Abstract:
A nozzle holding tool according to an aspect of the present invention holds a nozzle which holds a wire rod for forming a coil. The nozzle holding tool is coupled to a rotary shaft. The nozzle holding tool is provided with: a nozzle fixing part; a shaft coupling part; a nozzle arm; a coupling arm; and an elongation part. The nozzle arm is provided with the nozzle fixing part. The nozzle arm is provided so as to extend in parallel with a virtual plane perpendicular to the axial direction of the rotary shaft. The coupling arm couples the nozzle arm and the rotary shaft together in a state where the nozzle fixing part and the shaft coupling part are separated from each other. The elongation part is elongated/contracted in the direction parallel to the virtual plane in a first region which ranges from the nozzle fixing part through the nozzle arm and the connection arm to the shaft connection part.
