ROTATING BODY SUPPORT SHAFT

PROBLEM TO BE SOLVED: To provide a rotating body support shaft which is constituted so as to be capable of attaching a rotating body so that a rotation axial direction of the rotating body accurately coincides with a proper direction, and capable of adjusting a position of the attached rotating body.SOLUTION: A rotating body support shaft 1 comprises a first end part 10 and a second end part 20 which are separately arranged, and a shaft part 30 which is formed long in a length, connected to the first end part 10 at one end, connected to the second end part 20 at the other end, and has a plurality of elastic rod-shaped members 31 which are aligned so as to surround an axial line L for connecting the first end part 10 and the second end part 20. Then, the shaft part 30 is elastically deformable to a direction orthogonal to the axial line by elastic forces of the plurality of the elastic rod-shaped members 31, and the plurality of the elastic rod-shaped members 31 possessed by the shaft part 30 have extension parts 313 which are radially extended when viewed from an axial direction of the axial line L within a reference plane P which is vertical to the axial direction of the axial line L.SELECTED DRAWING: Figure 1 【課題】 回転体の回転軸方向が精度よく適正方向に一致するように回転体を取り付けることができ、且つ、取り付けられた回転体の位置を調整することができるように構成された回転体支持シャフトを提供すること【解決手段】 回転体支持シャフト１は、離間して配設された第一端部１０及び第二端部２０と、長尺状に形成されるとともに一方端にて第一端部１０に接続され他方端にて第二端部２０に接続され、第一端部１０と第二端部２０とを結ぶ軸線Ｌを囲むように配列された複数の弾性棒状部材３１を有する軸部３０と、を備える。そして、軸部３０は、複数の弾性棒状部材３１の弾性力によって軸線に直交する方向に弾性変形可能であり、さらに、軸部３０が有する複数の弾性棒状部材３１は、軸線Ｌの軸方向に垂直な基準平面Ｐ内にて軸線Ｌの軸方向から見て放射方向に延設される延設部３１３を有する。【選択図】 図１
