PROBLEM TO BE SOLVED: To provide a projector, not requiring readjustment by preventing distortion in a curved mirror even when the curved mirror are screwed at two or more portions thereof, and achieving three-dimensional positioning for the curved mirror at one time. SOLUTION: This projector includes: a projection lens from which image light is emitted; and the curved mirror 18 for reflecting the image light emitted from the projection lens toward a screen. The curved mirror 18 has a reflecting surface 17 on one side of a mirror body 25, and a fitting member 30 is mounted to each of mounting lug parts 26 provided on the right and left outsides of the reflecting surface 17. Two fitting members 30 respectively have two projecting parts 34 formed by outward drawing, the projecting parts 34 are fitted to cutout parts 36 formed in a holding frame 19 with a clearance, and in such a state, positioning for the curved mirror 18 is performed by a 6-axis adjusting tool. After positioning, the clearance between the projecting parts 34 and the cutout parts 36 are filled with an adhesive to thereby secure the curved mirror. COPYRIGHT: (C)2011,JPO&INPIT
