An elastic endless crawler according to the present invention comprises an annular belt-shaped elastic crawler body and a plurality of cords with ends, said cords being disposed substantially parallel with one another at predetermined intervals and embedded in the crawler body, wherein one end and the other end of each cord are overlapped, as seen from the belt side. Further, at at least one of a crawler inner peripheral side and a crawler outer peripheral side, there are provided a plurality of members for holding the cord ends within the crawler body. As a result, a chance of free ends of embedded steel cords protruding out from the rubber body during use of the rubber crawler and a chance of the rubber crawler running off of a unit for driving for rotation thereof can be eliminated.

1. An elastic endless crawler comprising:an annular belt-shaped elastic crawler body and cords having ends, said cords being disposed substantially parallel with one another at predetermined intervals and embedded in the crawler body, such that both ends of each cord overlap along a longitudinal direction of the crawler body; driven protrusions, which are formed so as to protrude from an inner peripheral side of the crawler; and lugs, which are formed to protrude from an outer peripheral side of the crawler, wherein every end of the cords is located adjacent at least one of the driven protrusions and is located adjacent at least one of the lugs, the interval is at least twice as large as a cord diameter when the cord diameter is less than a predetermined value, the interval is at least one and a half times as large as the cord diameter when the cord diameter is at least the predetermined value and substantially every cord has a regularity in that one end of the cords is offset in a direction orthogonal to the crawler body longitudinal direction with respect to the other end of a same cord by substantially half the interval. 2. The elastic endless crawler of claim 1, comprising an annular surface extending in a peripheral direction of the rubber crawler, wherein substantially all of each cord is disposed within the annular surface.3. The elastic endless crawler of claim 1, comprising a one bias sheet that is embedded concentrically to the cords.4. The elastic endless crawler of claim 1, comprising a bias sheet having a characteristic of counterbalancing an urging force, which urging force is caused by the cord arrangement having said regularity.5. The elastic endless crawler of claim 1, wherein the cords are arranged so as to form a substantially symmetrical configuration relative to a centerline extending in the crawler peripheral direction.6. The elastic endless crawler of claim 1, wherein an outline, which connect the ends of one side of the cords and an outline which connect the ends of the other side of the cords each shows a stepped configuration, as seen from a side substantially perpendicular to the belt body.7. The elastic endless crawler of claim 1, the cords further comprising a first main cord and a second main cord, wherein a winding direction of the first main cord is the opposite of that of the second main cord, the first main cord and the second main cord being arranged in substantially the same surface and separated from each other relative to a centerline extending in the crawler lengthwise direction.8. The elastic endless crawler of claim 7, wherein bias cords or compensation cords are provided with a predefined bias angle whose winding direction is reversed from that of the respective main cords, said bias cords or compensation cords being juxtaposed with the main cords.9. The elastic endless crawler of claim 7, wherein the first main cords and bias cords, which has a winding direction opposite to that of the first main cords, are juxtaposed with each other, and the second main cords and bias cords whose winding direction is reversed from that of the second main cords are juxtaposed with each other.10. The elastic endless crawler of claim 8, wherein the bias cords are embedded more to an outer peripheral side of the crawler or more to a ground-contacting surface side than the main cords.11. The elastic endless crawler of claim 7, comprising cores embedded therein at predetermined intervals along the crawler lengthwise direction, wherein the main cords and the bias cords are embedded between the cores and a ground-contacting surface.
