More Information
Summary:A screw driving device includes: a plasticization motor; a rotation drive shaft provided coaxially with a screw and configured to rotate the screw; and a transmission mechanism configured to decelerate rotation of the plasticization motor and transmit the rotation to the rotation drive shaft. The transmission mechanism includes: a speed reducer whose output shaft is coupled to the rotation drive shaft; a drive rotation member provided in the plasticization motor; a driven rotation member provided on an input shaft of the speed reducer; and one endless string-shaped force transmission member wound around the drive rotation member and the driven rotation member.
