Claims

[Scope of utility model registration request]

In the hollow propeller shaft that transmits the rotational force from the internal combustion engine through the transmission to the drive wheels,
The damper part is formed by an outer cylinder part to be press-fitted into a predetermined part inside the propeller shaft, a weight part provided inside the outer cylinder part, and a damping member that fixes the weight part inside the outer cylinder part and has a damping function. A propeller shaft characterized by the following configuration.
