Abstract
The invention provides a tilting-pad thrust bearing that requires less oil supply and a rotary machine having the same. A tilting-pad thrust bearingcomprises: multiple oil inletsdisposed in spaces between pads; multiple outflow guide grooveseach formed near the inner circumferential edge of the sliding surface of the padsuch that the outflow guide groovesextend in a circumferential direction; and multiple inflow guide groovesprovided separately from the outflow guide groovesand formed at the leading ends of the sliding surfaces of the padsso as to be located more radially inward than the oil inlets. Each outflow guide grooveis open to the sliding surface and the trailing end surface of the pad. Each inflow guide groovesis open to the leading end surface and the sliding surface of the pad
