PROBLEM TO BE SOLVED: To provide a tilting pad bearing device having a structure not restricting tilting of a pad by an oil supply nozzle, capable of enduring an oil supply pressure, and having excellent assemblability.SOLUTION: A tilting pad bearing device supporting a rotating shaft, includes a plurality of pads supporting the rotating shaft, and a housing supporting the plurality of pads. The housing includes a first oil supply passage extended in the circumferential direction, and second oil supply passages for communicating the first oil passage and an inner peripheral face of the housing at positions corresponding to the plurality of pads. The pads include third oil supply passages having oil supply grooves at an upstream side of the inner peripheral face, and communicating the oil supply grooves and back faces of the pads. An oil supply nozzle is disposed to connect the second oil supply passages and the third oil supply passages, and the oil supply nozzle has a bellows structure portion, and includes a seal ring at one end.SELECTED DRAWING: Figure 3 |
