ABSTRACT:
A projection position adjuster (8) of a projector includes a fixing plate (81), a first moving plate (82) that can move in a Y-axis direction and an X-axis direction orthogonal to each other in a plane orthogonal to a projection direction, a first adjusting driver (86) that moves the first moving plate (82) in the Y-axis direction, a second moving plate (83) that can move in the X-axis direction and moves the first moving plate (82) in the X-axis direction by engaging with the first moving plate (82), and a second adjusting driver (87) that moves the second moving plate (83) in the X-axis direction. The first moving plate (82) and the second moving plate (83) are superposed onto the fixing plate (81) in a projection direction. The first moving plate (82) is movably abutted on the fixing plate (81) and supports and fixes the projection lens (3).
