ABSTRACT:
The supporting structure for a rod integrator300includes, for example, holding members350a, 350bfor holding the rod integrator300, and supporting units360a, 360bfor supporting the holding members. Each holding member350acontacts by its planar portions (walls) respectively with two side surfaces of the rod integrator300adjacent to one another. The holding member350ahas a clearance such that the holding member does not contact with the edge shared by the two side surfaces of the rod integrator300. The supporting unit360aincludes, for example, a supporting member361aand screw362a. The supporting unit360asupports the rod integrator300by pressing of the screw362aalong the direction of the diagonal of the rod integrator300via the supporting member361a. By doing so, chipping and scratching proximate to the edge can be reduced, and soiling of the reflecting plane can be prevented.
