Abstract
The present invention facilitates with high accuracy the adjustment of a minute angle degree, and also is capable of sufficiently securing the rigidity of the whole device after the adjustment and provides good operability, accuracy, and rigidity. Provided are a workpiece attaching body having a workpiece attaching surface and a rotating body rotatably supporting the workpiece attaching body. The rotating body has an inclination angle adjusting surface inclined relative to an axis of the rotating body, the workpiece attaching body has opposite to the workpiece attaching surface an inclination angle adjusting surface which is inclined relative to the workpiece attaching surface and which comes in surface contact with the inclination angle adjusting surface of the rotating body, and spherical coupling means is arranged which is for rotatably adjustably coupling the workpiece attaching body and the rotating body about a spherical center on an axis of the rotating body along both inclination angle adjusting surfaces. Thereby, the rotating body and the workpiece attaching body are relatively rotated about the spherical center along both inclination angle adjusting surfaces so as to adjust the inclination angle of the workpiece attaching surface.
