<P>PROBLEM TO BE SOLVED: To provide a magnetic field shielding mechanism that prevents a magnetic body member connected to a magnet from being magnetized, and to provide an actuator using the magnetic field shielding mechanism. <P>SOLUTION: In a magnetic field shielding mechanism 50, a ring-shaped second magnet 52 magnetized in a radial direction is disposed on a magnetic pole side of a first magnet 3a magnetized in a first direction so that the first direction intersects the radial direction, causing a magnetic field from the first magnet 3a toward the second magnet 52 to be shielded or reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
