ABSTRACT:
In the lens drive unit; the position retaining parts are advanced by rotating the position retaining member, which is held in the case body in such a manner as to become rotatable, in the R direction so that the position retaining parts are positioned just under the protrusion parts of the movable lens body, and eventually the movable lens body can be retained at the middle position. Furthermore, the through-holes are advanced by rotating the position retaining member in the R direction so that the through-holes are positioned just under the protrusion parts of the movable lens body, and eventually the protrusion parts loosely get fitted into the through-holes of the position retaining member to enable the body tube holder to move downward.
