PROBLEM TO BE SOLVED: To provide a rubber crawler traveling device for agricultural machinery such as a combine and construction machinery to reduce vibration transmitting to an operator seat capable of eliminating such problems that the crawler traveling device vibrates vertically caused by a variation in tension following the intermittent driving of a crawler by a sprocket, the core of the rubber crawler drops into a tooth groove part between the tooth parts of the sprocket, and the fluctuation of the rubber crawler becomes large to impactly excite the sprocket so as to generate vibration and noise to the operator seat and cause a damage to the core and the sprocket. SOLUTION: Disk-like support members 14 and 15 are provided on both right and left sides or on one side of the sprocket 5 and the outer peripheral surfaces of the support members 14 and 15 are positioned between the pitch circle 5d and the tooth bottom part 5b of the sprocket 5 near the tooth bottom part 5b.
