A damper device includes first to third rotating elements rotatable about a rotational center; a first elastic element located between the first and third rotational elements and compressed by relative rotation of the first rotational element to the third rotational element in one rotational direction; a second elastic element located between the second and third rotational elements and compressed by relative rotation of the third rotational element to the second rotational element in the one rotational direction, a support member intervenient between the third rotational element and the first elastic element to support the first elastic element; and a restrictor provided with the third rotational element to rotatably support the support member in a plane orthogonal to the rotational center, to restrict the support member from rotating beyond a certain angle and from moving away from the third rotational element in rotational directions.

A clutch arrangement is provided with a mass damper system having a damper mass carrier and damper masses deflectable relative to the damper mass carrier. The clutch arrangement has a housing having at least two housing parts permanently connected to one another by a fixed connection, at least one housing parts has a cutout for at least one projection of the other housing part. The housing parts are assembled while receiving the damper mass carrier between an axial stop of the cutout of the one housing part and the projection of the other housing part. The housing parts are loaded over the course of producing the fixed connection by a clamping mechanism which acts on the housing parts in direction away from one another and operative axially between one of the housing parts and the damper mass carrier axially supported at the other respective housing part.

A damper device includes a first member, a second member, an elastic member and a supporting member. The first member has two wall members separated from each other. The supporting member includes projections (preventing portion) that make contact with one of two wall portions (wall members) so as to prevent the supporting member and an elastic member from being inclined (falling, rotationally moving) in the axial direction.

A damper device according to an embodiment includes first to third rotating elements rotatable about a rotational center; a first elastic element located between the first and third rotational elements and compressed by relative rotation of the first rotational element to the third rotational element in one rotational direction; a second elastic element located between the second and third rotational elements and compressed by relative rotation of the third rotational element to the second rotational element in the one rotational direction, a support member intervenient between the third rotational element and the first elastic element to support the first elastic element; and a restrictor provided with the third rotational element to rotatably support the support member in a plane orthogonal to the rotational center, to restrict the support member from rotating beyond a certain angle and from moving away from the third rotational element in rotational directions.

A damper comprised of a first rotary member; a second rotary member; at least one elastic member that transmits torque between the first rotary member and the second rotary member; a first seat member disposed between the elastic member, and a first abutment portion of the first rotary member and a second abutment portion of the second rotary member on a counter-rotating direction side of the first rotary member; a second seat member disposed between the elastic member, and the first abutment portion and the second abutment portion on a rotating direction side of the first rotary member; and a sticking preventing mechanism, which converts part of a radially outward force generated by a centrifugal force into a restoring force of the elastic member in the circumferential direction.

A torsional vibration damper, including: an axis of rotation; a drive plate; an output flange; and a spring retainer plate including a first side facing in a first axial direction, a second side facing in a second axial direction, and a plurality of spring stops formed of a same material forming the spring retainer plate. Each spring stop: extends from the first side at least partially in the first axial direction; and includes first and second circumferentially separated end surfaces separated, in the first axial direction, from the first side by first and second gaps, and a plurality of springs. Each spring includes a first circumferential end engaged with a respective first end surface and a second circumferential end engaged with a respective second end surface. The spring retainer plate partially surrounds the plurality of springs and retains the plurality of springs in a radially outward direction.

One embodiment provides a damper including: a first rotary member; a second rotary member; at least one elastic member that transmits torque between the first rotary member and the second rotary member; a first seat member disposed between the elastic member, and a first abutment portion of the first rotary member and a second abutment portion of the second rotary member on a counter-rotating direction side of the first rotary member; a second seat member disposed between the elastic member, and the first abutment portion and the second abutment portion on a rotating direction side of the first rotary member; and a sticking preventing mechanism, which converts part of a radially outward force generated by a centrifugal force into a restoring force of the elastic member in the circumferential direction.

A vibration damping device for an automotive vehicle includes a torque transmission plate, two rotatably connected guide elements that are coaxial along an axis of rotation and positioned on either side of the torque transmission plate, and helical compression springs bearing on the torque transmission plate and the guide elements by means of seats positioned on the ends of the springs. Each seat includes a frontal face suitable for interacting with the end of the springs, comprising a centring flange, the centring axis of which is coincident with the axis of the springs. A dorsal face defines a geometric plane backing onto the frontal part, and an indentation extending inwards from the dorsal face.
