PURPOSE:To reduce a cost by providing a moving member moving together with a lens, and an elastic member provided on one of this moving member side or a fixed member side, and positioning a lens barrel irrespective of a driving force of a motor. CONSTITUTION:An optical device is provided with a lens barrel 21b being a moving member moving together with a lens, and plate springs 22, 22' provided on one of this lens barrel 21b side or an outer cylinder 23 side being a fixed member. Also, these plate springs 22, 22' are formed roughly in a V-shape, and when they are engaged with plate spring engaging holes 23a, 23'a or 23b, 23'b of the outer cylinder 23, they move and position an arm 21 and the lens barrel 21b to a prescribed position from directly before the prescribed position irrespective of a turning force of a turning pin 18b, respectively. In this way, positioning of the lens barrel can be executed irrespective of a driving force of a motor, and a manufacturing cost can be reduced. |
