PROBLEM TO BE SOLVED: To reduce abrasion of lugs of a rubber crawler used for a wet field, and to improve propulsion and turning performance. SOLUTION: This rubber crawler for forming core metal embedded in an endless rubber elastic body, a steel cord embedded in the lengthwise direction of the endless rubber elastic body and the lugs on an outer peripheral surface, is constituted such that the lugs are formed by arranging straight line-shaped long lugs extending in the width direction of the rubber elastic body and short lugs between these long lugs, the lug height of a part opposed to the short lugs of the long lugs is lowered, and a swelling part is formed on the width edge of the rubber elastic body in the long lugs. 1... the endless elastic body, 10... the width edge, 2... the core metal, 7... the long lugs, 70... a lower height lug of a central part of the long lugs, 73... an inclined face for connecting the left and right long lugs 71 and 72 and the central part 70, 7a and 7b... the expanding part of the long lugs, 8... the short lugs, and 80... a foot part in the short lugs.
