特徴とする工作機械の回転軸流体シール構造。 In a fluid seal structure that prevents the flow of a medium between two chambers that are separated by a plane that rotates relative to each other while contacting each other, one of the contact surfaces has a plurality of grooves, and a passage connecting these grooves. A machine tool characterized in that a fluid supply means for introducing fluid at an appropriate pressure into the groove and the passage is connected thereto, and a spring is engaged for urging the planes in a direction in which the planes are brought into pressure contact with each other. Rotating shaft fluid seal structure.
