PCT No. PCT/JP81/00011 Sec. 371 Date Jul. 22, 1981 Sec. 102(e) Date Jul. 22, 1981 PCT Filed Jan. 16, 1981 PCT Pub. No. WO81/02051 PCT Pub. Date Jul. 23, 1981.A seal-ring type shaft-sealing device for sealing a highly pressurized fluid such as gas and liquid has a seal ring whose inner circumference is previously formed ovally and is held so as to incline the longitudinal axis of the ellipse to the gravity force direction in the revolutional direction of the rotating shaft at an angle smaller than 90 DEG thus improving the floating characteristic and eliminating the irregular distribution in temperature during operation. The device can be used, for example, in a turbine generator.
