Zusammenfassung:	To provide a technique capable of reducing stress at the time when a load is applied.SOLUTION: A spring comprises a metal bellows part, in which compressive fluid is sealed in a sealed space inside the bellows part. The bellows part comprises a plurality of bent members that are laminated in an axial direction. Each of the plurality of bent members comprises an outside bent part that is bent at the outside end part of the bellows part, and an inside extending part that extends inward and outward of the bellows part inside the outside bent part. The inside extending parts of the bent members adjacent to each other in the axial direction of the bellows part are joined together.SELECTED DRAWING: Figure 1 【課題】荷重が作用したときに応力を緩和することができる技術を提供する。【解決手段】金属のベローズ部を備えており、前記ベローズ部の内側の密閉空間に圧縮性流体が封入されるバネであって、前記ベローズ部は、その軸方向に積層されている複数の湾曲部材を備えており、複数の前記湾曲部材のそれぞれは、前記ベローズ部の外側端部で湾曲している外側湾曲部と、前記外側湾曲部より内側で前記ベローズ部の内外方向に延びている内側延在部と、備えており、前記ベローズ部の軸方向に隣り合っている前記湾曲部材の前記内側延在部同士が接合されている。【選択図】図１
