ABSTRACT:
A lens barrel has its length which is reduced by dispensing with guide rods or a travel mechanism long extending from a base which fixes an image pickup device. The optical axes of multiple lens groups can be easily aligned. An image taking apparatus has its body which has the lens barrel incorporated into it. A second lens group, third lens group and, via the travel mechanism, a fourth lens group are supported by a straight-ahead key ring, and the straight-ahead key ring also supports a front tube holding the first lens group. A zoom motor and a focus motor are also supported by the straight-ahead key ring.
