PURPOSE:To facilitate the manufacture of motor actuators which transmits the torque of a motor to an output shaft through a gear transmission device, by providing a switch board associated with an output gear on the output shaft, and by providing a conductor plate between the switch board and the output gear. CONSTITUTION:A motor 60 is secured to the support wall section 51 of a casing 50, and the output shaft 62 of the motor is fixed thereon with a worm 64, the power of the motor 60 may be transmitted to an output shaft 65 through a gear transmission mechanism A composed of a worm 64, a worm gear 68, gears 70-72 and the like. Further, a shaft side boss 75 is fixed to the output gear 65 at a position below an output gear 74, and a plate side boss 76 is provided rotatably on the output shaft 65 below the boss 75, and a switch board 77 is rotatably provided below the boss 76. Further, the casing 50 is attached at its bottom with a conductor plate 82 which is disposed between the output gear 74 and the switch plate 77. Further, first and second switch mechanisms B, C are arranged on both upper and lower surfaces of the conductor plate 82. |
