Abstract

A MINIATURE MOTOR HAS A BEARING DEVICE SUPPORTING A ROTATION SHAFT ( 16, 71, 86 ) OF A ROTOR 9 13, 68, 83 ) DISPOSED INSIDE A CASING ( 12, 61, 82 ) HAVING AN INNER SURFACE ON WHICH A STATOR ( 11, 65, 81 ) IS MOUNTED. IN THE BEARING DEVICE, A FLAT PORTION ( 19, 64, 88, 89 ) IS FORMED TO THE CASING AND BEARING ( 14, 72, 84, 85 ) FOR SUPPORTIONG THE ROTATION SHAFT IN A RADIAL DIRECTION THEREOF IS WELDED TO THE FLAT PORTION BY A LASER BEAM WELDING METHOD. THE MOTOR HAVING THE BEARING DEVICE OF THE ABOVE STRUCTURE HAS A REDUCED AXIAL LENGTH AND A COMPACT STRUCTURE AND IS UTILIZED FOR A COMPACT DISK PLAYER.
