1. A stator assembly apparatus configured to assemble a stator by, from inside a stator core, inserting a coil into slots in the stator core, electrically-insulating members being mounted to the slots, the apparatus comprising:
a plurality of guide members that are provided to respectively correspond to the slots, are provided in a manner enabling insertion into and withdrawal from inside the electrically-insulating members in a central axial direction of the stator core, and are arranged in a radial direction of the slots in a state of having been inserted inside the electrically-insulating members;
a presser configured to cause the coil to move inside the electrically-insulating members by pressing the coil radially outward with respect to the stator core; and
a controller configured to control movement of the plurality of guide members in the central axial direction of the stator core, wherein
each time the coil moved by the presser comes into contact with or approaches a guide member positioned most radially inside from among the plurality of guide members inside the electrically-insulating members, the controller causes the guide member positioned most radially inside to move so as to sequentially withdraw from within the electrically-insulating members.
