OPTICAL-ELEMENT HOLDING MECHANISM, IMAGE-SHAKE CORRECTING DEVICE AND OPTICAL APPARATUS

摘要

An optical-element holding mechanism includes a first holding member arranged to hold a first optical element, a second holding member arranged to hold a second optical element, a coupling member arranged to couple the first and second holding members with each other and to permit relative positions of the first and second holding members to be varied in process of being coupled, and an urging member disposed between the coupling member and the second holding member and arranged to urge and press the second holding member against the first holding member at least when the coupling member is in process of coupling the first and second holding members. Further, an image-shake correcting device mounted on an optical apparatus includes a body member, and a lens unit arranged to be moved with respect to the body member in a direction orthogonally intersecting an optical axis for correcting an image shake, wherein the body member is provided with a recessed part formed in a periphery thereof to insert therein a member which extends before and after the body member in a direction of an optical axis and which constitutes the optical apparatus.
