ABSTRACT OF THE DISCLOSURE A fluid torque converter comprising a pump wheel connected to a driving power source, a turbine wheel connected to a driven member, the pump wheel and turbine wheel being connected to each other via a working fluid, and a one-way clutch of on-off type provided between the pump wheel and turbine wheel and adapted to mechanically connect the pump wheel and turbine wheel together when the one-way clutch is in a coupled state. The one-way clutch has a driving clutch member connected to the pump wheel and provided with a first conical surface, and a driven clutch member connected to the turbine wheel and provided with a second conical surface in opposed and parallel relation to the first conical surface. A plurality of elastic wedge rollers are provided between the first and second conical surfaces in a circumfer- entially spaced relation. The driven clutch member is actuated hydraulically so as to be engaged with and dis- engaged from the driving clutch member, and takes an operative position in which the driven clutch member is mechanically connected to the driving clutch member via the wedge rollers, and an inoperative position in which such mechanical connection between the driven and driving clutch members is cut off.
