To provide a buffer device or the like which is suppressed from damaging the appearance in comparison with a case where a cylinder part and an exterior body are welded from the outside by arc welding.SOLUTION: A buffer device is provided with a cylinder part for storing a working fluid and an exterior body into which the cylinder part is inserted in the center line direction of the cylinder part, wherein the exterior body has a cylindrical part to be inserted into which the cylinder part is inserted and a residual part which is a residue excluding the part to be inserted in the center line direction, and the cylinder part and the exterior body are welded by irradiating the exterior body with a beam from the direction in which the cylinder part is positioned at the boundary between the part to be inserted and the residual part.SELECTED DRAWING: Figure 3

    【課題】シリンダ部と外装体とを外側からアーク溶接により溶接した場合と比較して、美観を損なうことを抑制した緩衝装置等を提供する。【解決手段】緩衝装置は、作動流体を収容するシリンダ部と、シリンダ部の中心線方向において、シリンダ部が挿入される外装体と、を備え、外装体は、シリンダ部が内側に挿入される筒状の被挿入部と、中心線方向における、被挿入部を除いた残余である残余部と、を有し、シリンダ部と外装体とは、被挿入部と残余部との境界において、外装体に対してシリンダ部が位置する方向からビームが照射されることで溶接されている。【選択図】図3
