Claims

[Scope of Claim for Utility Model Registration] A crawler shoe made of endless rubber band that is wound between the driving wheel body and the idler wheel of the traveling drive device and has a rolling wheel passing surface through which the rolling wheels of the traveling drive device pass. , a rubber crawler having a core metal whose base is buried at appropriate intervals in the longitudinal direction of the crawler shoe, the core metal surface corresponding to the wheel passing surface is larger than the base width of the core metal in the longitudinal direction of the crawler shoe. A recess is formed in the crawler shoe between the core metals located on the roller passing surface, and a recess is formed on both sides of the recess in the width direction of the crawler shoe, or at least on the sprocket hole side, with a length in the longitudinal direction of the crawler shoe. A rubber crawler characterized by continuously forming large concave portions that are longer than concave portions.
