The linear motion mechanism (3) and the electric motor (2) are arranged in the axial direction with a rotary input-output shaft (5) of the linear motion mechanism (3) interposed therebetween. In the electric motor (2), orientation of a magnetic pole generating interlinkage flux is parallel with a rotation shaft of the motor. The linear motion mechanism (3) has a thrust bearing (34) for retaining a reaction force against a load in the axial direction in association with linear motion of the linear motion part (6). The control unit (CU) has a thrust force applying section (54) for applying a thrust force such that a force acting in the axial direction of the rotary input-output shaft (5) due to interlinkage flux between the stator (7) and the rotor (8) causes generation of a force, in the axial direction, acting on the thrust bearing (34).
