Rubber crawler

A rubber crawler comprising:

• an endless rubber body that is trained around a plurality of wheels;
• a main cord layer that is incorporated within the rubber body and includes a main cord extending around a rubber body circumferential direction;
• a first bias cord layer that is incorporated within the rubber body further to a rubber body circumferential outside than the main cord layer and is configured from first bias cords arranged side-by-side around the rubber body circumferential direction, the first bias cords extending at an angle with respect to the rubber body circumferential direction;
• a second bias cord layer that is interposed between the first bias cord layer and the main cord layer, and is configured from second bias cords arranged side-by-side around the rubber body circumferential direction and extending at an angle with respect to the rubber body circumferential direction so as to intersect the first bias cords;
• and
• a first reinforcement cord layer that is interposed between the first bias cord layer and the second bias cord layer, and is configured from reinforcement cords extending in a rubber body width direction, the reinforcement cords arranged side-by-side around the rubber body circumferential direction,
• wherein a second reinforcement cord layer is interposed between the second bias cord layer and the main cord layer.
