<p>PROBLEM TO BE SOLVED: To provide a projector which includes a lens shift mechanism for highly accurately moving a projection lens with a light load.SOLUTION: The projector includes a lens shift mechanism 5. The lens shift mechanism 5 includes: a base part 51 which is fixed to the inside of the projector; a first driving shaft 524 which is supported by the base part 51, to be rotatable around a first center axis 524j extending in a first direction in a plane orthogonal to the optical axis of the projection lens and includes a guide groove on the outer periphery thereof; a moving part 6 which includes an engagement part engaged with the guide groove, supports the projection lens, and is moved in the first direction by the rotation of the first driving shaft 524; a first guide mechanism 53 which includes a rolling member, is supported by the base part 51, and guides the movement in the first direction of the moving part 6; and a tension coil spring 54 which energizes the moving part 6 to a direction along the first direction with respect to the base part 51.</p> |
