摘要 |
An actuator rotatable about a support shaft rectilinearly movable along axis of a shaft and rotatably movable about the shaft includes a cylindrical magnet extending about the shaft. The cylindrical magnet has a plurality of poles in the radial direction and magnetized boundaries between poles of opposite polarity extending in a circumferential direction of the magnet and extending in an axial direction of the magnet.
