Claim:
1. An armature comprising: a core having first to sixth slits formed successively in a circumferential direction; a first inside coil wound between the first slit and the third slit; a second inside coil wound between the fifth slit and the first slit; a third inside coil wound between the third slit and the fifth slit; a first outside coil wound between the sixth slit and the second slit; a second outside coil wound between the second slit and the fourth slit; a third outside coil wound between the fourth slit and the sixth slit, a shaft that penetrates a center of the core; and a commutator that rotates with the armature, the commutator being fixed to the shaft, wherein the commutator is divided into three segments, along a circumferential direction, which are a first segment, a second segment and a third segment, wherein the second inside coil and the second outside coil are connected in parallel with each other between the first segment and the second segment, wherein the first inside coil and the third outside coil are connected in parallel with each other between the second segment and the third segment, wherein the third inside coil and the first outside coil are connected in parallel with each other between the third segment and the first segment, wherein the first inside coil, the second inside coil and the third inside coil are arranged on a rotation axis side of the respective slits such that the first to third inside coils form a triangle as viewed from a direction of axis line of the rotation axis, and wherein the first outside coil, the second outside coil and the third outside coil are arranged such that the first to third outside coils surround the first inside coil, the second inside coil and the third inside coil and such that the first to third outside coils form a triangle as viewed from the direction of axis line of the rotation axis.
