direction, and a plurality of tensile members are arranged in the circumferential direction surrounding the outer circumferential side of the core bar. The ends of at least a pair of protrusions that are embedded integrally and protrude from the base of the core metal toward the inner circumferential side of the track belt main body for preventing derailment and/or for use as a wheel running track, extend in the circumferential direction. In an elastic endless track belt in which an extension part for the wheel running track is provided, and the space between this extension part and the track belt main body is filled with rubber substance, the tensile body is extended to the width of the protrusion of the core bar. The outer peripheral surface of the raceway belt main body includes a recess that is arranged in a region outside the outermost edge in the width direction and has an area that includes at least a part of the planar projection area of the extension of the protrusion of the core bar relative to the raceway belt main body. An elastic endless track belt characterized by being provided in the thickness direction from the point beyond the buried position of the tensile member to the inner circumference side.
