[0028] The annular sealing ring 9 is arranged between the base plate pot ring upper surface groove 7-1 and the lower seat plate boss bottom groove 5-1.

[0029] The annular sealing ring 9 and the lower seat plate boss bottom groove 5-1 are in clearance fit, so as to satisfy the adjustment allowance.

[0030] The outer extension part of the lower seat plate 5 forms a lower seat plate boss upper part inclined surface 5-2 at the upper end.
