PROBLEM TO BE SOLVED: To avoid a focusing error and a tracking error by improving transmission characteristics in an object lens driving device regardless of a difference in posture and improving vibration resistance against vibration caused by external factors and internal factors. SOLUTION: In the object lens driving device 1 which moves an object lens 5 in the focusing direction and the tracking direction relative to an optical disk, a base member 2 in which a spindle 3 is provided, a turning body 4 which is supported by the spindle 3 so as to freely turn around the spindle 3 and freely move in the axial direction and by which the object lens 5 is held, a focusing driving part 6 which drives the turning body 4 in the axial direction and a tracking driving part 7 which drives the turning body 4 in the turning direction are provided. The turning body 4 is composed of a lens holder part 9 which holds the object lens 5 and a boss part 8 which is supported by the spindle 3, and the lens holder part 9 is combined to the boss part 8 via a buffer member 16.
