Abstract
A hydrodynamic torque transmitting device is disclosed that overcomes problems created by the presence of a thrust washer therein. In a torque converteraccording to the present invention, a pistonis disposed between a front coverand a turbineto form a front chamber F on a front cover side and a rear chamber R on a turbine side, and can move toward and away from the front coverby means of a hydraulic pressure differential created between the front and rear chambers F and R. The pistonhas a disk shaped body, and a frictional coupling portion (friction facing) disposed on a outer peripheral portion of the bodythat serves to frictionally engage with the front cover. The turbine huband the front coverhave opposing portions () that oppose each other across an axial space. The pistonhas a support portionthat axially supports the turbinewhen the pistonmoves to a position near the front cover. When the pistonmoves to a position closest to the front cover, an axial space is maintained between the opposing portions ().
