PROBLEM TO BE SOLVED: To provide a rubber crawler reducing vibration causing bad riding comfort for an operator and failure and erroneous operation in electronic equipment, etc. equipped on a working machine. SOLUTION: This rubber crawler is constituted of an endless rubber elastic material, core metal buried into the rubber elastic material, a tensile body buried into the rubber elastic body, and a lug formed with the same pitch as that of the core metal on an outer peripheral side of the rubber elastic body. In the rubber, a plane shape of the lug at a portion facing to the core metal is formed into a substantially straight line in a width direction of the rubber elastic material, a cross-sectional shape of the lug in the longitudinal direction of the rubber elastic material is a substantially symmetrical trapezoidal shape, the widths of the core metal and the lug in the longitudinal direction of the rubber elastic material are almost the same, and the position of the lug is arranged by shifting in a direction opposite of an advancing direction. 1: rubber crawler, 2: rubber elastic material, 3: lug, 4: edge part of a top surface of the lug, 5: core metal, 6: engagement hole to teeth of a driving wheel.
