A motor includes a rotor part having a rotor shaft and a rotor magnet, a stator part oppositely disposed to the rotor magnet via a gap space, a bearing rotatably supporting the rotor shaft, a spring member abutting with one end of the rotor shaft to urge the rotor shaft in an axial direction. A spring member side restricting part is provided in the spring member to prevent fluctuation in the radial direction of the rotor shaft and a rotor shaft side restricted part is provided in the rotor shaft and engages with the spring member side restricting part.
