Noise vibration energy damping structure in vehicle

A noise vibration energy damping structure in a vehicle, the noise vibration energy damping structure damping noise vibration energy that is generated at a power unit of the vehicle comprised of an engine and a transmission and that is to be transmitted to a cabin of the vehicle, the noise vibration energy damping structure comprising:

• a vibration energy path member, to which a supporting device supporting the power unit is attached, constituting a transmission path which vibrates by receiving the noise vibration energy transmitted through the supporting device, and which transmits the noise vibration energy to the cabin;
• and
• a vibration energy damping member provided on the transmission path of the vibration energy path member, and absorbing, from the vibration energy path member, at least part of the noise vibration energy to be transmitted from the vibration energy path member to the cabin, wherein
• the vibration energy damping member is disposed substantially along a transmission direction in which vibration of the vibration energy path member caused by the noise vibration energy is transmitted,
• a length of the vibration energy damping member is equal to or more than a half of a wavelength of the vibration of the vibration energy path member, and
• the vibration energy path member is provided with at least one attachment part attaching the vibration energy damping member to the vibration energy path member, and the at least one attachment part is disposed in a position corresponding to a position of at least one antinode of the vibration of the vibration energy path member.
