Claim 10:
11. A motor comprising:
a housing; and
a stator disposed in the housing,
wherein the housing includes a body and a plurality of protrusions protruding inward from an inner surface of the body and disposed to be spaced apart from each other in a circumferential direction,
the stator includes a stator core and a coil wound around the stator core,
an outer circumferential surface of the stator core forms a circle at a radius,
the stator core includes yokes and teeth protruding from the yokes in a radial direction,
the yoke includes a first region disposed on the same radius as that of the tooth and second regions extending from both ends of the first region in the circumferential direction, and
an inner surface of the protrusion is in contact with an outer surface of the yoke disposed in the second region,
wherein each of the plurality of protrusions is not disposed in a first width area between two virtual lines each extending along a corresponding one side surface of one of the plurality of teeth of the stator core, plus an additional width at each side of the two virtual lines, the additional width being at least 10 percent of a width of the first width area.
