To provide a suppression member having a structure in which cross sections cut in a direction orthogonal to one direction are repeated in their sizes, capable of restricting a transmittance of vibration and restricting a plastic deformation at a small cross section part against a load applied from one direction as compared with the case that a proportional limit of a member forming a small cross sectional part is similar to a proportional limit of a member forming a large sectional part.SOLUTION: This invention relates to a restriction member that is formed by applying metallic members extending in one direction of which sectional surfaces cut in a direction crossing at a right angle against one direction to repeat different sizes so as to restrict transmittance of vibration at one direction, and a proportional limit of a member forming a small sectional part of small section is set large as compared with a proportional limit of a member forming a large sectional part having a large section.SELECTED DRAWING: Figure 1
【課題】、一方向に対して直交する方向で切断した断面が大小を繰り返す構造において、小断面部を形成する部材の比例限度が大断面部を形成する部材の比例限度と同様の場合と比して、振動の伝播を抑制した上で、一方向からの荷重に対して小断面部が塑性変形するのを抑制することができる抑制部材を得る。【解決手段】一方向に延びると共に一方向に対して直交する方向で切断した断面が大小を繰り返すように金属部材を用いて形成され、一方向における振動の伝播を抑制する抑制部材であって、断面が小さい小断面部を形成する部材の比例限度は、断面が大きい大断面部を形成する部材の比例限度と比して大きくされている。【選択図】図1
