The invention provides an elastic track which improves durability, light weight and edge crack resistance in a balanced manner. The elastic crawler (1) comprises a crawler body (2), a core body (3) and a tensile body (4). The core has: a center part (7); a first base part (8) having a first surface (8a) formed on the inner peripheral side (cI) of the crawler on the outer side of the center part in the width direction (b) of the crawler; a second base part (9) having a second surface (9a) formed on the inner peripheral side of the crawler on the opposite side of the center part from the first base part; and a first wing part (10) extending from the first base part to the outer side in the width direction of the crawler. And a second wing section (11) extending from the second base section to the outside in the width direction of the track. The thickness (t2) of the second base portion in the track thickness direction (c) is smaller than the thickness (t1) of the first base portion in the track thickness direction. Protrusions (12) protruding toward the outer peripheral side (co) of the track are provided in a region including the outer end (9b) of the second base.

    本发明提供均衡地提高耐久性、轻型化和耐边裂性的弹性履带。弹性履带(1)包括履带主体(2)、芯体(3)和抗拉体(4)。芯体具有:中心部(7)、在中心部的履带宽度方向(b)的外侧且在履带内周侧(ci)形成有第1面(8a)的第1基部(8)、在相对于中心部与第1基部相反的一侧且在履带内周侧形成有第2面(9a)的第2基部(9)、从第1基部向履带宽度方向的外侧延伸的第1翼部(10)及从第2基部向履带宽度方向的外侧延伸的第2翼部(11)。第2基部的履带厚度方向(c)的厚度(t2)小于第1基部的履带厚度方向的厚度(t1)。在第2基部的包含外端(9b)的区域设置有向履带外周侧(co)突出的凸部(12)。
