Beschreibung
Zusammenfassung:	A motor includes a rotor having a rotation shaft and a bearing mounted to the rotation shaft, a stator surrounding the rotor, a heat dissipation member provided on one side of the rotor in an axial direction of the rotation shaft, and a resin portion covering the stator and at least a part of the heat dissipation member. The heat dissipation member has a first concave portion surrounding the bearing from an outer side in a radial direction about the rotation shaft, and a second concave portion famed on an inner side of the first concave portion in the radial direction.
