1. A projector that modulates, according to image information, a luminous flux emitted from a light source, and projects the modulated luminous flux through a projection lens, comprising:
an external housing that accommodates the light source and the projection lens, and includes a projection opening through which the luminous flux projected through the projection lens passes, and an exhaust port arranged on the same side as the projection opening and through which inside air is discharged to an outside; an axial-flow fan that includes a rotating shaft and blades arranged around the rotating shaft, causes air to flow therein in a direction of a central axis of the rotating shaft with the rotation of the blades, and delivers the air flowing therein; and a plurality of slats that are arranged at the exhaust port to extend in a direction intersecting a first direction in which the projection opening and the exhaust port are arranged, and guide the air delivered from the axial-flow fan to the outside, wherein the plurality of slats include an elongated slat that is disposed in, among four exhaust areas arranged side by side in the first direction in the exhaust port and a second direction orthogonal to the first direction, one of the two exhaust areas on the side close to the projection opening and whose length in a direction in which the air delivered from the axial-flow fan is guided to the outside so as to correspond to a rotational direction of the blade is longer than that of the slats disposed in the other areas. |
