摘要

The motor has a movable unit with a magnet frame (121) disposed between outer and inner stators (111, 112). A cylindrical magnet (122) is formed as a single body and installed on an outer circumferential surface of the frame. Slits are formed on the outer circumference of the magnet and are spread to a certain degree when the magnet is installed at the frame so that the magnet is easily mounted at the frame.
