A lens moving mechanism includes a guide shaft extending in an optical axis direction and a lens frame. The lens frame includes a transfer portion which follows movement of the nut member, which is screw-engaged with a lead screw of a motor. An effective length of the guide shaft is greater than that of the lead screw so that an end of the guide shaft and the motor overlap each other. Part of the fit-on portion of the lens frame is positioned where the end of the guide shaft and the motor overlap each other when the lens frame is at a lens-frame moving end, and is positioned to face the lead screw in a direction orthogonal to the optical axis when the lens frame is at the opposite lens-frame moving end. |
