ABSTRACT:
A differential case for a vehicle and a differential device for a vehicle supplying sufficiently lubrication oil to a gear peripheral portion as a supported portion of a pinion gear in order to prevent a bonding of the gear peripheral portion of the pinion gear. The differential case or the differential device for the vehicle comprises a pair of pinion gear supporting portions (10, 11) supporting slidably a pair of pinion gears (3, 4), and a lubrication oil introducing portion (7, 8) provided around a peripheral portion of the pair of pinion gears (3, 4) to introduce lubrication oil into a clearance between sliding faces of the pair of pinion gears (3, 4) and pinion gear supporting faces (10a,11a,10b,11b) of the pair of pinion gear supporting portions (10, 11).
