Claims

[Claims for Utility Model Registration] (1) An endless crawler body 2 made of an elastic material with lugs 5 protruding from the ground side, and a plurality of tensile bands 4 in the width direction.
In the elastic crawler formed by embedding the tensile strips 4 in the circumferential direction and polymerizing and bonding both ends 8 and 9 of each tensile strip 4, at least the outside in the width direction of each tensile strip 4 is covered with a canvas 10. An elastic crawler characterized by being encapsulated. (2) The elastic crawler according to claim 1, wherein the circumferential positions of the overlapping portions of each of the tensile bands 4 are slightly shifted. (3) The elastic crawler according to claim (1), wherein at least the outer tensile band end portion 8 of the overlapping portion of each of the tensile band members 4 is covered with a canvas 10. (4) The elastic crawler according to claim (1), wherein the canvas 10 is tape-shaped and arranged at predetermined intervals in the circumferential direction. (5) The elastic crawler according to claim (1), wherein the canvas 10 covers the entire widthwise circumference of each tensile band 4. (6) The elastic crawler according to claim (1), wherein the core metals 3 are embedded at predetermined intervals in the circumferential direction. (7) The elastic crawler according to claim (1), wherein a plurality of the canvases 10 are stacked one on top of the other. (8) The elastic crawler according to claim (1), wherein the canvas 10 covers both outer sides in the width direction of each tensile band 4 and is arranged over the entire width of the lug 5 side.
