The present invention easily detects the breakage of a steel cord and easily determines the position of the breakage. An elastic crawler (11) is provided with: a crawler body (11a) formed in a ring shape and comprising a rubber-like elastic body; a tensile body (40) built in the track body (11a) and wound in the circumferential direction of the track body (11a); and a plurality of metal cores (30) built in the crawler body (11a) and disposed at intervals in the circumferential direction of the crawler body (11a). In an elastic crawler (11), a tensile body (40) is configured from a steel cord (41) wound in a spiral shape along the circumferential direction of a crawler body (11a). In an elastic crawler belt (11), a steel cord (41) is configured such that one end (41a) and the other end (41b) in the longitudinal direction of the steel cord (41) and an intermediate section (41c) located between the one end (41a) and the other end (41b) are electrically connected to different metal cores (30).
本发明容易地检测钢帘线的断线且简易地确定断线位置。弹性履带(11)具备:履带主体(11a),由橡胶状弹性体构成且形成为环状;抗拉体(40),内置于履带主体(11a)并在该履带主体(11a)的周向上卷绕;以及多个金属芯(30),内置于履带主体(11a)并在该履带主体(11a)的周向上隔开间隔地配置。在弹性履带(11)中,抗拉体(40)由沿着履带主体(11a)的周向卷绕成螺旋状的钢帘线(41)构成。在弹性履带(11)中,钢帘线(41)构成为,该钢帘线(41)的在长度方向的一端部(41a)和另一端部(41b)以及位于一端部(41a)与另一端部(41b)之间的中间部(41c)分别与不同的金属芯(30)电连接。
