<p><P>PROBLEM TO BE SOLVED: To provide a wet clutch capable of reducing drag torque. <P>SOLUTION: A wet clutch 1 comprises a yoke 5 having an inner peripheral friction surface 51b and an outer peripheral friction surface 51c, an armature 32 having an inner peripheral friction surface 32b and an outer circumferential friction surface 32c which are friction-engaged with the inner peripheral friction surface 51b and outer peripheral friction surface 51c of the yoke 5, and a first lubricating oil path 71 and a second lubricating oil path 72 which are used to supply a lubricating oil 9 between the inner peripheral friction surface 51b and the inner peripheral friction surface 32b and between the outer peripheral friction surface 51c and the outer peripheral friction surface 32c, the first lubricating oil path 71 and the second lubricating oil path 72 being used to supply the lubricating oil 9 in such an amount that air bubbles 90 are generated in the lubricating oil 9 by cavitation due to the relative rotation of the armature 32 to the yoke 5. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
