ABSTRACT:
An objective lens moving apparatus, wherein a pole, which is set upright on a base and supports an objective lens, is fitted with some eccentricity into a hole of a lens holder which holds the objective lens and can be freely turned and slid. The lens holder is elastically supported on the base by an elastic member. In this objective lens moving apparatus, the pole is fitted into the hole of the lens holder opposingly to an elastic force of the elastic member, and the inner face of the hole of the lens holder is always pressed against the pole. Accordingly, the axis of the hole, namely, the optical axis of the objective lens the axis of the pole are always kept almost parallel to each other.
