PROBLEM TO BE SOLVED: To obtain an elastic crawler which prevents the derailment of an idler through the reduction in falling-down of a projection to the outside by preventing the deformation of a crawler body due to cutting of a tension body and by holding an idler with projections on laterally both sides. SOLUTION: An elastic crawler is equipped with a main tensioner 5 buried in a range of a crawler width direction through which an idler 22 passes and with a sub-tensioner 6 buried in laterally both sides of the main tensioner 5. The main tensioner 5 has a strength for securing a circumferential tensile strength of an elastic roller 1. The sub-tensioner 6 is buried in the more grounding side than the main tensioner 5 in the crawler thickness direction. COPYRIGHT: (C)2007,JPO&INPIT
