Abstract
A projector is provided in which the production of an outer casing is facilitated, cooling efficiency is maintained well, and the outward appearance is preferable. A dustproof ventilating member is mounted in a clearance formed between the rim of an opening of a front casing forming an outer casing, and a projection lens. For this reason, cooling air can be reliably drawn into a device via the ventilating member. Since this eliminates the necessity for forming a meshed air inlet in the outer casing, the production of the outer casing is facilitated, and the manufacturing operation of the projector is easily performed. Moreover, cooling efficiency is maintained well, and the outward appearance is made preferable.
