<p>PURPOSE:To obtain a friction surface with a high magnetic characteristic further with a high friction coefficient, by using a ferrite material for frictional members which form the friction surface forced to be brought into pressure contact. CONSTITUTION:Friction materials 7, 9 are secured to opposed surfaces of clutch plates 6, 8. The friction materials 7, 9 use those sintered by ferrite. By this constitution, the friction materials 7, 9, which contain metal and alloy of a divalent metal ion enhancing a friction coefficient further with porous sintering, obtains a high friction coefficient further a high magnetic characteristic.</p> |
