    摘要： A rotation shaft supporting structure with which the radial clearance between the bearing surface of an upper tilting pad on which self weight of the rotation shaft does not exert and rotating surface of the journal of the rotation shaft can be adjusted so that a high pressure oil film is formed in the clearance and carryover of lubrication oil from an upstream pad to its adjacent downstream pad is prevented. A plurality of bearing pads (40) are disposed in a bearing housing (30) to surround coaxially a journal j of a rotation shaft, a spring (80) is disposed between the bearing housing (30) and an upper pad (40a, 40b) near downstream side end of the pad in relation to the rotation direction of the journal to push the end part of the pad radially inward, and an oil supply nozzle (50) is mounted to the bearing housing (30) to be located adjacent to the upstream and downstream side end of each pad(40), the upstream side nozzle is to supply lubrication oil to the bearing surface of the pad and the downstream side nozzle is to inject oil toward the journal surface to prevent carryover of lubrication oil from the bearing surface of the upstream pad to that of the downstream pad dragged by the rotating surface of the journal, the nozzles also serving as stoppers to prevent rotational movement of the pad (40).

    摘要： Disclosed is a shaft sealing device (100) including: a housing (60) in which an annular recessed portion (61) is formed and which is fixed to a stator; a sealing body (20), a radially outer portion of which is accommodated by the annular recessed portion (61); and a high pressure-side sealing plate (40) that is disposed along the sealing body (20) in a high pressure region (Hs). An inflow groove (66) is formed in any member of the housing (60), the high pressure-side sealing plate (40), and the sealing body (20) such that a fluid flows through the sealing body (20) from a low pressure region (Ls) during a non-normal operation in which pressure in the high pressure region (Ls) is higher than pressure in the high pressure region (Hs). A communication path (69) is formed in the housing (60) such that the inflow groove (66) and a space in the high pressure region (Hs) communicate with each other via the communication path (69).
