    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 torsional vibration reducing device includes a rotating body, rolling bodies, and a connection member. The rotating body includes guide holes, and the connection member includes accommodating portions that has at least two contact portions. The accommodating portions are positioned in the guide holes, and the guide holes accommodate the rolling bodies. The accommodating portions are configured to hold the outer peripheral surface of each of the rolling bodies with the contact portions, in a direction in which the rolling body reciprocates.

    Abstract: A torsional vibration damper includes a planetary rotary unit and an elastic body that couples two rotary elements of three rotary elements so that the two rotary elements can rotate relatively to each other. The torsional vibration damper includes a shaft supporting member by which a rotation center axis of at least any one rotary element of the two rotary elements and a rotation center axis of the rotary element other than the planetary rotary unit and the two rotary elements are held on the same axis. The shaft supporting member has a holding section that is disposed in a position between fellow planetary rotary elements and not making contact with the planetary rotary elements and that fits with and thereby suppresses movement of the rotary element other than the planetary rotary unit and the two rotary elements in the axial direction.

    Abstract: A vibration damping device that can prevent interference between a rolling mass and a cover resulting from deformation of the cover caused by pressure rise, and that can suppress noises is provided. The torsional vibration damping device comprises: a rotary member that is arranged in a torque converter; a rolling mass that is oscillated relatively to the rotary member by torque pulse; a bore that is formed on an outer circumferential portion of the rotary member in such a manner as to penetrates through the rotary member in a direction parallel to a rotational center axis; a cover that covers the rolling mass and the bore liquid-tightly to protect from oil in the torque converter; and a deformation-preventing member that prevents a deformation of the cover in a direction toward the rolling mass.
