Abstract
A dynamic damper for suppressing vibration generated by a gear attached to a rotation shaft, the dynamic damper, includes: a mass body that is disposed inside a rotation shaft having a hollow shape and extends along a shaft center of the rotation shaft; and an elastic body that couples the mass body to the rotation shaft. Further, a flow path for lubricating liquid to flow is provided between an inner peripheral surface of the rotation shaft and the mass body, and the flow path is formed by the inner peripheral surface of the rotation shaft at an axial position where the elastic body is disposed.
