A stator core support device includes two support members that are radially opposed to a stator core such that a central axis of the stator core is interposed between the support members, and an inverting mechanism that inverts the two support members. Each of the support members has a radially opposed face that is radially opposed to the stator core, a first axially opposed face that is axially opposed to a first axial side of the stator core, and a second axially opposed face that is axially opposed to a second axial side of the stator core. While the inverting mechanism is inverting the two support members that hold the stator core, the stator core is moved in the axial direction relative to the two support members.
