Abstract
A rear project cabinet for arear projection television set in which the screen and the mirror can be easily set in their positions and an optical accuracy can be established. The screen fixing segment and the mirror fixing segment constituting the rear projector cabinet are formed by plastic material in such a manner that each of its depth size and the inclination angle of the mirror may become a set value, thereby a well-focused appropriate screen can be attained by a mere coupling and assembling of these segments, and even in the case that the screen size at the screen fixing segment is different, it can be accommodated by applying a proper insert die during molding of the mirror fixing segment.
