PROBLEM TO BE SOLVED: To provide a crawler running device capable of preventing sediment from being deposited on running frames. SOLUTION: In this crawler running device 2, a crawler 15 is wrapped between a driving wheel 12 supported on the running frame 3 and a driven wheel 14 supported on an arm 13 slidably inserted in the running frame 3. An inclined surface 3e gradually lowered from the inside of the running frame 3 toward the outside is formed on the upper part of the running frame 3. Sediment dropped on the running frame 3 is discharged to the ground along the inclined surface 3e, whereby cleaning work for the running frame 3 after maintenance can be reduced. A guide plate 3g is provided in the running frame 3 to thereby improve the longitudinal strength of the running frame 3.
