LOCKUP DEVICE FOR TORQUE CONVERTER

WIPO Patent Application WO/2014/123174

A1

Provided is a lockup device wherein the secondary resonance of a dynamic damper device is minimized and the dynamic damper device is made to work more effectively. The lockup device is provided with a drive plate (31), a driven plate (35) connected to a turbine (4), an intermediate member (34), a plurality of outer-periphery-side and inner-periphery-side torsion springs (32, 33), and a dynamic damper device (36). The intermediate member (34) is disposed between the outer-periphery-side torsion spring (32) and the inner-periphery-side torsion spring (33). The outer-periphery-side torsion spring (32) elastically connects the drive plate (31) and the intermediate member (34) in the rotation direction. The inner-periphery-side torsion spring (33) elastically connects the intermediate member (34) and the driven plate (35) in the rotation direction. The dynamic damper device (36) includes an inertia ring member (48) connected to the intermediate member (34).
