Claims

[Scope of utility model registration request]

In a rotary magnet comprising a yoke equipped with an electromagnetic drive coil and a rotatable rotor equipped with a movable pole facing the magnetic pole of the yoke, the magnetic pole of the yoke is arranged in a direction that changes the area facing the movable pole of the rotor. A rotary magnet comprising a rotary type magnetic pole part that acts in a direction to change the facing distance between the movable pole of the rotor and an armature type magnetic pole part that acts in a direction that changes the facing distance between the movable pole of the rotor.
