<P>PROBLEM TO BE SOLVED: To provide a lens barrel capable of suppressing scattering of abrasive powder generated from a press-contact part of a linear type vibration actuator, to an optical element. <P>SOLUTION: The lens barrel comprises: a lens holding frame that holds a lens group movable in an optical axis direction; a first guide member that guides the lens holding frame in the optical axis direction; a drive shaft that is extended in the optical axis direction; a slider including a press-contact part that slidably press-contacts the drive shaft in a longitudinal direction of the drive shaft and a coupling part that is coupled to the lens holding frame; a second guide member that guides the slider in the optical axis direction; a vibrator that is provided in either of the drive shaft or the slider; a drive case that holds the drive shaft and the second guide member; and a cover member that covers the press-contact part of the slider by being fixed to the drive case and projects the coupling part to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
