A thrust converter includes reciprocation movement means reciprocation-rotation conversion means for converting reciprocating movement of the reciprocation movement means into rotational movement; rotation-reciprocation conversion means for converting rotational movement of the reciprocation-rotation conversion means; and reaction-force receiving means for supporting reaction force stemming from reciprocation movement of the rotation-reciprocation conversion means. Thrust imparted to the reciprocation movement means can be imparted to a load while being amplified or reduced, through employment of a compact and simple construction.

A cylinder servo motor includes a servo motor having a rotor and a stator; a cylinder servo main unit which is connected to a rotary shaft of the rotor of the servo motor by way of a ball screw nut and which has a ball screw shaft, the ball screw shaft moving in an axial direction; a rotation sensor for detecting a rotary position of the servo motor; and control means for controlling the rotation sensor and the servo motor. The cylinder servo motor main unit, the rotation sensor, and the control means are integrated together, thereby providing a cylinder servo motor which obviates a necessity of wiring a line between the servo motor, the rotation sensor, and the control device section at a location to which the cylinder servo motor is to be shipped.
