PROBLEM TO BE SOLVED: To provide an elastic crawler in which an end part in a width direction is hardly bent when it passes through a projection article such as a curbstone. SOLUTION: The elastic crawler 1B includes a lug 4B having the whole part or a portion at an end side in a width direction inclined/extended to one side in a circumferential direction making an inner side in the width direction as an origin. The lug is projected such that a side surface directed to one side in a circumferential direction is inclined to the other side in the circumferential direction and a side surface directed to the other side in the circumferential direction is inclined to one side in the circumferential direction. In the side surface directed to one side, a portion 20B at an end side including an end in the width direction has a degree of inclination relative to a virtual flat surface determined in a circumferential direction and a width direction being more moderate as compared with the other portion and is a flat surface for forming a cross line extending in a width direction while crossing to the virtual flat surface. The side surface directed to the other side has a front side surface 15 in which a degree of inclination is more moderate as compared with the other portion at the end side including the end in the width direction.
