<p><P>PROBLEM TO BE SOLVED: To allow firm fixing of a color filter to a driving motor to improve workability in assembly. <P>SOLUTION: A color wheel equipped in an optical engine of this invention includes a color filter with many different colors divided on the circumference thereof, a driving motor providing a driving source to rotate a rotor with the color filter assembled thereinto about a rotational axis in parallel with an optical axis, a carrier assembled into the rotor, a filter adhesion layer providing adhesive force for fixing the color filter to the carrier by an adhesive applied on an adhesion area where the color filter is superposed and a holder having a fixing part in an inner surface thereof corresponding to an outer surface of the rotor in order to maintain an application state of compressive force owing to a predetermined intensity of external force applied to the filter adhesion layer through the color filter, thereby imparting a compressive stress which offsets a tensile stress generated at the filter adhesion layer to the filter adhesion layer. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
