Claims

[Claims for Utility Model Registration] (1) A stator, a rotor formed in a cylindrical shape with a bottom and provided facing the circumferential side of the stator, and a rotating shaft having one end fixed to the bottom of the rotor. , bearings fitted to the rotating shaft at a predetermined interval and at least one of which is a ball bearing; a bearing holder for holding these bearings; and a bearing holder provided facing each of the rotor side and the stator side A motor comprising: a magnet that applies a force in a direction in which the rotor moves away from the stator; and a pressing member provided to press the inner ring of the ball bearing against the rotating shaft. (2) The motor according to claim 1 of the utility model registration claim, characterized in that magnets are provided in the rotor and the stator. (3) The motor according to claim 2, wherein the magnet is provided in a recess formed in the stator. (4) The motor according to claim 1, wherein the magnet is provided in a frame that attaches the rotor and stator.
