<P>PROBLEM TO BE SOLVED: To supply oil from one end side to the other end side of a hollow shaft in a rotary electric machine using a simple structure. <P>SOLUTION: A pair of notches 32, thorough which oil dripped from an oil supply port 13b pass, is formed on one end face 31a of a hollow shaft 31 so as to oppose to each other at a position shifted by 180° in the circumferential direction of the hollow shaft 31. The oil supplied from the oil supply port 13b passes through the notches 32, drips on an internal shaft 41, and flows into an oil flow passage 45. The oil flowed into the oil flow passage 45 flows from one end side to the other end side of the hollow shaft 31, and then reaches to a coupling part housing chamber 14a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
