Abstract:
A lockup apparatus for a torque converter, which has a drive plate, a driven plate and damper springs connecting the drive plate and the driven plate in a rotating direction, is provided. Each damper spring has a pair of divided parts. An equalizer plate as an intermediate member is arranged so as to slide rotatably on bearing parts of the drive plate, and supporting parts fixed to the equalizer plate are arranged between the divided parts of the damper springs. A bearing part of the drive plate has an outer peripheral surface having an arc shape with a center or a curvature which is offset from a center of an arc shape of an inner peripheral surface of the equalizer plate.
