1. An armature comprising:
an armature core provided with a plurality of slots extending in an axial direction;
a plurality of first segment conductors disposed on one side of the armature core in the axial direction and including a first leg portion that extends to the other side of the armature core in the axial direction;
a plurality of second segment conductors disposed on the other side of the armature core in the axial direction and including a second leg portion that extends to the one side in the axial direction; and
a coil portion including a joint portion in which a first surface that is provided on a tip end portion side of each first leg portion 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 second leg portion of the plurality of second segment conductors and that is provided so as to extend along the axial direction are joined in one of the slots or on an outer side of one of the slots in the axial direction, 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
between the first segment conductor and the second segment conductor that are joined to each other in the joint portion, 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 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.
