A bias ratio levelling apparatus for a worm gear type differential include first and second shafts mounted on a common axis first and second worm gears fixedly provided in the rotational direction at opposed end portions of the two shafts, a first worm wheel directly intersected with the shafts and engaged with the first worm gear, a second worm wheel directly intersected with the shafts and engaged with the second worm gear, a rotatable member for rotatably bearing the first and second worm wheel about a central axis and for rotating first and second worm wheel about the first and second shafts. A spur gear is fixedly connected to each worm wheel for transmitting the rotation of one worm wheel to the other worm wheel by synchronization, and a spacer is interposed between the first and second worm gears and axially fixed to the rotational member in the direction of the first and second shafts.
