Claims

[Claims for Utility Model Registration] Core metals 3 are embedded in an endless belt-shaped main body 2 made of an elastic material, extending in the width direction of the main body 2 and spaced at predetermined intervals in the circumferential direction. Elastic crawler tracks 1 each having a lug 8 corresponding to the core metal 3
In this, the core metal 3 is provided with a flat pressure receiving surface 6 parallel to the lug contact surface 8a at a position corresponding to the rolling surface 10 of the guide roller 9 on both sides of the center portion in the width direction of the main body 2 on the inner peripheral surface side, An elastic crawler track characterized in that a concave groove 12 is provided at or near the rolling surface 10 of the main body 2 that covers the pressure receiving surface 6.
