The objective of the present invention is to provide a vehicle vibration and noise reduction system that can improve rideability of motor vehicles and/or riding comfort level, while minimizing vibration noises generated in the passenger compartment of the vehicle. The vehicle vibration and noise reduction device has a loudspeaker (32) which can eliminate the noise. An adaptive filter (56) generates the optimal canceling sound based on an error signal detected by a microphone (33) which detects the noise in the passenger compartment of the vehicle. A variable elastic member (4) is incorporated in a vibration transmission path from a road to the passenger compartment of the vehicle. The coefficient from the adaptive filt (56) is made to be optimal in consideraton of the vibration and strain detected by a strain sensor (31) provided on a variable elastic member.
