Abstract

A stopperincludes a projected portionfor restricting movement of a movable section in a focusing direction and a wall sectionfor restricting movement of the movable section in a tracking direction, the projected portionand the wall sectionbeing integrally formed from a synthetic resin. With the arrangement, a single stoppercan simultaneously restrict the movements of the movable section both in the focusing direction and the tracking direction and determine its movable ranges. Accordingly, unlike conventional arrangements, discrete stoppers for the focusing direction and the tracking direction do not have to be provided, thereby reducing the number of components and cost as well as facilitating mounting operation. In addition, even when a strong impact is applied, the stopper will not be deformed.
