Abstract
A projector including an outer casing, a projection lens and a flexible sealing element is provided. The casing has a first opening. The projection lens is disposed in the casing and has a focusing portion, where the focusing portion is aligned to the first opening. The flexible sealing element is connected to a periphery of the first opening to seal the first opening. The focusing portion is connected to the flexible sealing element. When an external force is exerted to the flexible sealing element, the flexible sealing element is deformed and drives the focusing portion to move, so as to focus the projection lens.
