An optical element holding device includes a ring body for accommodating an optical
element and a drive mechanism for driving the optical element. The ring body has
an inner ring portion, which engages with a peripheral edge of the optical element,
and an outer ring portion integral with the inner ring portion. The drive mechanism
includes an actuator, a displacement increasing mechanism and a guide mechanism.
The guide mechanism transfers displacement of the actuator to the inner ring and
moves the inner ring axially.
