Claims

[Scope of Claim for Utility Model Registration] (1) A core bar arranged in the width direction at regular intervals in the circumferential direction within a track band body made of an endless rubber substance, and the outer periphery of both sides of the core bar in the width direction. In an elastic endless track belt in which a plurality of tensile members surrounding the side and arranged in the circumferential direction are buried integrally, and a grounding lug is formed in the width direction of the outer peripheral surface at a position corresponding to the core metal of the track belt main body, A stepped portion is provided along the width direction between the center portion of the circumferential width of the surface of the core bar facing the tensile body and both side edges, so that the center portion of the circumferential width is tensile than the both side edges. An elastic endless track belt characterized by a flat surface that protrudes toward the body side. (2) Claim (1) in which both side edges of the circumferential width of the surface of the core metal facing the tensile body are formed into sloped surfaces where the thickness of the core metal gradually becomes thinner toward the circumferential edge. The elastic track belt described. (3) A groove deeper than the embedding depth of the surface of the core metal on the opposite side of the surface facing the tensile member is provided along the width direction on the inner circumferential surface between adjacent core metals of the raceway band body. The elastic endless track belt according to claim (1) or (2). (4) The elastic endless track belt according to any one of claims (1) to (3), wherein a continuous or discontinuous groove is provided in the central projection area of the core metal circumferential width of the grounding lug of the track belt main body.
