To efficiently attenuate sound vibration energy while suppressing as possible, increase of a body weight of a vehicle.SOLUTION: A sound vibration energy attenuation structure has a sound vibration energy transit member (sound vibration energy transit panel 20) for transiting at least some of sound vibration energy which is transmitted on a sound vibration energy transmission member (front side frame 3) from the sound vibration energy transmission member. A length L of the sound vibration energy transmission member in the transmission direction is equal to or more than a half of a wavelength of vibration of the sound vibration energy transmission member, and a fitting part 21 for fitting the sound vibration energy transit member to the sound vibration energy transmission member is provided on a position corresponding to a breast of vibration of the sound vibration energy transmission member.SELECTED DRAWING: Figure 2

    【課題】車体重量の増加を出来る限り抑えつつ、音振エネルギーを効率的に減衰させる。【解決手段】音振エネルギー伝達部材(フロントサイドフレーム3)を伝達する音振エネルギーのうちの少なくとも一部を、該音振エネルギー伝達部材から遷移させる音振エネルギー遷移部材(音振エネルギー遷移パネル20)を備え、上記音振エネルギー伝達部材の上記伝達方向における長さL1は、上記音振エネルギー伝達部材の上記振動の波長の半分以上の長さであり、上記音振エネルギー遷移部材を上記音振エネルギー伝達部材に取り付ける取付部21は、上記音振エネルギー伝達部材の上記振動の腹に対応する位置に設けられている。【選択図】図2
