Abstract
A miniature motor has a rotor (13, 68, 83) disposed inside a casing (12, 61, 82) having an inner surface on which a stator (11, 65, 81) is mounted. A bearing device supporting a rotation shaft (16, 71, 86) of the rotor comprises a bearing (14, 72, 84, 85) for supporting the rotation shaft in a radial direction thereof. The bearing device also comprises a flat portion (19, 64, 88, 89) formed by the casing and to which the bearing is welded by a laser beam welding method. A motor having a bearing device of the defined structure has a reduced axial length and a compact structure and may be used for a compact disc player. <IMAGE>
