Claims

[Claims for Utility Model Registration] (1) A guide cylinder that appears in the center hole of the stator core and rotates at a predetermined angle when protruding from both end faces of the stator core, and a guide cylinder that rotates at a predetermined angle when protruding from both end faces of the stator core, and a direction from the head at the tip of the guide cylinder toward the inner circumference of the stator core. A nozzle that protrudes from the stator core and has a tip proximate to the groove of the stator core but is not inserted into the groove, and a former that guides a loop of conductor protruding from both end faces of the stator core to a predetermined position, and the conductor is fed out through the guide tube and the nozzle. In a series winding device for a stator core, which forms a coil by linearly inserting a conducting wire into a predetermined groove of the stator core to form a loop, the conducting wire of the stator core is inserted freely into a selected groove out of the grooves that are not inserted. A direct winding device for a stator core, characterized in that it is provided with an auxiliary jig. (2) The auxiliary jig has a column-shaped outer part that fits inside the groove of the stator core, a plate-shaped inner part that projects inward from the groove of the stator core, and a part that fits inside the stator core when viewed from the side. 2. The series winding device for a stator core according to claim 1, further comprising a distal end portion tapering toward the stator core.
