Abstract
A vibration damping apparatus including a support member rotatable together with a rotational element, a restoration force generating member coupled to the support member to transmit and receive a torque with the support member, an inertial mass coupled to the support member via the restoration force generating member, a first guide surface on the restoration force generating member, a second guide surface on the inertial mass, and a coupling member having first and second rolling portions. The first and second guide surfaces are formed so that the first rolling portion rolls along the first guide surface and the second rolling portion rolls along the second guide surface along with rotation of the support member causing the restoration force generating member to swing about a rotation center of the rotational element along a radial direction of the support member and causing the inertial mass to swing about the rotation center.
