Abstract
There are provided a lens guide device, a lens moving device, and an imaging apparatus that can accurately position a lens frame regardless of an attitude, such as an imaging direction. A first-rail supports a first-rolling-body so as to allow the first-rolling-body to be rollable in a first-direction parallel to an optical-axis of a first-focus-lens. A second-rail supports a second-rolling-body so as to allow the second-rolling-body to be rollable in the first-direction. A biasing-mechanism supports the first-rolling-body so as to allow the first-rolling-body to be movable in the first-direction, and biases the first-rolling-body toward the first-rail. A third-rail is provided in parallel with the second-rail. The third-rail supports the second-rolling-body so as to allow the second-rolling-body to be movable in the first-direction. Since the first-rail and the second-rail are moved and guided in a first direction by the first-rolling-body and the second-rolling-body, a lens frame is not inclined.
