PROBLEM TO BE SOLVED: To suppress excitation vibration that may be excited in a folding elastic deformation part, when some vibration occurs during operation of a rotating device, while simplifying the manufacturing proces, and to enhance stability of rotating operation.SOLUTION: In a rotating device including folding elastic deformation parts 12-15 having a folding structure composed of a single member, a support 11 for supporting one end of the folding elastic deformation parts, a movable part 17 attached to the other end side of the folding elastic deformation parts, and drive means 20-23 for rotating the movable part repeatedly around a predetermined rotating shaft, by imparting a driving force for deforming the folding elastic deformation parts, where a coupling part 33 for coupling a part of the forward parts 12, 14 and a part of returning parts 13, 15 adjacent thereto is provided in the folding elastic deformation parts, the coupling part is composed of the single member and has a structure integral with the folding structure.SELECTED DRAWING: Figure 4

    【課題】製造工程を簡略化しつつ、回動装置の動作中に何らかの振動が発生したときに折り返し弾性変形部に励起され得る励起振動を抑制でき、かつ、回動動作の安定性を向上させることを課題とする。【解決手段】単一部材から構成される折り返し構造を有する折り返し弾性変形部12〜15と、前記折り返し弾性変形部の一端を支持する支持部11と、前記折り返し弾性変形部の他端側に取り付けられる可動部17と、前記折り返し弾性変形部を変形させる駆動力を付与して前記可動部を所定の回動軸回りで繰り返し回動させる駆動手段20〜23とを有し、前記折り返し弾性変形部に、前記折り返し構造における往路部分12,14の一部分とこれに隣り合う復路部分13,15の一部分とを連結する連結部分33が設けられた回動装置において、前記連結部分は、前記単一部材から構成され、前記折り返し構造と一体構造となっている。【選択図】図4
