A motor includes ( 1 ) a rotor including a permanent magnet fixed to a rotor shaft, ( 2 ) a stator including a rotor insertion hole and an inner periphery, where the inner periphery of the stator is oppositely disposed to the permanent magnet of the rotor and where the rotor insertion hole has a prescribed space and the rotor is inserted into the rotor insertion hole, ( 3 ) a bearing supporting one end of the rotor shaft, and ( 4 ) a bearing holder including a bearing insertion hole into which the bearing is inserted. In this motor, when an outer diameter of the permanent magnet of the rotor is set to be "A", an inner diameter of the bearing insertion hole of the bearing holder is set to be "B", and an inner diameter of the rotor insertion hole of the stator is set to be "C", a relationship of "A<B<C" is satisfied.
