1. A method for assembling a coil, the method comprising:
a step of inserting insulating paper into a slot of a stator core;
a step of protruding a plurality of pawl portions from an inner peripheral surface of a defense cuff support, wherein a pawl portion corresponds to a tooth of the stator core;
a step of inserting a blade into the slot into which the insulating paper is inserted; and
a step of inserting the coil into the slot into which the blade is inserted, the coil being inserted in a direction opposite to a direction in which the blade is inserted into the slot, wherein, in the step of inserting the coil, the blade is pulled out from the slot along with the insertion of the coil into the slot, wherein:
the defense cuff support is arranged on a side of the stator core opposite to a side where the blade is inserted; and
a width of a gap between end portions of the insulating paper inserted into the slot of the stator core, the end portions facing each other, is larger than a width of a gap between the pawl portions neighboring each other.
