<P>PROBLEM TO BE SOLVED: To provide a rotating shaft structure of a motor for a galvano-scanner achieving low inertia and high rigidity by a simple structure. Ž<P>SOLUTION: In the rotating shaft structure of the motor for the galvano-scanner, a rotor 70 composed of a permanent magnet is rotated by controlling a current flowing through a stator 54, and a rotating shaft 52 having the rotor is swingingly operated. In the rotating shaft 52, a through-hole 52b penetrated from an outer peripheral surface 52a to an outer peripheral surface 52a on an opposite side across the axial center Q, is formed. The permanent magnet is inserted into the interior of the through-hole 52b to constitute the rotor 70. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
