PROBLEM TO BE SOLVED: To provide a traveling gear of crawler vehicle having a track frame, an idler and a sprocket in a substantially straight manner which compatibly mitigates shocks on a driver's cab and maintain a high tractive force when a crawler vehicle travels in the reverse direction on an uneven surface. SOLUTION: A track frame (11) is fitted around a pivot shaft (11a) provided on a main frame (9) in an oscillating manner, and a final reduction gear (30) including a sprocket (13) is fitted to a rear end portion (11b) of the track frame (11) so that the power is transmitted from a horizontal shaft device (50) on the main frame (9) side to an input shaft (31) of the final reduction gear (30) via an eccentricity permissible joint (32).
