portion is increased from the vicinity portion toward the inner circumference side end 19 b furthermore by increasing the distance between the vicinity portion of the inner circumference side end 19 b and the outer circumference side portion of the tensile cord 18 b to increase the thickness of an elastic body e 2 therebetween the elastic crawler 1 b can reduce a compressive strain of the elastic body e 2 in the vicinity of the inner circumference side end 19 b which is difficult to bend when traveling on the drive sprocket 4 or the like and realize improvement in fatigue resistance constituent elements of the tensile cord 18 b other than those described above are almost similar to those of the tensile cord 18 of the elastic crawler 1 preferably the range over which the increasing distance between the vicinity portion of the inner circumference side end 19 b and the outer circumference side portion of the tensile cord 18 b toward the inner circumference side end 19 b is provided as measured from the inner circumference side end 19 b is within a maximum distance which is a larger one of the distance between the centers of two adjacent metal cores 9 in the circumferential direction and the distance between the centers of the lugs 10 fig8 is a partial schematic cross sectional front view of an elastic crawler 1 c according to yet another embodiment of the present invention in the elastic.
