Rotary reciprocating drive actuator

A rotary reciprocating drive actuator, comprising:

• a movable body including:
• a shaft part to which a movable object is connected at one end portion side of the shaft part, and
• a magnet fixed to an other end portion side of the shaft part, the movable body being supported to be configured to perform a reciprocating rotation about an axis;
• a core assembly including:
• a core body including a plurality of magnetic poles facing an outer circumference of the magnet to sandwich the magnet,
• a coil body that is wound around the core body and that is energized to generate a magnetic flux interacting with the magnet to cause the reciprocating rotation of the movable body, and
• a magnet position holding portion that generates a magnetic attraction force between the magnet position holding portion and the magnet to define a reference position of the reciprocating rotation;
• and
• a circuit board disposed to cover the core assembly at the other end portion side,
• wherein the coil body includes a bobbin portion around which a coil is wound on an axis perpendicular to the shaft part, a terminal support portion protruding from the bobbin portion toward the other end portion and extending parallel to the axis, and an L-shaped terminal portion to which an end of the coil is connected and which comprises an one side portion from the terminal support portion toward a side of the circuit board and is connected to a circuit of the circuit board.
