<P>PROBLEM TO BE SOLVED: To suppress heat generation of a sliding part of a sealing member and a rotating shaft member. <P>SOLUTION: The sealing structure 10 of the rotating shaft member is equipped with the rotating shaft member 12 and the sealing member 14 having a lip part 24. In the rotating shaft member 12, a cooling liquid introduction hole 16 is formed along the rotation axis direction. Thus, when the cooling liquid is supplied from a cooling liquid supply part 50 with the cooling liquid supply part 50 communicated with a cooling liquid introduction port 18 of the cooling liquid introduction hole 16, this cooling liquid can be introduced to the cooling liquid introduction hole 16 via the cooling liquid introduction port 18 and the cooling liquid can be introduced to a position overlappnig with the lip part 24 in the cooling liquid introduction hole 16 in the rotation axis direction. Hence, it is possible to cool the sliding part between the outer circumference part of the rotation shaft member 12 and the lip part 24 by the cooling liquid introduced to this cooling liquid introduction hole 16. <P>COPYRIGHT: (C)2008,JPO&INPIT |
