Claims

[Scope of utility model registration request]

A rotationally driven differential case, a pair of rotatable worm gears arranged in series within the differential case and coupled to two output shafts, and a worm wheel and engagement spur gears provided on both sides of the worm wheel. The element gear has a plurality of sets of element gears rotatably provided in the differential case, each pair including a pair of engaging spur gears that mesh with each other and a worm wheel that meshes with each of the worm gears, The vehicular differential device that corrects a rotational difference between the two output shafts and distributes torque includes a cylinder chamber recessed in an inner surface of the differential case facing an end surface of at least one of the worm gears; a hydraulic pressure supply means for supplying hydraulic pressure to the chamber;
Differential restriction of a differential gear for a vehicle, comprising a piston that is slidably provided in the cylinder chamber and is pushed out of the cylinder chamber in response to hydraulic pressure supplied to the cylinder chamber and presses the one worm gear in the axial direction. mechanism.
