Abstract
A magnet rotor includes a drive arm with a rotary shaft and a hollow cylindrical-shaped permanent magnet bonded by a light curable resin. The drive arm is composed of a light transmitting resin, and the permanent magnet is an anisotropic magnet with an axis of easy magnetization. During fabrication, the light curable resin is applied to the rotary shaft, and a hollow portion of the magnet is fitted to the rotary shaft. While holding the magnet in a position where a direction of the axis of easy magnetization corresponds to a magnetic field direction, the drive arm is irradiated with light to cure the resin and bond the drive arm and the permanent magnet.
