Zusammenfassung:	Provided is a lens alignment adjustment device capable of suitably correcting an angle accuracy of an optical axis of a lens unit with respect to a projector main body. A lens alignment adjustment device is provided to a projector to retain a projection lens, and is capable of adjusting inclination of an optical axis of the projection lens with respect to the projector. The lens alignment adjustment device includes: a base plate which is retained in a predetermined posture with respect to the projector; and a lens fixing plate to which the projection lens is fixed. The lens fixing plate is rockably coupled to the base plate through intermediation of a first center pin orthogonal to an optical axis of the projection lens. First adjusting means for setting an inclination angle of the lens fixing plate with respect to the base plate about the first center pin is provided.
