摘要： A projector includes a sirocco fan 762 as an exhaust fan arranged oppositely to an exhaust hole 2B formed on an exterior case 2 to suck air inside the exterior case 2 and to discharge the air to the outside via the exhaust hole 2B. The sirocco fan 762 is arranged such that a suction side thereof is along a plane orthogonal to an optical path plane defined by a light source device, an optical modulator and a projection optical device of a device body of the projector. Further, the sirocco fan 762 is arranged such that a discharge hole 762A is inclined in a fan rotation direction to discharge the sucked air substantially to the center of an end surface with the exhaust hole 2B formed in a thickness direction. Accordingly, such projector is provided that can enhance an exhaust efficiency by sucking the air of the inside effectively without the rotation number of the exhaust fan increased, and also can reduce the thickness thereof.
