PINION SHAFT FIXING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide pinion shaft fixing structure low in costs and positively preventing slip-out and turning with simple structure while facilitating assembly work without requiring troublesome adjustment work or extra parts. SOLUTION: In the fixing structure of a pinion shaft 2 disposed orthogonally to a rotation axis L of a differential case 1, an endless ring member 3 axially mounted to the outer peripheral surface 1A of the differential case is adjusted to abut on a locking part 4 formed at the pinion shaft 2. The pinion shaft 2 can be positively and effectively prevented from slipping out and turning at a low cost only by axially moving and mounting the endless ring member 3 of simple structure without requiring other special members.
