PROBLEM TO BE SOLVED: To provide a suspension structure for supporting a surgical microscope that enables a plurality of rotation shafts to be brought into a lock/free state simultaneously with a mechanical structure.SOLUTION: First lock means 7 and second lock means 8 that can stop the rotation of a first rotation shaft 4 and a second rotation shaft 5 simultaneously by being brought into mechanical contact with the first rotation shaft 4 and the second rotation shaft 5 by the same transmission power are provided to a lateral surface part 10, and a vertical surface part 11 that support the first rotation shaft 4 and the second rotation shaft 5 so that lock/free of the first rotation shaft 4 and the second rotation shaft 5 can be performed mechanically.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】機械的構造で複数の回転軸を同時にロック／フリー状態にできる手術顕微鏡支持用吊下構造を提供する。【解決手段】第１回転軸４、第２回転軸５を支持する横面部１０、縦面部１１に、それぞれ同一の伝達動力により第１回転軸４、第２回転軸５と機械的に接触して第１回転軸４、第２回転軸５の回転を同時に停止自在な第１ロック手段７、第２ロック手段８が設けられているため、第１回転軸４、第２回転軸５のロック／フリーを機械的に行うことができる。【選択図】図１
