PROBLEM TO BE SOLVED: To provide a crawler traveling device capable of facilitating engagement between the engaging recessed part of a crawler belt and the driving nail body of a driving sprocket. SOLUTION: A core metal projection 63 is covered with a rubber material. An engaging recessed part 62, to be engaged with the driving nail body 31 of a driving sprocket, is formed on the inner peripheral surface of a crawler belt 6. The engaging recessed part 62 is located between the right and left core metal projections 63 of core metals 61 arranged side by side in a belt peripheral direction, and an end surface in a belt width direction is formed into a tapered surface to be narrower toward the deep side. The driving sprocket is provided with, on the outer peripheral side of a disk-like member 30 fitted between the right and left core metal projections 63, a driving nail body 31 bulging in the horizontal direction of the disk-like member 30 inserted in the engaging recessed part 62 formed in the crawler belt 6 for each predetermined interval in the peripheral direction. The end surface of the driving nail body 31 in the horizontal direction is formed into a tapered surface to be narrower toward the outer side of a radial direction. COPYRIGHT: (C)2012,JPO&INPIT |
