<p><P>PROBLEM TO BE SOLVED: To smoothly lubricate a clutch part. <P>SOLUTION: An oil seal 159 is arranged between a joining shaft 163 of an axle 39 and a support housing 51. Since an annular space part 115 for temporarily storing lubricating oil to be circularly supplied to the clutch part 49 is arranged between the axle 39, an electromagnet 99, the support housing 51 and the oil seal 159, the lubricating oil temporarily stored in the annular space part 115 can be used to be circularly supplied to the clutch part 49 more than a structure for lubricating only by scraping up the lubricating oil, and the clutch part 49 can be smoothly, surely and sufficiently lubricated. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
