ABSTRACT:
When an attempt to move a projection lens in a horizontal direction (crosswise) in a state where it is positioned on the upper or lower side is made, it can be moved in the horizontal direction (crosswise) up to a certain range. However, a movement restraining convex area in a vertical movable base finally comes into contact with the corner inclined at an angle of 45 degrees in a fixed base. After this contact, movement in a leftward or rightward direction and an upward or downward direction which are limited directions is limited. Even if a dial and a dial are rotated in the limited directions under the limitation of the movement, they are slipped, thereby making it possible to prevent a force from being forcedly applied to a driving mechanism.
