IMAGE SHAKE CORRECTING DEVICE, LENS BARREL, OPTICAL APPARATUS, AND IMAGE PICKUP APPARATUS

摘要

An image shake correcting device includes a movable unit for holding a correction lens, a rotation preventing plate that rotatably supports the movable unit about a first rotation axis orthogonal to the optical axis, and a fixed base plate that rotatably supports the rotation preventing plate about a second rotation axis orthogonal to the optical axis. The first rotation axis and the second rotation axis intersect at point O on the optical axis of the correction lens. An urging spring urges in a direction where both the movable unit and the fixed base plate are brought closer to each other. A first rolling ball is located on a first hypothetical spherical surface formed between the movable unit and the rotation preventing plate, and a second rolling ball is located on a second hypothetical spherical surface formed between the rotation preventing plate and the fixed base plate.

1. An image shake correcting device that corrects image shake by causing a drive unit to move a movable member for holding a correction member, the image shake correcting device comprising:
a rotation preventing member configured to rotatably support the movable member about a first rotation axis orthogonal to the optical axis of the correction member; and a fixing member configured to rotatably support the rotation preventing member about a second rotation axis which is orthogonal to the optical axis of the correction member and intersects the first rotation axis at a point on the optical axis.
