Abstract
A motor, may include a rotor having a shaft which has its center on a center axis extending in one direction; a stator which surrounds the rotor in the axial circumference, and includes a plurality of coils; and bus bars connecting coil ends extending from the coils. The bus bars may include a plate shape member bent in a thickness direction, a width direction of the bus bars being identical to an axial direction of the motor. Each of the bus bars may include a main body portion, and a coil end connection portion which extends from the main body portion and grips one of the coil ends at an opening that is open toward one direction within a plane perpendicular to the axial direction.
