Image projection apparatus

An image projection apparatus, comprising:

• a light source configured to irradiate light to project a projection image;
• a holder configured to support the light source, the holder having an exhaust duct for exhausting air heated by the light source;
• an exhaust fan having a rotary shaft provided with at least one blade, the rotary shaft being rotated to exhaust air inside the image projection apparatus to the outside of the image projection apparatus;
• and
• a guide configured to guide air exhausted from the exhaust duct and air that is not exhausted from the exhaust duct toward the rotary shaft of the exhaust fan, the guide having a sloped face that is sloped upward to the exhaust fan so that the air exhausted from the exhaust duct is guided by the guide while ascending as ascending airflow, the sloped face having a first side surface facing the light source and a second side surface that is a back surface of the first side surface, the first side surface defining a first flow path to guide air heated by the light source toward the rotary shaft of the exhaust fan, the second side surface defining a second flow path to guide air having temperature lower than temperature of the air heated by the light source toward the rotary shaft of the exhaust fan, wherein the second flow path is made narrower at an exhaust section from which the air is exhausted than at an intake section from which the air is taken.
