<P>PROBLEM TO BE SOLVED: To provide a drive unit which is easily assembled while it includes a movable lens. <P>SOLUTION: An imaging unit 1 (drive unit) includes: a lens drive device 20 equipped with a main body part 24 constituted by joining a driving shaft 23, a piezoelectric element 22 driving the driving shaft 23 in an axial direction, and a fixing member 21 supporting one end of the piezoelectric element 22 in this order, and a moving member 25 frictionally engaged with the driving shaft 23 and holding a lens 2 movably in an optical axis direction; and a housing 10 housing the lens drive device 20 therein. The housing 10 includes a piezoelectric element attaching part 11 to which the main body part 24 is attached, and a pair of positive and negative electric contact pieces 12 whose one end is connected to the piezoelectric element 22 by attaching the main body part 24 to the piezoelectric element attaching part 11, and integrally formed in such a state that the electric contact pieces 12 are incorporated in the housing 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
