A traveling apparatus of a crawler vehicle can achieve both reduction of an impact applied to an operator cab and maintenance of high traction force even at a time of backward traveling on a ground surface having an irregularity. Right and left track frames (11, 11) are mounted to pivot shafts (31, 31) respectively mounted to right and left sides of a rear end portion of a main frame (30) so as to freely swing in a vertical direction, a rear frame (40) having a horizontal shaft apparatus (46) arranged therein is suspended to a rear portion of the main frame so as to freely swing in the vertical direction, final reduction gears (50) are attached to right and left outer sides of the rear frame, and an output shaft of the horizontal shaft apparatus is connected to an input shaft of the final reduction gear.
