An image projector includes a first deflector configured to deflect a first optical path and to form a second optical path, a second deflector configured to deflect the second optical path and to form a third optical path, a shifter configured to shift a projection lens in a vertical direction which corresponds to a longitudinal direction of the projected surface among directions orthogonal to an optical axis of the projection lens, a housing configured to house the first deflector and the second deflector, and a fixed plate fixed onto the housing at an end on an installing surface side of the housing, the projection lens and the shifter being fixed onto the fixed plate, wherein the third optical path is closer to an installing surface of the housing than the first optical path. |

1. An image projector comprising:
an image display element configured to display an original image; a first deflector configured to deflect a first optical path through which light from a light source passes, and to form a second optical path; a second deflector configured to deflect the second optical path and to form a third optical path; a shifter configured to shift a projection lens in a vertical direction, which is orthogonal to an optical axis of the projection lens, the projection lens projecting light that has transmitted the image display element, the first deflector, and the second deflector; a housing configured to house the image display element, the first deflector, and the second deflector, and having an installing surface, which is one of a top surface or a bottom surface, that is closer to the third optical path than the first optical path; and a fixture member configured to integrally fix the projection lens, the shifter, the first deflector, and the second deflector, the fixture member being fixed onto the housing at on an installing surface side of the housing, wherein the shifter is configured so that, in relation to the third optical path, a shiftable amount of the projection lens in a direction away from the installing surface side is larger than a shiftable amount of the projection lens toward the installing surface side. |
