Abstract
A lockup clutch for a torque converter is provided with a friction lining. The friction lining is divided into a radially-outer-side friction lining and a radially-inner-side friction lining. μ-ν characteristics of the radially-outer-side friction lining have a positive gradient to inhibit occurrence of a shudder by a stick-slip which takes place. The radially-inner-side friction lining is equipped with a large coefficient of static friction to provide large torque capacity during a clutch engagement. The radially-outer-side friction lining is bonded on a side of a piston in said lockup clutch.
