Abstract
A fixing base for fixing an optical element and disposing at least two elastic members is provided. The fixing base includes a fixing groove and an elastic member fixing groove. The elastic members abut against the elastic member fixing groove to provide the elastic members with a push force toward the optical element, so that the optical element abuts against the fixing groove. An opening direction of the fixing groove and an opening direction of the elastic member fixing groove are nonparallel to the optical axis of the optical element, and the elastic members and the optical element are respectively disposed in the elastic member fixing groove and the fixing groove along a direction nonparallel to the optical axis. The invention also provides a projection device including the fixing base. The fixing base provided by the invention can accurately and easily fix the optical element.
