ャリングとの間の相対回転により皿バネが摺動し、摩耗
が生じるという問題点があった。However, in the conventional slip limiting differential device, the disc spring is located between the side gear, which is a member of the rotary system, and the pressure ring, which is a member of the fixed system, with respect to the differential case. There has been a problem that the disc spring slides due to relative rotation with the pressure ring, causing wear.
このため、バックラッシュが変化（増大）し、皿バネの
付勢力を有効に利用することができなくなるという問題
点もあった。Therefore, the backlash changes (increases), and there is a problem that the biasing force of the disc spring cannot be effectively used.
本考案は従来の技術の有するこのような問題点に鑑みな

る。In order to achieve the above object, the slip limiting differential device according to the present invention forms a first cam portion on a side gear that meshes with a pinion gear and is floatingly arranged on an axle. A second cam portion to be engaged is formed on a drive gear splined to an axle, a clutch plate is arranged between the drive gear and the differential case, and a disc spring is arranged between the side gear and the drive gear. It will be done.

このため、サイドギヤとドライブギヤとの間に、相対回
転が生じることはない。従って、皿バネに摺動による摩
耗が発生することを防止することができる。Since the first cam portion of the side gear and the second cam portion of the drive gear are engaged with each other, relative rotation occurs between the side gear and the drive gear when a thrust action occurs. However, except when the thrust action occurs, the side gear and the drive gear rotate integrally.
Therefore, relative rotation does not occur between the side gear and the drive gear. Therefore, it is possible to prevent the disc spring from being worn due to sliding.
