The present device includes an inertia ring, a plurality of centrifugal elements, a plurality of cam mechanisms and a plurality of restriction mechanisms. The inertia ring is disposed to be rotatable with a hub flange and be rotatable relatively to the hub flange. Each centrifugal element is disposed to receive a centrifugal force generated by rotation of the hub flange and the inertia ring. When a relative displacement is produced between the hub flange and the inertia ring in a rotational direction while the centrifugal force is acting on each centrifugal element, each cam mechanism converts the centrifugal force into a circumferential force directed to reduce the relative displacement. Each restriction mechanism allows actuation of each centrifugal element by each cam mechanism, and restricts radial movement of each centrifugal element.

Torque fluctuation inhibiting device, torque converter and power transmission device

A clutch device includes an input rotor, a first clutch, a second clutch, a first drive mechanism and a second drive mechanism. A first clutch is disposed switchably between a first transmitting state of transmitting power and a first blocking state of blocking power transmission. A second clutch is disposed switchably between a second transmitting state of transmitting power and a second blocking state of blocking power transmission. The first drive mechanism includes a first drive support member and the second drive mechanism includes a second drive support member. A drive clearance is configured to be produced axially between the first drive support member and the second drive support member in the first blocking state and the second blocking state. The drive clearance is less than a sum of the first stroke and the second stroke.

Clutch device

A clutch device includes an input rotor, a rotation support mechanism, a first pressure plate, a second pressure plate, a first clutch disc assembly and a second clutch disc assembly. The input rotor includes a first disc portion and a second disc portion disposed away from the first disc portion at a predetermined space. The rotation support mechanism supports the input rotor for allowing the input rotor to be rotated with respect to a first input shaft and a second input shaft.
