Abstract

See full text

A plasticizing device includes a driving motor, a rotor rotated around a rotation axis by the driving motor and having a groove forming surface on which a groove is formed, a barrel having an opposed surface opposed to the groove forming surface, a communication hole into which a plasticized material flows being provided in the barrel, a housing section housing the rotor, a first restricting section fixed to the rotor and having a first contact surface facing the barrel side, and a second restricting section fixed to the housing section, opposed to the first contact surface, and having a second contact surface contactable with the first contact surface. Movement of the rotor along the rotation axis is restricted by the first restricting section and the second restricting section. The groove forming surface is separated from the opposed surface at a predetermined interval in a state in which the first contact surface and the second contact surface are in contact.
