PROBLEM TO BE SOLVED: To provide a rotary support structure having a simple and light-weight structure, and enabling angular adjustment by a simple operation.SOLUTION: A rotary body 3 includes an eccentric shaft member 10 provided in parallel to a base shaft member 2, a first member 20 supported on the base shaft member 2 and the eccentric shaft member 10, and a second member 30 supported on the eccentric shaft member 10. A support part 21 of the first member 20, and at least one of second abutting parts 32,32 of the second member 30 have a friction engaging surface in a portion abutting on the base shaft member 2. The first support part 21 and the second abutting parts 32,32 sandwich the base shaft member 2 so as to retain a posture to the base shaft member 2 of the rotary body 3. The second member 30 is rotated around a shaft of the eccentric shaft member 10 to the first member 20 so as to adjust a posture to the base shaft member 2 of the rotary body 3.SELECTED DRAWING: Figure 17

    【課題】簡易かつ軽量な構造で、かつ、簡易な操作によって角度調整が可能な回転支持構造を提供する。【解決手段】回転体3は、基軸部材2に平行に設けられた偏心軸部材10と、基軸部材2および偏心軸部材10に支持される第一部材20と、偏心軸部材10に支持される第二部材30とを備える。第一部材20の第一支持部21と第二部材30の第二当接部32,32の少なくとも一方は、基軸部材2に当接する部位に摩擦係合面を有する。第一支持部21と第二当接部32,32とが基軸部材2を挟み込むことにより、回転体3の基軸部材2に対する姿勢が維持される。第二部材30が第一部材20に対して偏心軸部材10の軸まわりに回転されることで、回転体3の基軸部材2に対する姿勢を調整可能となる。【選択図】図17
