Abstract: Disclosed is an elastic crawler formed with an elastic material in the shape of an endless track, and used as the wheel for the work vehicle with enhanced reliability and durability. The elastic crawler includes a crawler body formed with an elastic material and having lugs protruded at the ground contact side thereof, and cores having wings extended left and right to the center of the crawler body in the width direction thereof, and arranged parallel to each other in the longitudinal track direction of the crawler body such that the wings face the lugs formed at the crawler body. The crawler body has first and second lug units alternately arranged parallel to each other in the longitudinal track direction thereof. The first lug unit has left lugs facing each other over two wings, and right lugs arranged right to the center of the crawler body while proceeding symmetrical to the left lugs around the center.

Abstract: The present invention provides an elastic crawler having an improved flexing properties in which arrangement of lugs are improved so as to prevent deterioration of the flexing properties due to rigidity of a crawler body increased by providing lugs. The crawler includes a crawler body 2, a plurality of core members 3 having right and left wings 3R, 3L, respectively, and provided in the crawler body laterally with respect to the crawler and in parallel to each other with a space therebetween in the longitudinal direction of the crawler, and a plurality of right and left lugs including small lugs provided correspondingly to one of the wings 3R or 3L and large lugs provided correspondingly to two of the wings 3R or 3L adjacent to each other in the longitudinal direction of the crawler.
