Summary:PROBLEM TO BE SOLVED: To restrain generation of wind hissing sound caused by exhaust of sealing gas while ensuring sufficient gas sealing function. SOLUTION: Sealing gas is passed forward through a clearance between the outer periphery of a main spindle 20 and the inner periphery of a front wall plate 30. By forming a recessed part 38 at the front wall plate 30, and a shielding plate 40 in front of it, a branched passage for branching from sealing gas passage to the diametrical outside is formed, so that a part of sealing gas is let to go off to another position through the branched passage.
