PROBLEM TO BE SOLVED: To provide a sealing device capable of restraining acceleration of abrasion against high pressure and lessening the problem of heat generation due to frictional heat or the like to improve durability of a rotating shaft seal as a sealing device coping with high pressure of a coolant. SOLUTION: A pressure reducing seal is disposed separately from the rotating shaft seal. The pressure reducing seal is provided with a lip part formed by extending the tip part of the lip on a fluid storing chamber side on the fluid storing chamber side from the rotating shaft seal having a seal element interposed between a housing and a rotating shaft to be brought into sliding contact with the rotating shaft, and a rubber-made seal member disposed on the fluid storing chamber side from the seal element. |
