Damper device

A damper device configured to include an input element to which a torque from an engine is transmitted, an output element, an elastic body arranged to transmit a torque between the input element and the output element, and a rotary inertia mass damper with a mass body rotating in accordance with relative rotation between the input element and the output element, the damper device comprising:

• a stopper configured to restrict the relative rotation between the input element and the output element,
• wherein the rotary inertia mass damper is configured to include a planetary gear that includes a sun gear, a plurality of pinion gears that mesh with the sun gear, and a ring gear that works as the mass body,
• wherein the input element is configured to include a first rotational support member and a second rotational support member that are coupled with each other so as to be opposed to each other in an axial direction of the damper device, the first and the second rotational support members rotatably supporting the plurality of pinion gears,
• wherein the output element is configured to include a plurality of outer teeth gear portions arranged at intervals in a circumferential direction in the outer circumferential portion thereof so as to mesh with any of the plurality of pinion gears, the output element being disposed between the first and the second rotational support members in the axial direction so as to work as the sun gear,
• and wherein the stopper is configured to include a contact portion arranged in the outer circumferential portion of the output element so as to be located between the adjacent outer teeth gear portions in the circumferential direction and to contact with a portion of the input element in accordance with the relative rotation between the input element and the output element.

A damper device configured to include an input element to which a torque from an engine is transmitted, an intermediate element, an output element, a first elastic body arranged to transmit a torque between the input element and the intermediate element, a second elastic body arranged to transmit a torque between the intermediate element and the output element, and a rotary inertia mass damper with a mass body rotating in accordance with relative rotation between the input element and the intermediate element, the damper device comprising:

• a stopper configured to restrict the relative rotation between the input element and the intermediate element,
• wherein the rotary inertia mass damper is configured to include a planetary gear that includes a sun gear, a plurality of pinion gears that mesh with the sun gear, and a ring gear that works as the mass body,
• wherein the input element is configured to include a first rotational support member and a second rotational support member that are coupled with each other so as to be opposed to each other in an axial direction of the damper device, the first and the second rotational support members rotatably supporting the plurality of pinion gears,
• wherein the intermediate element is configured to include a plurality of outer teeth gear portions arranged at intervals in a circumferential direction in the outer circumferential portion thereof so as to mesh with any of the plurality of pinion gears, the intermediate element being disposed between the first and the second rotational support members in the axial direction so as to work as the sun gear,
• and wherein the stopper is configured to include a contact portion arranged in the outer circumferential portion of the intermediate element so as to be located between the adjacent outer teeth gear portions in the circumferential direction and to contact with a portion of the input element in accordance with the relative rotation between the input element and the intermediate element.
