Abstract
A torque fluctuation inhibiting device is disclosed. The torque fluctuation inhibiting device includes an input member, an elastic member, a mass body and a centrifugal element. The input member includes a pair of input plates disposed in axial alignment. The input member is disposed to be rotatable. The elastic member is held by the pair of input plates. The mass body is disposed to be rotated with the input member and be rotatable relative to the input member. The centrifugal element is disposed to be radially movable by a centrifugal force acting thereon in rotation of the input member. The centrifugal element is disposed between the pair of input plates.

A torque fluctuation inhibiting device comprising:
- an input member disposed to be rotatable, the input member including a pair of input plates, the pair of input plates axially aligned;
- an elastic member held by the pair of input plates;
- a mass body disposed to be rotated with the input member and be rotatable relative to the input member;
- and
- a centrifugal element disposed between the pair of input plates, the centrifugal element disposed to be radially movable by a centrifugal force acting thereon in rotation of the input member, and the centrifugal element disposed radially outside the elastic member;
- wherein the pair of input plates is disposed apart from each other at an interval at outer peripheral parts thereof while making contact with each other at inner peripheral parts thereof.
A torque fluctuation inhibiting device comprising:
- an input member disposed to be rotatable, the input member including a pair of input plates, the pair of input plates axially aligned;
- an elastic member held by the pair of input plates;
- a mass body disposed to be rotated with the input member and be rotatable relative to the input member without being sandwiched by the pair of input plates;
- and
- a centrifugal element disposed between the pair of input plates, the centrifugal element disposed to be radially movable by a centrifugal force acting thereon in rotation of the input member;
- wherein the pair of input plates is disposed apart from each other at an interval at outer peripheral parts thereof while making contact with each other at inner peripheral parts thereof.
