Abstract
A positioning device for positioning an integration rod module disposed in an optical path between a light source device and a projection lens within a projection apparatus includes a flexible element having a fixing plate section mounted securely on an inner surface of a casing interconnecting the light source device and the projection lens and enclosing the integration rod module, and a first distal plate section extending integrally from one end of the fixing plate section toward a rod cover mounted on the casing for resiliently urging a holder of the rod module to press against the inner surface of the casing at a position opposite to the flexible element. A stop member is disposed securely on the holder adjacent to the rod cover to facilitate abutment of the first distal plate section of the flexible element against the holder to enhance retention of the rod module within the casing.
