Abstract: A projection image display apparatus has a front panel, a projection lens, a lens hood, and a lens dial. The front panel has an opening for the projection lens. The projection lens projects through the opening for the projection lens. The lens hood covers the projection lens circumferentially, and has an opening spaced from an end of the lens hood for a dial. The lens dial is provided for adjusting focusing or zooming. It is provided at a circumference of the projection lens and exposed through the opening for the dial. The apparatus can thus avoid dust or the like foreign matters otherwise entering from a top side thereof into its main body, and also protect the projection lens when the apparatus is carried and inadvertently has a projection lens unit brought into contact with a desk or the like.
