<P>PROBLEM TO BE SOLVED: To provide an actuator that efficiently achieves reduction in size and weight while reducing an influence of electromagnetic noise on a control board even when a motor casing is molded of resin. <P>SOLUTION: The actuator 1 includes: an electric motor, a control board for controlling the drive of the electric motor, a resin-made motor casing which houses the electric motor and the control board, a transmission mechanism which is linked to the rotating shaft of the electric motor, and a conductive gear casing 7 which houses the transmission mechanism. The gear casing 7 is provided with an output shaft which is rotatable, and the torque of the electric motor is transmitted to the output shaft through the transmission mechanism. A conductive base plate 8, which is formed to support one part of the transmission mechanism and one end of the rotating shaft, is provided between the motor casing and the gear casing, and the base plate 8 and the control board are electrically connected with each other, and the base plate functions as a ground plate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
