。 A rotating shaft supported on both sides within the bearing holder by a bearing mounted on the bearing holder, a stator core fixed to the bearing holder, and a stator core provided opposite to the circumferential side of the stator core on one end side of the rotating shaft. a rotor case in the form of a container with a bottom fixed at its center; an annular driving magnet disposed at the bottom of the rotor case and having an inner circumference facing the outer circumference of the stator core; and a counter rotor of the bearing on the rotating shaft. A holding member made of a magnet or magnetic material is provided on the side, and the holding member is attached to the bearing holder adjacent to the holding member, and the magnetic action with the holding member causes the rotor to move along with the rotating shaft in a direction opposite to its own weight. A brushless motor comprising a holding member made of an attracting magnetic material or a magnet.
