摘要：A rubber crawler having a specified rotation direction includes a crawler bodythat is formed in an endless shape and includes plural lugs. The plural lugs are providedat the crawler body, project out from an outer peripheral face, as viewed from a crawlerouter peripheral side, are allocated to one side and another side in a crawler width
direction so as to be alternately disposed on progression along the crawler peripheraldirection on each side of a central line passing through a crawler width direction center,and extend at an angle to the crawler peripheral direction from an end portion on thecentral line side toward a crawler width direction outer side and toward an opposite sideto a crawler rotation direction. In a cross-section of the lugs taken along the crawlerperipheral direction, an angle formed between each apex side portion of tread-in-sidewall faces on the crawler rotation direction side and the outer peripheral face is 90degrees or greater, and is smaller than an angle θ2 formed between each apex sideportion of a kick-out-side wall faces on the opposite side to the crawler rotationdirection and the outer peripheral face.
