A lens driving device includes a lens holding portion, a driving shaft, a vibration member, and a spring member. The vibration member is connected to one end of the driving shaft and causes the driving shaft to micro-vibrate. The spring member is fixed to the lens holding portion and includes a grip portion that sandwiches and grasps the driving shaft. Extension piece portions that protrude while being bent so as to be separated from the driving shaft are provided at end sides of the grip portion in an axial direction of the driving shaft.

Lens driving device, camera device and electronic apparatus

A lens driving device is described that includes, in an XYZ orthogonal coordinate system, a base, an intermediate member, a movable portion with an attachment portion for attaching a lens body, suspension wires arranged between the base and the intermediate member, and wire-shaped leaf springs arranged between the intermediate member and the movable portion. The suspension wires extend in a Y direction and movably support the intermediate member in an X direction and a Z direction. The wire-shaped leaf springs extend in an X direction and a Z direction and movably support the movable portion in the Y direction. A damper gel is arranged between the leaf spring and the movable portion and the intermediate member, and a damper gel is arranged between the suspension wire and the intermediate member and the base.

A lens driving device includes a first movable lens holding portion that holds a first movable lens body, a second movable lens holding portion that holds a second movable lens body heavier than the first movable lens body, a first driving shaft that drives the first movable lens holding portion and a second driving shaft that drives the second movable lens holding portion, and a first guide shaft and a second guide shaft thicker than the first guide shaft. The first and second guide shafts are arranged in parallel with the first driving shaft and the second driving shaft. Loads of the first movable lens holding portion and the second movable lens holding portion are respectively and independently supported and guided by one of the first and second guide shafts, and rotation is prevented by the other of the first and second guide shafts.

A lens driving device includes a carrier with an attachment portion for attaching a lens body and a base comprising a resin main body and a metal plate member embedded in the resin main body and movably supporting the carrier. An opening portion is provided in a center of the resin main body and the metal plate member is provided so as to block the opening portion. In the opening portion, the carrier directly opposes to the metal plate member.

A camera device includes: a lens carrier that holds a lens body; and a blade driving device that drives a blade arranged on a front side of the lens body, wherein the lens carrier has a metallic carrier side receiving portion extending forward from a front end of the lens carrier, the blade driving device has a metallic blade side receiving portion protruding sideward or rearward from a side surface or a bottom surface of the blade driving device, and the carrier side receiving portion and the blade side receiving portion are fixed and electrically connected.

Camera device and electronic apparatus

A lens driving device is describes that includes a stator and a mover, with a lens support for supporting the lens and for moving in an optical axis direction of the lens with respect to the stator. Any one of the stator and the mover has protruding portions and any other one of the stator and the mover has recessed portions into which the protruding portions are inserted. The protruding portions and the recessed portions each have opposing surfaces where the protruding portions and the recessed portions are opposed to each other, and a resin with viscoelasticity is provided to contact the opposing surfaces of the protruding portions and the opposing surfaces of the recessed portions.
