To suppress generation of buckling during compression of a bellows.SOLUTION: A bellows is a synthetic resin bellows, and comprises: a crest part that is convex in a radial direction; a trough part adjacent to the peak part in an axial length direction, and concave in the radial direction; and an intermediate part including a midpoint in the radial direction of the apex of the external surface of the crest part and the apex of the external surface of the trough part. A first length, which is a length in the axial length direction between the apex of the external surface of the peak part and the midpoint, is larger than a second length, which is a length in the axial length direction between the apex of the external surface of the trough part and the midpoint.SELECTED DRAWING: Figure 2 【課題】ベローズの圧縮時の座屈の発生を抑制する。【解決手段】ベローズは、合成樹脂製のベローズであって、径方向において凸状の山部と、前記山部と軸長方向に隣り合い、前記径方向において凹状の谷部と、前記山部の外表面の頂点及び前記谷部の外表面の頂点の前記径方向における中点を含む中間部と、を備え、前記山部の外表面の頂点と前記中点との間の前記軸長方向における長さである第１長さが、前記谷部の外表面の頂点と前記中点との間の前記軸長方向における長さである第２長さよりも大きい。【選択図】図２
