PROBLEM TO BE SOLVED: To provide a telescopic beam that can suppress a deflection amount of a cylinder tube even if a cylinder device having pin-joined mounting parts is installed in a posture along extending/contracting directions, and a fixing member of the cylinder device in the telescopic beam.SOLUTION: A telescopic beam comprises a cylinder device 6, a beam body 40, and a fixing member 7. In the cylinder device 6, mounting parts 62 are provided in one end part in a longer direction of a cylinder tube 61. The mounting part 62 has a shaft hole 68. The beam body 40 is constituted to extend/contract by the cylinder device 6. The fixing member 7 has a body part 71 which is pin-joined with the mounting parts 62 and fixed to the beam body 40, and a rotation-regulating part 76 which regulates upward movement of a tip part of the mounting parts 62 about a connection pin.SELECTED DRAWING: Figure 4
【課題】ピン接合される取付部を有するシリンダ装置を伸縮方向に沿った姿勢で取り付けても、シリンダチューブのたわみ量を抑制できる伸縮ビーム、および伸縮ビームにおけるシリンダ装置の固定部材を提供する。【解決手段】伸縮ビームは、シリンダ装置6と、ビーム本体40と、固定部材7とを備える。シリンダ装置6は、シリンダチューブ61の長手方向の一方の端部に取付部62が設けられる。この取付部62は軸孔68を有する。ビーム本体40は、シリンダ装置6により伸縮するように構成される。固定部材7は、取付部62とピン接合されると共にビーム本体40に固定される本体部71と、取付部62の先端部が、接続ピン回りにおいて上方へ移動するのを規制する回転規制部76とを有している。【選択図】図4
