<p>A lens barrel that is small-sized and can be produced at low cost by compactly constructing an inside lens mechanism. In the lens barrel, the number of shafts can be reduced because a guide shaft (61) serves as the common guide shaft. Further, a guide shaft (63) is formed only in a movement region of a zoom movement body (22) and a coil unit (70) is disposed in a space behind the region. Accordingly, the entire lens barrel can be compactly constructed. On the other hand, the guide shaft (61) and a guide shaft (62) are constructed separately, and this results that the length of a sleeve section (21a) of the zoom movement body (22) and the length of a sleeve section (41a) of a focus movement body (42) are sufficient and that a slide length of each movement body is sufficient. As a result, the lens barrel is compact, and accurate and stable operation of each movement body can be realized.</p> |
