<P>PROBLEM TO BE SOLVED: To provide a power transmission for a vehicle efficiently cooling a coupling while easing short of working fluid in a differential housing by preventing working fluid from unevenly exist in a coupling case. <P>SOLUTION: A return passage returning working fluid supplied into the coupling case 3 to a ring gear side is provided on the differential housing. A working fluid lead member 63 leading working fluid rotating in a coupling outer circumference together with rotation of the coupling to an inlet part of the return passage is provided at a part of an inner wall of the coupling case 3 corresponding to the coupling. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
