<P>PROBLEM TO BE SOLVED: To provide a differential gear for a vehicle which realizes the suppression of the occurrence of seizure and eccentric wear on a sliding part of a pinion gear and a supporting surface thereof, and the acquisition of a favorable meshing state of the pinion gear and side gear. <P>SOLUTION: In a differential case which comprises side gears 5L, 5R, pinion gears 3, 4 meshing with the side gears 5L, 5R by making a gear shaft intersect perpendicularly thereto and a differential case 2 for freely rotatably accommodating the pinion gears 3, 4 and side gears 5L, 5R, the differential case 2 consists of a case body 2A rotated by receiving torque from a driving source and pinion gear insertion members 2B, 2C inserted into axial holes 30A, 40A opening in gear axial directions of the pinion gears 3, 4. The pinion gear insertion members 2B, 2C includes pinion gear supporting surfaces 210B, 210C for freely rotatably supporting the pinion gears 3, 4 through the slide on the inner peripheral surfaces of the axial holes 30A, 40A. <P>COPYRIGHT: (C)2009,JPO&INPIT |
