<p><P>PROBLEM TO BE SOLVED: To provide a wet type multiple disc clutch for supplying lubricating oil from the inner peripheral face of a cylindrical part of a clutch hub via lubrication holes to a plurality of plates while properly supplying the lubricating oil between the plates even during idling neutral control. <P>SOLUTION: The cylindrical part 13 is parted into a plurality of regions k having the same lengths in the peripheral direction. The plurality of lubrication holes 13a mutually different in axial position are formed as one lubrication hole set m in each region k, while the plurality of lubrication holes 13a constituting one lubrication hole set m are dislocated in the peripheral direction. An annular weir 13c protruding inward in the radial direction is provided at the opening end of the cylindrical part 13. The inner diameter of the weir 13c is set to be not larger than a diameter r of a circle concentric with the cylindrical part 13 which is connected to a line i connecting both peripheral ends of the inner peripheral face in each region k of the cylindrical part 13. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
