Claims

[Scope of utility model registration request]

In a thrust bearing that includes a housing that covers a thrust collar fixed to a rotating shaft and a plurality of thrust pads that receive the thrust collar within the housing, a plurality of high-pressure oil discharge grooves are arranged intermittently along the periphery of the thrust pad. A thrust bearing with a high-pressure oil discharge groove, characterized in that an oil passage for supplying high-pressure oil to each of these high-pressure oil discharge grooves via an orifice is bored in the thrust pad.
