あった。However, in the vibration damping device for the propeller shaft as in the conventional example described above,
The support ring having a C-shaped cross section is configured to be fixed in the hollow propeller shaft by utilizing a spring force obtained through a notch provided at one position, and is supported on the entire circumferential surface of the support ring. In order to achieve this, it is desirable to apply a spring force that uniformly spreads in the radial direction on the entire circumferential surface, but due to the structure, the spring force does not act uniformly, and it is strong in the region where the spring force strongly acts in the circumferential direction. A non-acting region may occur, and it may be difficult to stably support the vibration damping device in the propeller shaft, resulting in idling. Further, when the spring force of the support ring is reduced due to heat or the like, there is a problem that the vibration damping force may be diminished by causing the support ring to idle in the hollow propeller shaft.
