ケース１に支持するパイロットベアリングである。[Prior Art] As shown in FIG. 5, the general structure of a differential (differential device) for automobiles, etc. is that a hypoid binion 2 is engaged with a ring gear 4 fixed to a differential case 3 in a carrier case l. In the differential case 3, there are four differential binions 6 that are rotatably fitted to the cross-shaped shaft of the spider 5.
and two side gears 7 that mesh with these, and the spider 5 is supported by the differential case 3. Left and right axle shafts (not shown) are connected to the side gears 7.7 by splines, respectively. In addition, 1° is a bearing cap for fixing the bearing 11 to the carrier case 1, 8 is a cap mounting bolt, 8a is a lock bolt, 8b is a deck case mounting bolt, Be is a ring gear mounting bolt, 9 is a collar, and 10 is a lock plate. ,
12 and 13 are nuts, 14 is a washer, 15 is an axle shaft axis, and 17 is a pilot bearing that supports the hypoid pinion 2 on the carrier case 1.

のすべりを防止している。With the above structure, when the hypoid pinion 2 is driven, the ring gear 4, differential case 3, and spider 5 rotate integrally around the axle shaft axis 16, and accordingly,
When the vehicle is traveling straight, the differential gear 7 rotates around the axle shaft axis 15 without rotating on its own axis, causing the side gear 7 to rotate, causing the left and right axle shafts (not shown) to rotate at a constant speed or in both ψ directions. When the wheels are changed, there is a difference in the number of rotations between the left and right wheels, so the differential rotation 6 rotates on its own axis to adjust the difference in number of rotations and prevent the tires from slipping.
