<p><P>PROBLEM TO BE SOLVED: To provide a differential gear unit in which precise fit-holes for planetary gears are bored simply, and the whole cost can be reduced. <P>SOLUTION: The differential gear unit comprises a 1st sun gear 3 where a 1st shaft 1 is interlocked, a 2nd sun gear 4 where a 2nd shaft 2 is interlocked, 1st planetary gears 5 meshed respectively with the 1st sun gear 3, 2nd planetary gears 6 which are rotated together with the 1st planetary gears 5 and meshed with the 2nd sun gear 4, and a carrier 7 supporting the 1st and the 2nd planetary gears 5, 6. The carrier 7 has a 1st fit-hole 71 at the rotation center, and 2nd fit-holes 72, 72 at positions deviated from the rotation center, and allocated at equal intervals in the circumferential direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
