ABSTRACT:
An objective lens drive device that can be assembled with a high production efficiency, without any adhesives being forced out. The objective lens drive device is in the form of a bi-axial actuator having empty chambers 25a, 25b formed by a portion of a bobbin holder 15, a portion of a lens holder 2, and a portion of a coil bobbin 4. The empty chambers 25a, 25b are filled with an adhesive 3 to bond the coil bobbin 4 to the lens holder 2. Thus, no adhesives are forced out, and the adhesive can be cured within a short time.
