The invention provides an elastic crawler (30) which can ensure rigidity and abrasion resistance of guide protrusions (6), can realize light weight, and contributes to improvement of knocking-over resistance. The elastic crawler (30) is provided with: a crawler body (60); and a guide protrusion (64) protruding from the runner passage surface (70) of the crawler body (60). The track body (60) includes a tensile body (42). The guide protrusion (64) includes a core (40). The tensile body (42) and the core body (40) are covered by an elastic member (38). The maximum width WC of the core (40) is smaller than the maximum width WR of the guide protrusion (64). The guide protrusion (64) is provided with a pair of outer side surfaces (76) located on the outside in the width direction. Each outer side surface (76) includes, in a portion thereof, a first core reflection region (90) having a shape along the shape of the core (40).

    本发明提供一种弹性履带(30),该弹性履带(30)能够确保引导突起(6)的刚性和耐磨性并实现轻型化,有助于提高耐脱圈性。该弹性履带(30)具备:履带主体(60);和引导突起(64),从履带主体(60)的转轮通过面(70)突出。履带主体(60)包括抗拉体(42)。引导突起(64)包括芯体(40)。抗拉体(42)和芯体(40)被弹性部件(38)覆盖。芯体(40)的最大宽度WC小于引导突起(64)的最大宽度WR。引导突起(64)具备在宽度方向上位于外侧的一对外侧面(76)。各个外侧面(76)在其一部分包括具有沿着芯体(40)的形状的形状的第一芯体反映区域(90)。
