Claims

[Scope of Claim for Utility Model Registration] (1) In a support device for an exhaust system component that suspends the exhaust system component on a vehicle body via an elastic support member, a frequency detection means provided on the exhaust system component; A vibrator provided between a vibrator and a vehicle body; When the natural frequency of the vehicle body and the frequency of the forced vibration mode are determined to be the same by the number matching determination means, this signal is received, and the vibration mode with the same frequency as the forced vibration mode of the exhaust system parts is detected. an oscillation circuit that generates a voltage or current and sends it to the vibrator; and a waveform setting means that sets the vibration mode of the voltage or current generated by the oscillation circuit to be in opposite phase to the forced vibration mode of the exhaust system components. A support device for exhaust system parts, characterized by comprising: (2) In a support device for exhaust system components that suspends the exhaust system components on the vehicle body via an elastic support member, a vibration frequency detection means provided on the exhaust system component and a frequency detection means provided between the elastic support member and the vehicle body. Whether the frequency of the forced vibration mode detected by the vibrator, the oscillation circuit that generates voltage or current that causes the vibration mode of the vibrator, and the frequency detection means is the same as the natural frequency of the vehicle body. When the natural frequency of the vehicle body and the frequency of the forced vibration mode are determined to be the same by the frequency match determining means and the frequency match determining means for determining whether or not the natural frequency of the vehicle body is the same, the oscillation circuit Frequency setting that sets the frequency of the vibration mode of the vibrating vibrator so that the frequency of the combined vibration of the vibration mode of the vibrator and the forced vibration mode of the exhaust system components deviates from the natural frequency of the vehicle body. 1. A support device for exhaust system components, comprising: means.
