The pressure is clamped by the two bearing blocks 23 and 24 from above and below in the Y direction, and is positioned substantially at that position. The pressure contact surfaces of the bearing blocks 23 and 24 that are in sliding contact with the hinge balls 22 are formed on concave spherical surfaces 23a and 24a. From behind each of these bearing blocks 23, 24, an arrow 3
A vertical downward force and an upward force are applied by block pressing means represented by 0 and 31. This up-down opposing force is of such a strength that it does not hinder free rotation of the hinge ball 22 in all directions, and that it can be restrained almost at a fixed position.
