Abstract

PURPOSE: To properly reduce noise and vibration by forming the air intake part and the air discharge part which communicates to the air intake part and is opened into the negative pressure space in a casing, on a rotary main shaft.
CONSTITUTION: The air intake part 19 which communicates to the atomosphere and the air discharge part 18 which communicates to the air intake part 19 and is opened, on the rotary peripheral surface of a rotary main shaft 12, into the negative pressure space in a casing 14 are formed on the rotary main shaft 12. Therefore, if a negative pressure is formed in the casing 14, the air inhaled from the air intake part 19 is discharged from the air discharge part 18, and an air bubble layer is formed between the rotary peripheral surface of the rotary main shaft 12 and the jet stream in contact with said rotary peripheral surface, and the action of the jet stream onto the rotary main shaft 12 is softened, so noise and vibration can be reduced properly.
