The linear motion mechanism and the electric motor are arranged in the axial direction with a rotary input-output shaft of the linear motion mechanism interposed therebetween. In the electric motor, orientation of a magnetic pole generating interlinkage flux is parallel with a rotation shaft of the motor. The linear motion mechanism has a thrust bearing for retaining a reaction force against a load in the axial direction in association with linear motion of the linear motion part. The control unit has a thrust force applying section for applying a thrust force such that a force acting in the axial direction of the rotary input-output shaft due to interlinkage flux between the stator and the rotor causes generation of a force, in the axial direction, acting on the thrust bearing.
