PROBLEM TO BE SOLVED: To efficiently transmit driving force from a drive sprocket to a crawler belt, and to improve the thrust of a crawler traveling device.SOLUTION: A crawler traveling device is equipped with a drive sprocket 12 for driving a crawler belt 11 by a plurality of drive pressing portions 25; and outer rolling type front side idling wheel and rear idling wheel, and a plurality of rolling wheels 15 for guiding the crawler belt 11 by right and left wheel bodies 29. A plurality of drive projecting portions 22 projecting at a right and left center side place on an inner peripheral surface of the crawler belt 11, are composed of a plurality of core projections 21B of core metals 21 embedded in the crawler belt 11, and a coating portion 11B of the crawler belt 11 covering the core metal projections 21B. Each drive projecting portion 22 is equipped with a pressed surface 22B receiving a pressing surface of each drive pressing portion 25 and pressed. Each pressed surface 22B is formed so as to make length in a projecting direction over the total length in a right and left width direction equal to or longer than length in the projecting direction of the pressing surface. |
