クチユエータ。[Claims for Utility Model Registration] A permanent magnet that is fixed to a rotary movable body, has a magnetization direction in the axial direction of the rotary shaft, and is flat in the magnetization direction, and a fixed base member that pivotally supports the rotary shaft of the rotary movable body. and a planar coil fixed on a plane perpendicular to the rotational axis of the fixed base member, facing the flat permanent magnet, the electromagnetic action of the permanent magnet and the current flowing through the planar coil. According to
In a rotary actuator configured to rotate a rotary movable body, the rotary shaft has a first shaft fixed to the rotary movable body and a second shaft supported by a fixed base member, and A hole opening in the axial direction is formed at the end of either the first shaft or the second shaft, and the end of the other shaft is loosely fitted into the hole, and the hole or the second shaft is loosely fitted into the hole. The thrust bearing is characterized in that a conical recess is formed in one end face of the other shaft, and a steel ball is disposed between the recess and the other end face. Rotary actuator.
