ABSTRACT:
According to exemplary embodiments of the present invention, in a projection lens position adjuster, when a part of a dial exposed from an exterior case is rotated downward, a gear is rotated in an R2direction. A Y-slider is then moved downward (in a Y3direction). Accordingly, a Y-table is moved downward, as is a projection lens. When the part of the dial exposed from the exterior case is rotated upward, the projection lens is moved upward. When a part of a dial exposed form the exterior case is rotated leftward as seen from a rear side of a projector, the projection lens is moved leftward. In contrast, when the dial is rotated rightward, the projection lens is moved rightward. Provided around the projection lens are a first light shield for closing a gap between an opening of a front case and a periphery of the projection lens, and a second light shield for closing a gap between the projection lens and a hole of a base of the projection lens position adjuster. A shield body of the first light shield includes a ring-shaped elastic member disposed to extend between a ring and the projection lens, and a pair of attachments extending from the elastic member outward.
