Abstract

A dynamic damper device occupies a small space in an axial direction and can achieve a reduction in weight. The dynamic damper device is mounted to a turbine shell of a torque converter, and includes a damper plate, an inertia ring and a plurality of torsion springs. The damper plate is fixed to the turbine shell and is configured to be rotated. The inertia ring has spring accommodation parts and slider accommodation parts along a circumferential direction, and is disposed to be rotatable relative to the damper plate. The plurality of torsion springs are disposed in the spring accommodation parts of the inertia ring, and elastically couple the damper plate and the inertia ring in a rotational direction.
