To reduce propagation of noise in a pipe in a wide frequency range at a skeleton member 1 of a vehicle.SOLUTION: Helmholtz type resonators 11 are cyclically provided at intervals in a longitudinal direction of a skeleton member 1 within the skeleton member 1. Cavities 12 of the respective resonators 11 open at intervals in the longitudinal direction in a hollow space 13 extending in the longitudinal direction within the skeleton member 1.SELECTED DRAWING: Figure 2

    【課題】車両の骨格部材1における騒音の管内伝播を広い周波数範囲で低減させる。【解決手段】複数のヘルムホルツ型共鳴器11を骨格部材1の内部に骨格部材1の長手方向に間隔をおいて周期的に設け、共鳴器11各々のキャビティ12を骨格部材1の内部を長手方向に延びる空洞部13に該長手方向に間隔をおいて開口させる。【選択図】図2
