There is provided a projection lens that is mounted on a housing of a projection device including an electro-optical element. The projection lens comprises an optical system through which light passes, a second holding unit through which light parallel to a second optical axis passes and which is moved rotationally with respect to the housing, a third holding unit through which light parallel to a third optical axis obtained from bending of the second optical axis passes and which is moved rotationally with respect to the second holding unit, an electric drive unit that electrically controls rotational movement of the second holding unit with respect to the housing, rotational movement of the third holding unit with respect to the second holding unit, or drive of the optical system, and a cover part that covers the electric drive unit.
