<p><P>PROBLEM TO BE SOLVED: To enhance lubrication efficiency of sliding faces of each friction slide-contact members, by catching lubricating oil splashing along an outer wall face of a clutch hub to guide the lubricating oil in the clutch hub. <P>SOLUTION: Inner circumferential side rising parts 25 and outer circumferential side rising parts 26 are formed at predetermined intervals on two circles with centers as an axial center of the outer wall face 12d of the clutch hub 12, so that the rising parts 26, 25 are risen with a state where sections 26a, 25a of the rising parts direct an axial center direction. Each outer circumferential side rising part 26 faces between neighboring inner circumferential side rising parts 25 and both ends of the section 26a are overlapped with the sections 25a of neighboring inner circumferential side rising parts 25. Therefore, the lubricating oil splashed along an outside face 12d by centrifugal force is caught by the sections 25a of the inner circumferential side rising parts 25, and the lubricating oil passing through the neighboring inner circumferential side rising parts 25 and splashing is caught by the sections 26a of the outer circumferential side rising parts 26 to be guided in the clutch hub 12. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
