Zusammenfassung: | To support a movable body swingably without arranging a plurality of balls between the movable body and a fixed body.SOLUTION: An optical unit 100 with an oscillation correction function for correcting the oscillation of an optical module 11 comprises: a movable body 1 which has the optical module; a frame body 21 which is arranged on the outer side in the radial direction with respect to the movable body in the radial direction; and a plurality of support parts 4 which support the movable body swingably with respect to the frame body. The support part comprises: a guide part 41 which is arranged between the movable body and the frame body to support the movable body; and a pressure application part 42 which presses the guide part toward the movable body. The radial direction inner end part of the pressure application part is connected to the radial direction outer end part of the guide part. The radial direction outer end part of the pressure application part is supported by the frame body. One of the movable body and the guide part has a first convex surface 120 and the other has a first concave surface 410 contacting the first convex surface. The first convex surface and the first concave surface are in the spherical shape.SELECTED DRAWING: Figure 3
【課題】可動体及び固定体間に複数のボールを配置しなくても、可動体を揺動可能に支持する。【解決手段】光学モジュール11の振れを補正する振れ補正機能付き光学ユニット100は、光学モジュールを有する可動体1と、径方向において可動体よりも径方向外方に配置される枠体21と、枠体に対して可動体を揺動可能に支持する複数の支持部4と、を備え、支持部は、可動体と枠体との間に配置されて可動体を支持するガイド部41と、可動体に向かってガイド部を押す与圧部42と、を有し、与圧部の径方向内端部は、ガイド部の径方向外端部に接続され、与圧部の径方向外端部は、枠体に支持され、可動体及びガイド部のうちの一方は第1凸面120を有し、他方は第1凸面に接する第1凹面410を有し、第1凸面及び第1凹面は、球面形状である。【選択図】図3 |
