    摘要: An image projection apparatus includes: a light source (160); an exhaust fan (7) configured to discharge air in the apparatus to outside of the apparatus; and a plurality of wind guiding walls (82a, 82b, 82c, and 82d) extending in a direction perpendicular to an exhaust direction of the exhaust fan (7), and configured to guide air that has cooled the light source (160). The wind guiding walls (82a, 82b, 82c, and 82d) are arranged side by side in a rotation axis direction of the exhaust fan (7). At least a downstream portion of each of the wind guiding walls (82a, 82b, 82c, and 82d) in an air flowing direction after cooling the light source (160), is gradually inclined so as to move away from the exhaust fan (7) in the rotation axis direction of the exhaust fan (7), toward downstream in the air flowing direction.
