Claims

[Scope of utility model registration request]

A differential carrier, an accommodating portion having a cylindrical shape as a whole, and two lid portions that respectively close both ends of the accommodating portion are formed as an integral structure.
a differential case that is rotatably supported by the differential carrier and has a first opening in each of the lid portions about the rotation axis;
a differential case having a through hole and a plurality of second through holes opened in the radial direction in the housing portion, and a pair of worms rotatably disposed within the differential case. A total of two worms are provided such that each worm has a recess at the end facing the other worm, a pair of worms have a shoulder on the inner peripheral surface, and one spacer is arranged in the recess of each worm. at least one spacer is rotatable between the spacer formed so as not to protrude from the recess in which the spacer is disposed, and each of the first through holes of the differential case. an axle that is inserted into the worm and is non-rotatably coupled to the worm, and has a retaining ring, and the retaining ring is inserted into the worm from an end opposite to the end where the recess is provided. an axle hooked on the shoulder of the worm, and an element gear having a worm wheel in the center and spur gears at both ends, and meshing the adjacent spur gears in parallel; and a plurality of element gear sets in which each of the worm wheels is engaged with an opposing worm, each set being rotatably disposed in the second through hole of the differential case. The second through hole of the differential case has a size that allows insertion of one worm having the one spacer arranged therein.
