Claims

[Scope of utility model registration request]

A vibrator that is attached to the vehicle body and generates vibrations, an acceleration sensor that detects acceleration caused by vibration and is placed in relation to the position in the vehicle cabin where the vibration should be reduced, and A control means for supplying the vibration signal to the vibration exciter by performing phase shift and gain adjustment based on the engine rotation effect, and performing phase shift and gain adjustment based on the detection signal from the acceleration sensor. - A vehicle body vibration reduction device, characterized in that the control means is stopped so as not to supply the vibration signal to the vibration exciter when the detection signal from the acceleration sensor is equal to or higher than a certain value.
