ABSTRACT:
When a front cover12in which an inner grille13is fitted is mounted to the body of the projector, a fin member13bformed as one unit with the inner grille13is placed with very little clearance between itself and a partition33separating the region where a light source device20is provided from the region where an optical system100is provided. Therefore, hot air of a first fan can be prevented from passing between the partition33and the front cover12and entering the region where the optical system100is provided. As a result, it becomes possible to prevent the hot air from entering the above region and further entering the optical system100or entering the optical path of a projection lens26to cause a heat-wave effect, thus the projector is capable of suppressing a heat-wave effect.
