Abstract: According to an embodiment, a damping device includes a base member including a first base and a second base, a weight member, a pair of first base-side coil springs provided between the first base and the weight member, and a pair of second base-side coil springs provided between the second base and the weight member. Each of the first base-side coil springs includes a first effective turn portion, a first fixed pin portion supported in the first base, and a first movable pin portion supported in the weight member. Each of the second base-side coil springs includes a second effective turn portion, a second fixed pin portion supported in the second base, and a second movable pin portion supported in the weight member.

Abstract: A damping device according to one embodiment includes a base member fixed to a vibration suppression target, a first coil spring, a second coil spring, and a weight member. The first coil spring includes a first fixed-side end turn portion supported on a first support portion of the base member, a first effective portion, and a first movable-side end turn portion. The second coil spring includes a second fixed-side end turn portion supported on a second support portion of the base member, a second effective portion, and a second movable-side end turn portion. Each of the first coil spring and the second coil spring is deflected in a longitudinal direction along the axis, and a transverse direction perpendicular to the axis. The weight member is arranged between the first coil spring and the second coil spring, and moves in the longitudinal direction and the transverse direction.
