Claims

[Scope of Claim for Utility Model Registration] A ball support mechanism in which a movable body is rotatably and tiltably supported on a fixed body, a screw mounting attached to the movable body, and a screw mounted on the screw mounting, and the fixing device. In an optical axis adjustment device equipped with an adjustment screw worn on the body, (a) the screw mounting is configured in the shape of a spherical nut, and (b) a screw is attached to the spherical surface portion of the outer periphery of the screw mounting. (c) the movable body is provided with a spherical seat corresponding to the ball nut-shaped screw mounting and a groove-like recess that fits into the projection; d) An optical axis adjustment device characterized in that a spring means is provided for applying a rotational force to the movable body in a direction to bring the spherical seat into close contact with the spherical screw nut.
