Claims

[Scope of utility model registration request]

A center bearing mount that is installed in an automobile powertrain system that transmits the output from an engine to the drive wheels via a propeller shaft, elastically supports the intermediate portion of the propeller shaft on the vehicle body by means of a center bearing mount having an elastic member. In powertrain system vibration prevention devices that prevent vibrations,
a driving state detecting means for detecting the driving state of the automobile; and a rigidity variable means that operates based on the detected state of the driving state detecting means and can change the rigidity of the center bearing mount in cooperation with the elastic member. A powertrain system vibration prevention device characterized by having the following.
