Abstract:
A magnet rotor includes a drive arm with a rotary shaft, and an anisotropic permanent magnet having an axis of magnetization. The drive arm is composed of a light transmitting resin. The magnet has a cylindrical shape with a hollow center portion through which the rotary shaft is disposed. The drive arm and the permanent magnet are bonded together by a light curable resin adhesive.
