PROBLEM TO BE SOLVED: To provide a traveling vehicle improved in turning performance, making turns steplessly from a slow turn to a spin turn and to execute the smooth turn corresponding to the situation. SOLUTION: This transmission mechanism of a travel device for a working machine-shifts power from an engine and transmits the shifted power to axles through a differential mechanism. In this constitution, traveling drive force, and power through a shift means are inputted to the differential mechanism, and the combined power is outputted to the axle on the turning direction inner side. Furthermore, a slow turn wherein the axle on the turning direction inner side is rotated at low speed in the same direction as the axle on the turning direction outer side by the shift of power through the shift means, a pivotal turn wherein the axle on the turning direction inner side stops, and a spin turn wherein the axle on the turning direction inner side is rotated reversely to the axle on the turning direction outer side, can be continuously executed steplessly.
