Abstract
A vehicle differential apparatus including a pair of side gears arranged side by side along an axial line, a set of pinion gears disposed on a radial outside of the side gears so as to engage with the side gears and engaged with each other, and a housing forming a housing space of the pinion gears to rotate integrally with the pinion gears. Each of the side gears includes an inner and outer side gears, the inner and outer side gears include a first and second splines extended along helical gears formed on an outer and inner circumferential surfaces of the inner and outer side gears, respectively, and engaging with each other, and the helical gear of the first spline is formed so as to be crowned along a tooth trace thereof.
