To provide a core material for an elastic crawler capable of being returned to a normal position even when a skid or twist occurs, and to provide an elastic crawler.SOLUTION: A core material 3 for an elastic crawler is embedded in an endless belt-like crawler body made of an elastic body. The core material 3 for the elastic crawler includes a core material body 8 extending in a second direction b, a first projection 9A protruding to one side in a first direction a from the core material body 8, and a second projection 9B protruding to the other side in the first direction a from the core material body 8 on an inside bi in the second direction b beyond the first projection 9A. The first projection 9A is shaped to be convex toward an outside bo in the second direction b due to a first engagement surface 10A, a first flat surface, and a first curved surface. The second projection 9B is shaped to be convex toward the inside bi in the second direction b due to a second engagement surface 10B, a second flat surface, and a second curved surface.SELECTED DRAWING: Figure 3

    【課題】横ずれや捻れが生じたときにも通常の位置に容易に戻すことができる弾性クローラ用芯材及び弾性クローラを提供する。【解決手段】弾性体からなる無端帯状のクローラ本体に埋設される弾性クローラ用芯材3である。弾性クローラ用芯材3は、第2方向bに延びる芯材本体8と、芯材本体8から第1方向aの一方側に突出する第1突起9Aと、第1突起9Aよりも第2方向bの内側biで芯材本体8から第1方向aの他方側に突出する第2突起9Bとを含んでいる。第1突起9Aは、第1係合面10A、第1平面及び第1曲面により、第2方向bの外側boに向けて凸となる形状を有している。第2突起9Bは、第2係合面10B、第2平面及び第2曲面により、第2方向bの内側biに向けて凸となる形状を有している。【選択図】図3
