<p><P>PROBLEM TO BE SOLVED: To suppress or prevent fretting wear of a pin 20 for fixing a pinion shaft 15 while surely preventing dropping-out of the pin 20 without adversely affecting the efficiency of assembling work of a differential 1 in a structure adapted to lock and fix the pinion shaft 15 to a differential case 6 by inserting the pinion shaft 15 to a through hole 25 provided in a circumferential wall part of the differential case 6, and inserting the pin 20 to a pin insert hole 30 bored in a circumferential wall part of the differential case 6 orthogonally to the through-hole 25 to thereby engagingly lock the pin 20 by the pinion shaft 15. <P>SOLUTION: A receiving surface 33 for receiving the inserting directional front end side of the pin 20 inserted to the pin insert hole 30 is provided on the deep side of the pin insert hole 30, and the pin 20 is pressed from the insert directional rear end side by a pressing member 40. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
