Summary:PROBLEM TO BE SOLVED: To provide a fluid coupling that has a bearing structure that can sufficiently supply lubricating oil to a radial bearing adjacent to a thrust bearing.SOLUTION: A fluid coupling comprises: an impeller 1 and a runner 2 arranged so as to face each other; a driving shaft 11 to which the impeller 1 is fixed; an output shaft 12 to which the runner 2 is fixed; a radial bearing 40 and a thrust bearing 42 that rotatably support the driving shaft 11; and a lubricating oil supply system 50 that supplies lubricating oil to the radial bearing 40 and the thrust bearing 42. The radial bearing 40 comprises: a supporting surface 62 that supports an outer peripheral surface of the driving shaft 11; a thrust bearing side end surface 63 that faces the thrust bearing 42; and an anti-thrust bearing side end surface 64 located on the side opposite to the thrust bearing side end surface 63. An annular groove 68 arranged adjacently to the thrust bearing side end surface 63 is formed in the supporting surface 62. The radial bearing 40 comprises an oil passage 69 that extends from the annular groove 68 to the anti-thrust bearing side end surface 64.SELECTED DRAWING: Figure 2 【課題】スラスト軸受に隣接するラジアル軸受に潤滑油を十分に供給することができる軸受構造を有した流体継手を提供する。【解決手段】流体継手は、互いに向き合って配置されたインペラ１およびランナ２と、インペラ１が固定された駆動軸１１と、ランナ２が固定された出力軸１２と、駆動軸１１を回転可能に支持するラジアル軸受４０およびスラスト軸受４２と、ラジアル軸受４０およびスラスト軸受４２に潤滑油を供給する潤滑油供給システム５０とを備える。ラジアル軸受４０は、駆動軸１１の外周面を支持する支持面６２と、スラスト軸受４２に面するスラスト軸受側端面６３と、スラスト軸受側端面６３とは反対側に位置する反スラスト軸受側端面６４とを有する。支持面６２には、スラスト軸受側端面６３に隣接した円環溝６８が形成されている。ラジアル軸受４０は、円環溝６８から反スラスト軸受側端面６４まで延びる油路６９を有する。【選択図】図２
