ABSTRACT:
An objective lens drive apparatus is used in an optical information recording/reproducing apparatus to conduct recording and reproducing of information by radiating a light spot onto a disk recording medium. The objective lens drive apparatus includes an objective lens, an objective lens holding member for holding the objective lens, and a support member for supporting the objective lens holding member movable in a radial direction of the recording medium. In the objective lens drive apparatus, the support member includes a first plate spring fixed to the drive apparatus at one end thereof and extending in a direction perpendicular to a movement direction of the objective lens holding member away from the objective lens holding member, and a second plate spring fixed to a side of the objective lens holding member at one end thereof and extending in the direction perpendicular to the movement direction of the objective lens holding member to be connected to the first plate spring at the other end thereof.
