Claim 13:
14. A manufacturing method of an armature that includes an armature core provided with a plurality of slots extending in an axial direction, a plurality of first segment conductors including a first leg portion extending in the axial direction, and a plurality of second segment conductors including a second leg portion extending in the axial direction, the manufacturing method comprising:
a step of disposing each of the plurality of first segment conductors on one side of the armature core in the axial direction and disposing each of the plurality of second segment conductors on the other side of the armature core in the axial direction such that a first surface that is provided on a tip end portion side of each of the first leg portions of the plurality of first segment conductors and that is provided so as to extend along the axial direction and a second surface that is provided on a tip end portion side of each of the second leg portions of the plurality of second segment conductors and that is provided so as to extend along the axial direction face each other in one slot or on an outer side of the one slot in the axial direction; and
a step of joining the first surface of the first leg portion and the second surface of the second leg portion that are disposed so as to face each other, wherein
the first leg portion has a first leg portion body portion that is provided so as to be continuous from a first surface disposition portion on which the first surface is provided and on an opposite side of the first leg portion from the tip end portion, and that has a thickness in a joining direction, which is a direction in which the first surface and the second surface are joined, larger than a thickness of the first surface disposition portion,
the second leg portion has a second leg portion body portion that is provided so as to be continuous from a second surface disposition portion on which the second surface is provided and on an opposite side of the second leg portion from the tip end portion, and that has a thickness in the joining direction larger than a thickness of the second surface disposition portion, and
the step of disposing the first segment conductor and the second segment conductor is a step of disposing the first segment conductor and the second segment conductor so that a first clearance portion is provided between the tip end portion of the first leg portion and the second leg portion body portion in the axial direction and so that a second clearance portion is provided between the tip end portion of the second leg portion and the first leg portion body portion in the axial direction.
