Abstract
A video-displaying apparatus uses a rod integrator that converts light emitted from a light source into uniform light. The apparatus includes a rod integrator, a holding member, and a flat spring. The rod integrator has a first surface, a second surface that opposes the first surface, a third surface, and a fourth surface that opposes the third surface. The holding member has a first contact surface which abuts the second surface, and a second contact surface which abuts the fourth surface. The first and second contact surfaces have smaller areas than the second and fourth surfaces, respectively. The rod integrator is fixedly mounted to the holding member such that the rod integrator is sandwiched between the holding member and the flat spring mounted to the holding member. Only the projections formed in the spring abut the first and third surfaces.
