A lens device includes a first moving member configured to hold an optical element and move in an optical axis direction, a first shaft member configured to engage with a first guide portion of the first moving member and configured to guide a movement of the first moving member in the optical axis direction, a base member configured to hold one end portion of the first shaft member, and a holding member configured to hold the other end portion of the first shaft member, wherein the base member is provided with an object side restriction end and an image side restriction end, the object side restriction end being configured to restrict the movement of the first moving member in a direction toward an object side, the image side restriction end being configured to restrict the movement of the first moving member in a direction toward an image side.

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.

A photosensitive element driving mechanism is provided and includes a fixed assembly, a first movable assembly, a photosensitive element and a first driving assembly. The fixed assembly has a base plate. The first movable assembly includes a circuit member movable relative to the fixed assembly, and the circuit member includes a circuit member body and a movable cantilever. The photosensitive element is configured to receive light traveling along an optical axis. The photosensitive element is disposed on the circuit member body and is electrically connected to the circuit member. The first driving assembly is configured to drive the first movable assembly to move relative to the fixed assembly. There is a gap between the first movable assembly and the fixed assembly, and only the photosensitive element is disposed on the circuit member body.

Embodiments relate to a camera actuator and a camera module including same. The camera actuator according to an embodiment comprises a lens unit, a shaper unit, a first driver coupled to the shaper unit, and a second driver arranged to correspond to the first driver.
