Abstract
When a front coverin which an inner grilleis fitted is mounted to the body of the projector, a fin memberformed as one unit with the inner grilleis placed with very little clearance between itself and a partitionseparating the region where a light source deviceis provided from the region where an optical systemis provided. Therefore, hot air of a first fan can be prevented from passing between the partitionand the front coverand entering the region where the optical systemis provided. As a result, it becomes possible to prevent the hot air from entering the above region and further entering the optical systemor entering the optical path of a projection lensto cause a heat-wave effect, thus the projector is capable of suppressing a heat-wave effect.
