Abstract
An optical unit includes a movable body, a fixed body, and a gimbal mechanism. The gimbal mechanism includes a flat plate portion on an opposite subject side with respect to the movable body, two fixed body-side arm portions extending from base end portions to tip end portions in a first intersecting direction, and two movable body-side arm portions extending from base end portions to tip end portions in a second intersecting direction, the fixed body-side arm portions and the movable body-side arm portions are inclined with respect to the flat plate portion as viewed from the intersecting directions, and an inclination direction of the fixed body-side arm portions and an inclination direction of the movable body-side arm portions are opposite to each other as viewed from the intersecting directions.
Claims15
An optical unit comprising:
- a movable body comprising an optical module;
- a fixed body;
- and
- a gimbal mechanism that rotatably supports the movable body with respect to the fixed body around a rotation axis that extends in at least one of intersecting directions intersecting an optical axis direction along an optical axis of the optical module, wherein
- the gimbal mechanism comprises
- a flat plate portion that is provided on an opposite subject side opposite to a subject side of the optical module with respect to the movable body in the optical axis direction,
- two fixed body-side arm portions that extend from base end portions connected to the flat plate portion to tip end portions connected to the fixed body in a first intersecting direction of the intersecting directions, and
- two movable body-side arm portions that extend from base end portions connected to the flat plate portion to tip end portions connected to the movable body in a second intersecting direction of the intersecting directions,
- the fixed body-side arm portions and the movable body-side arm portions are inclined with respect to the flat plate portion as viewed from the intersecting directions, and
- an inclination direction of the fixed body-side arm portions and an inclination direction of the movable body-side arm portions are opposite to each other as viewed from the intersecting directions.
