Abstract
A molding machine includes a drive unit which, in turn, includes comprises a rotary motor and a thrust generator. The rotary motor includes a shaft which is rotatable and axially movable. The shaft is connected to a movable body so as to rotate the movable body by the rotary motor and to reciprocate the movable body by the thrust generator. Thus, the drive unit is substantially composed of a single rotary motor which functions for rotating and reciprocating the movable body, such as a screw.
