Title: VIBRATION DAMPING DEVICE
Abstract:
A vibration damping device having: a support member rotating around the rotation center of a rotation element; a recovery force generation member coupled to the support member; an inertia mass body coupled to the support member via the recovery force generation member; a guided section provided in the recovery force generation member or the inertia mass body; and a guide section formed in the inertia mass body or the recovery force generation member, having the component of centrifugal force acting on the recovery force generation member from the guided section transmitted thereto, and guiding the guided section such that, when the support member rotates, the recovery force generation member swings along the radial direction relative to the rotation center and the inertia mass body swings around the rotation center. The recovery force generation member includes two mass bodies coupled so as to face each other in the axial direction of the support member and arranged on both sides of the inertia mass body, in the axial direction.
