摘要：
In an objective lens driving device, a movable member shiftable along and rotatable around a vertical shaft is provided for supporting the objective lens to be movable therewith vertically and horizontally. An electromagnetic driving means is provided for driving the movable member as desired. A damper member formed into an annular configuration symmetric around a central axis of a bearing portion provided on the movable member is provided between the movable member and a stationary portion of the device for damping and positioning the movable member for maintaining the objective lens to its neutral position.
