PROBLEM TO BE SOLVED: To provide an elastic crawler capable of improving mud drain performance in a division groove, and suppressing increase of travel resistance, and a crawler travel device comprising the same.SOLUTION: An elastic crawler comprises: an endless belt-state elastic body 40 wound around a drive wheel 11 and idler wheel 12; a support part 71 formed on an inner peripheral surface of the elastic body 40 in a projecting state, contacting outer peripheral surfaces of the drive wheel 11 and idler wheel 12 for supporting them; and a division groove 91 for dividing the support part 71 in a peripheral direction of the elastic body 40. A cross sectional area of the division groove 91 in a peripheral direction cross section of the elastic body 40 becomes larger as going to outside of the elastic body 40 in a width direction.
【課題】本発明は、分割溝内の泥捌け性を向上させ、走行抵抗の増大を抑制することができる弾性クローラおよびこれを備えたクローラ走行装置を提供する。【解決手段】駆動輪11および遊動輪12に巻き掛けられる無端帯状の弾性体40に、その内周面に隆起して形成され、前記駆動輪11および遊動輪12の外周面に当接して支持する支持部71と、前記支持部71を前記弾性体40の周方向に分割する分割溝91と、を備え、前記弾性体40の周方向断面における前記分割溝91の断面積が前記弾性体40の幅方向外側に大きくなるように構成される。【選択図】図3
