Claims

[Scope of Claim for Utility Model Registration] (1) A permanent magnet that is fixedly attached 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 supports the rotary shaft of the rotary movable body. a fixed base member; a fixed base member fixedly disposed on a plane orthogonal to the rotational axis facing the permanent magnet;
and a planar coil in which a plurality of conductive wires extending in the radial direction are wound in a planar shape, and the rotation is caused by the electromagnetic action of the permanent magnet and the current flowing through the conductive wires extending in the radial direction in the planar coil. In a rotary actuator that rotates a movable body in both forward and reverse directions, a conductive wire extending in the radial direction of a plane coil that performs electromagnetic action with a permanent magnet passes near the center of rotation of the rotary movable body. , comprising: a bearing member having a bridge portion that straddles a conductive wire near the center of rotation of the rotary movable body in the planar coil; and a rotary movable body having one end of the rotary shaft pivotally supported by the bearing member. rotary actuator. (2) The rotary actuator according to claim (1) of the utility model registration, characterized in that a connecting shaft for connecting to the rotary movable body is provided protruding from the bridge portion of the bearing member. (3) Utility model registration claim no.
Rotary actuator described in item ).
