A crawler that has a specified rotation direction, the crawler comprising: a crawler body, that is formed from an elastic material in an endless shape, entrained around a drive wheel and a follower wheel (102, 104); a plurality of projections that project out from an inner peripheral face of the crawler body on a central line passing through a crawler width direction center of the crawler body at positions spaced apart from each other in a crawler peripheral direction; and a plurality of lugs that are provided at the crawler body, that project out from an outer peripheral face of the crawler body, that, as viewed from a crawler outer peripheral side, are allocated to one side and another side in the crawler width direction so as to be alternately disposed on progression along the crawler peripheral direction on either side of the central line, that extend at an angle to the crawler peripheral direction from an end portion on the central line side toward a crawler width direction outer side and toward an opposite side to a crawler rotation direction with a larger angle at an acute angle side with respect to the crawler peripheral direction on the crawler width direction outer side than on the central line side, and that have end portions on the central line side adjacent to each other in the crawler width direction, characterised in that corner portions are formed between the end portions on the central line and end portions at a crawler rotation direction side, respectively overlapping a single projection of the projections, and the lugs are disposed at positions separated in the crawler width direction with end portions on the central line side adjacent to each other in the crawler width direction respectively overlapping each other when viewed along the crawler width direction. a crawler body, that is formed from an elastic material in an endless shape, entrained around a drive wheel and a follower wheel (102, 104); a plurality of projections that project out from an inner peripheral face of the crawler body on a central line passing through a crawler width direction center of the crawler body at positions spaced apart from each other in a crawler peripheral direction; and a plurality of lugs that are provided at the crawler body, that project out from an outer peripheral face of the crawler body, that, as viewed from a crawler outer peripheral side, are allocated to one side and another side in the crawler width direction so as to be alternately disposed on progression along the crawler peripheral direction on either side of the central line, that extend at an angle to the crawler peripheral direction from an end portion on the central line side toward a crawler width direction outer side and toward an opposite side to a crawler rotation direction with a larger angle at an acute angle side with respect to the crawler peripheral direction on the crawler width direction outer side than on the central line side, and that have end portions on the central line side adjacent to each other in the crawler width direction, characterised in that corner portions are formed between the end portions on the central line and end portions at a crawler rotation direction side, respectively overlapping a single projection of the projections, and the lugs are disposed at positions separated in the crawler width direction with end portions on the central line side adjacent to each other in the crawler width direction respectively overlapping each other when viewed along the crawler width direction.
