Patent ID: 7151333

Claim:
An actuator comprising: a stator assembly comprising: a pair of stator yokes each having a plurality of pole teeth at an inner circumference thereof, and a coil comprising a wound magnet wire, the coil being disposed between the pair of stator yokes; a rotor unit comprising a magnet at an outer circumference thereof, the rotor unit being disposed inside the stator assembly such that the magnet opposes the pole teeth of the stator assembly with a gap therebetween; an output shaft disposed inside the rotor unit; a housing; a front plate disposed between the stator assembly and the housing; a printed board having a land portion leading to a grounding wire; and a grounding terminal having electrical conductivity and elasticity, the grounding terminal being disposed between the stator assembly and the housing such that: one end portion of the grounding terminal makes contact with one stator yoke of the pair of stator yokes, the one stator yoke being located closer to the housing; and the other end portion of the grounding terminal makes connection to the land portion of the printed board.
