To provide a core metal for an elastic crawler which is highly durable with respect torsion acting on the core metal during use, and to provide an elastic crawler using the core metal.SOLUTION: A core metal 30 for an elastic crawler comprises: a long core metal base body 31; a pair of projections 32L, 32R projecting from a longitudinal middle part of the core metal base body 31; and a pair of rail portions 34L, 34R projecting from the core metal base body 31 on outside of the pair of projections 32L, 32R and having a roller support surface 35 supporting a roller 56 rolling on an inner peripheral surface of the elastic crawler 10. A top surface 37 projecting from the core metal base body 31 and continuously formed from the roller support surface 35 has a pair of rail extensions 36L, 36R extending from the rail portions 34L, 34R toward the longitudinal middle of the core metal base body 31.SELECTED DRAWING: Figure 4

    【課題】使用時に芯金に作用するねじり力に対して高い耐久性を有する弾性クローラ用芯金及び該芯金を用いた弾性クローラを提供すること。【解決手段】長尺状の芯金基体31と、芯金基体31の長手方向の中央部にて突出する一対の突起部32L,32Rと、一対の突起部32L,32Rの両外側にて芯金基体31から突出し、弾性クローラ10の内周面を転動する転輪56を支持する転輪支持面35を有する一対のレール部34L,34Rと、を備えた弾性クローラ用芯金30において、芯金基体31から突出し、転輪支持面35から連続形成される頂面37が、レール部34L,34Rから芯金基体31の長手方向中央側に向かって延びる一対のレール延出部36L,36Rを備えた。【選択図】図4
