ンズ駆動装置。[Claims for Utility Model Registration] A pair of first plate springs capable of displacing the objective lens barrel including the objective lens or its support member in either the optical axis direction of the objective lens or a direction perpendicular thereto. A pair of first and second lenses are connected to the intermediate support member via the intermediate support member so as to drive the objective lens barrel in the one direction, and are capable of displacing the intermediate support member in a second direction orthogonal to the one direction. 2
An objective lens drive device that is connected to a fixed member via a leaf spring and drives an intermediate support member in a second direction, the leaf spring and a rubber-like elastic body for absorbing vibrations of the leaf spring. and a presser member for fixing the leaf spring are integrally molded.
