A power-actuated vise apparatus includes a first jaw which is disposed on a base, and a second jaw which is supported by a carrier to be movable in a longitudinal direction by an angular force in an initial course. The carrier is further pressed by a linear force in a subsequent course to bring the second jaw into tightened engagement with a workpiece against the first jaw. A servo control mechanism is disposed to drive a torque transmitting member so as to transmit a torque force. A force coupler unit is configured to couple the torque transmitting member to the carrier and to take up the torque force from the torque transmitting member to result in generation of the angular force and the linear force.
