PURPOSE:To work a function of a differential lock completely by a mechanism wherein oblique teeth are formed at the opposing end sections of two axles, and a pair of two pawl bodies mounted to a driving shaft and pivotally installed in switching-free shapes are disposed between the oblique teeth. CONSTITUTION:Oblique teeth 13, 14 are made up at the opposing sections of two axles 11a, 12a while a pin 17 is mounted to a drive member 21 so as to be inserted between the oblique teeth 13, 14, a pair of pawl bodies 15, 16 are pivotally installed in switching-free shapes by means of the pin 17, and the pawl bodies 15, 16 are formed in attachment-free shapes apart from the oblique teeth 13, 14. Consequently, the pawl bodies 15, 16 and the oblique teeth 13, 14 are connected and torque can uniformly be distributed and transmitted to both axles 11a, 12a even when one of the two axles 11a, 12a is brought to low load. Thus, the efficiency of a differential lock is increased to 100%, and a function of the differential lock can be worked completely.
