Abstract
A plasticizing device includes a rotor having a rotation shaft and a groove-formed surface that includes a groove formed in the rotation direction and that inclined from the rotation shaft in a radial direction with respect to a radial direction orthogonal to the center axis, a facing unit having a facing surface inclined so as to face the groove-formed surface in the radial direction, a heater heating a material to be supplied between the facing surface and the rotor, and a communication hole through which the material plasticized by heat of the heater flows, a drive motor generating rotational driving force, a connection unit fitting to the rotor in a direction along a rotation shaft of the drive motor, connecting the rotation shaft of the drive motor and the rotor to each other, and transmitting the rotational driving force of the drive motor to the rotor, and an elastic member disposed between the rotor and the connection unit.
