Abstract:
A motor includes a rotor, a stator, and a support member. The rotor includes a rotor magnet, a magnet holding portion, and spoke portions. The stator includes a plurality of coils and a stator core. The support member includes a stator holding portion and a mount portion. The mount portion includes a plurality of slits extending radially inward from a radially outer end portion of the mount portion. The slits each have openings in an outer circumferential end and an upper surface of the mount portion. The openings of the slits positioned in the upper surface of the mount portion are positioned between the coils adjacent to each other in the circumferential direction when viewed in the axial direction.
