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) a spherical surface and a columnar projection protruding in a radial direction from the spherical surface are provided on the outer periphery of the screw mounting, and (b) Assuming a spherical seat having a concave spherical surface corresponding to the above-mentioned spherical surface, a pair of split spherical seats each having a shape divided in half by a plane passing through the center of the above-mentioned spherical seat are constructed; (c) Each of the above-mentioned split spherical seats about,
(d) On the other hand, the movable body is provided with a hole having a larger diameter than the outer shape of the spherical seat, and the spherical surface A seat is disposed in the hole, and (e) an elastic member is interposed between the inner wall surface of the hole and the spherical seat to elastically support the spherical seat. Axial adjustment device.
