<p>A lens unit, despite its having a lens drive device that drives a lens and a light path restriction device that restricts a light path, providing stable lens drive and reduced in size. The lens unit (1) includes a lens frame (4) for holding the lens (3); the lens drive device (9) for moving the lens frame (4) along an optical axis (x); and the light path restriction device (5) having light path restriction/drive sections (11, 12) fixed to the lens frame (4) and individually driving the light path restriction members (18, 19, 20). The light path restriction/drive sections (11, 12) are arranged spaced from each other, and the lens drive device (9) is placed penetrating between the light path restriction/drive sections (11, 12).</p> |
