Zusammenfassung:	PURPOSE: A vibration reduction device of a propeller shaft for a vehicle is provided to improve NVH(Noise Vibration Harshness) performance and a riding quality of the vehicle by reducing vibration due to unbalanced torque and the vibration inputted from a road. CONSTITUTION: A vibration reduction device(1) of a propeller shaft for a vehicle comprises a propeller shaft(3), a center bearing(5), a mounting bracket(7), and a damper unit(10). The propeller shaft receives power generated from an engine of the vehicle and transmits the power to an axle in order to drive the vehicle. The center bearing is installed in the propeller shaft in order to prevent resonance according to the rotation number of the propeller shaft and to improve rigidity of the propeller shaft. The mounting bracket is connected to the center bearing and fixes the propeller shaft to a vehicle body. The damper unit is mounted between the center bearing and the mounting bracket and reduces vibration of the propeller shaft.
