The screw position adjustment device includes: a thread () immovable with respect to the material supply cylinder, and having a through-hole () extending in the axial direction; a position adjustment nut () threadably engaged at the outside peripheral face of a thread for determining the retracted position; a fastener () for securing the position of the position adjustment nut; and a casing () covering the position adjustment nut and the fastener, and having an opening () for moving closer to the position adjustment nut and the fastener.
