A lens barrel includes a first optical element that is allowed to move
along an optical axis, a first driven member connected to the first
optical element, a second optical element disposed in the optical axis of
the first optical element, which is allowed to move along the optical
axis, a second driven member connected to the second optical element, a
first drive shaft disposed substantially parallel to the optical axis to
drive the first driven member along the optical axis, a second drive
shaft disposed substantially parallel to the optical axis to drive the
second driven member along the optical axis, a first drive unit connected
to an end of the first drive shaft to drive the first drive shaft, and a
second drive unit connected to an end of the second drive shaft to drive
the second drive shaft and disposed at a position that partially overlaps
a position of the first drive unit when viewed from the direction of the
optical axis.
