Patent ID: 8350421

Claim:
A motor comprising: a stator which is formed with a rotor arrangement hole; a rotor which is disposed in the rotor arrangement hole; and a plate-like member which is disposed on at least one end side in an axial direction of the stator; wherein an outer peripheral portion of the plate-like member comprises a recessed part which is cut out toward an inner side in a radial direction; wherein a peripheral edge part of the recessed part of the plate-like member is joined with an end face of the stator so that an edge of the peripheral edge part on a side of the plate-like member opposite to an end face of the plate-like member that contacts the end face of the stator is melted by irradiation of a laser beam and metal of the peripheral edge part of the recessed part of the plate-like member having been melted is flowed and extended over the end face of the stator to form a joining part on the end face of the stator; and wherein the joining part of the peripheral edge part with the end face of the stator is exposed to an exterior of the stator.
