Abstract: An armature has a plurality of armature cores arranged in a line in a first direction, coils wound on an area of the armature cores in a second direction, a carrier provided with a space in which to dispose the coils left in a third direction orthogonal to the first direction and the second direction with respect to the armature cores, and at least one mounting member to fix the armature cores and the carrier. The armature cores are fixed to the mounting member by first bolts, and the carrier is fixed to the mounting member by second bolts. The at least one mounting member, the first bolts, and the second bolts are disposed in positions not overlapping the coils when viewed from the third direction.

Abstract: Two teeth on which windings are wound, and a teeth connecting portion disposed between the two teeth, connecting the teeth together, and having a mounting hole formed therein, are arranged in a line in a second direction, which is an arrangement direction. The teeth connecting portion has a support that supports the windings. The support has projections protruding from both end portions in the second direction of the teeth connecting portion to both sides in a first direction which is a width direction, and spaces formed between the projections in the second direction.
