<P>PROBLEM TO BE SOLVED: To carry out easily slidable bearing height adjusting work. <P>SOLUTION: Roll bearings 16 and 17 are interposed between a support shaft 14 and a spindle 15. To the upper end of the spindle 15, a horizontal disk-like table 31 is attached with its lower face peripheral edge set facing a guide face 13. A screw hole 42 is formed at the outer peripheral surface of the table 31. A ring-shaped height adjusting member 43 is fitted to the outer peripheral surface of the table 31 so as to cover it where the ring-shaped height adjusting member moves up and down freely and covers the screw hole 42. The height adjusting member 43 has a bolt hole 44 formed to match the screw hole 42. A bolt 45 is loose-fitted into the bolt hole 44 and screwed into the screw hole 42. To the height adjusting member 43, a slidable bearing 46 is fixed in such a way that a slide surface 47 thereof faces the guide face 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
