Abstract

PURPOSE:To incoporate a sensor and make driving control easy, by a method wherein a sensor to detect working speed and region of a motor is disposed within a gear case of a worm reduction gear to take output and at anti-load side of output shaft of the worm mechanism. CONSTITUTION:A worm 4 is attached to rotating shaft of a motor, and power is transmitted from output shaft 7 mounted on a worm wheel 6 engaged with the worm 4. A sensor gear 10 is connected to anti-load side of the output shaft 7 through a pinion 16. The sensor gear 10 is provided with two sensors 8 rotating concentric with the sensor gear, and a sensor pattern 24 is opposed to the sensor gear 10 and the sensor is slided on the sensor pattern 24. Such sensor mechanism is enclosed within a gear case 9 of a worm reduction gear, and signal is detected through lead wires 30 at both ends of the sensor pattern 24.
