<p>A two-shaft extruder includes a pair of rotor shafts 1 rotatably disposed with a distance therebetween diminishing toward the leading ends thereof and a screw blade 2 mounted to the leading end of each one of the pair of rotor shafts 1, one screw blade 1b intruding into the pitch of the other screw blade 1a; and a drive unit M mounted the base end of each one of the pair of rotor shafts 1 for rotatably driving the rotor shaft 1 associated therewith. There is provided a screw blade contact preventing mechanism SS configured to allow a predetermined phase difference between the pair of rotor shafts 1, while inhibiting a phase difference greater than the predetermined phase difference when the pair of rotor shafts 1 are rotatably driven respectively.</p> |
