Abstract
To provide a projector in which the position of a handle can be reliably maintained even when a housing and the handle are made of different materials. In a projector, the position of a handle is maintained with projections formed in the handle and contact portions of a lower casing being in contact with each other, and both the projections and the contact portions may be made of a same kind of material, such as resin. Therefore, there is no fear that one of the projections and the contact portions will undergo localized wear. Even when the lower casing is made of metal and the handle is made of resin, the handle can sufficiently withstand repetitive operations, and the position thereof can be reliably maintained.

A handle opening is formed by cutting a part of an exterior case, a rising portion is formed by bending the case toward inside of a casing along cutting periphery of the handle opening, a shaft member for rotatably supporting the handle is inserted to an attachment hole formed on the rising portion, and a screening member for covering the handle opening from the inside of the casing is engaged to the rising portion, thereby covering the gap between the handle and the rising portion by the screening member to improve appearance after attaching the handle.
