    Abstract: A torsional vibration reducing device includes: a rotating body; an inertial body; a coupling member configured to transmit the torque to the rotating body and to the inertial body; and a first coupling portion and a second coupling portion, which are separately provided to either the rotating body or the inertial body The first coupling portion engages with the coupling member so as to: restrict movement of the coupling member in a rotational direction of the rotating body; and allow movement of the coupling member in a radial direction of the rotating body. The second coupling portion engages with the coupling member such that when the rotating body and the inertial body rotate relative to each other, a contact portion of the coupling member with respect to the first coupling portion moves in the radial direction of the rotating body.

    Abstract: There is provided a vibration damper which is capable of damping torsional vibrations by pendulum movement of a plurality of inertial masses, and damping vibrations of plurality of order without letting the inertial masses to interfere.A distance between a center of curvature of an inner surface of a first through-hole and a center of curvature of an inner surface of a second through-hole formed in a rotary member is shorter than a distance between a center of curvature of an inner surface of a fifth through-hole and a center of curvature of an inner surface of a sixth through-hole formed in a first inertial mass. Moreover, a distance between a center of curvature of an inner surface of a third through-hole and a center of curvature of an inner surface of a fourth through-hole in a rotary member is longer than a distance between a center of curvature of an inner surface of a seventh through-hole and a center of curvature of an inner surface of an eighth through-hole formed in a second inertial mass.

    Abstract: A pendulum torsional-vibration reducing device includes: a rotor having a plurality of through-holes formed in the rotor with predetermined intervals in a circumferential direction of the rotor; a rolling element disposed in the through-holes so as to carry out pendular movement; and a casing fixed to the rotor so as to cover the rolling element, wherein the casing includes fixing pieces in tight contact with both side surfaces of the rotor so as to hold the rotor therebetween, and a thickness of the rotor at a position where the fixing pieces are in tight contact is thinner than a thickness of the rotor at a position where a rolling surface to which the rolling element is pushed by centrifugal force is formed.

    Abstract: A torsional vibration reducing apparatus is provided. The torsional vibration reducing apparatus includes a rotating body having a rolling chamber, and a rolling body including a support shaft portion, a first flange portion, a second flange portion, a first corner portion, and a second corner portion. The support shaft portion is housed in the rolling chamber. The flange portions are located respectively at either end of the support shaft portion in an axial direction. A position defined by the support shaft portion and the first flange portion is the first corner portion, and a position defined by the support shaft portion and the second flange portion is the second corner portion. In a section of the rolling body that is along a central axis of the support shaft portion, sectional shapes of the first corner portion and the second corner portion differ from each other.

    Abstract: A torsional vibration damper that can be arranged in a fluid coupling to downsize a powertrain is provided. The torsional vibration damper has a mass body held in a rotary member in such a manner to be oscillated by torque pulse of the rotary member. The rotary member is arranged in an internal space of a fluid coupling in which a pump impeller, a turbine runner and a predetermined stationary member are held in a casing. A planetary unit that performs a differential action among three rotary elements is arranged in the casing. In the planetary unit, a first rotary element is connected to the stationary member, a second rotary element is connected to the rotary member, and a third rotary element is connected to the turbine runner.
