PURPOSE:To simplify the constitution of the titled injection mechanism, by providing a coil to the nut threaded with the screw provided onto a screw shaft to form a rotor and forming a motor by the coil embedded in a part of the screw shaft. CONSTITUTION:A coil 11 is integrally embedded in the outerperiphery of the nut 10 threaded with a ball screw 2 and constitutes a motor M1 along with a stator 17 constituting a coil 16. A coil 22 is embedded in the outer periphery of a rotor 21 and constitutes a motor M2 along with a stator 24 constituted by the coil 23 provided to a housing. An injection speed can be controlled by controlling the current value to the motors. |
