PURPOSE:To open/close a window glass into a desired opening instantaneously by providing a magnetic plate provided with slit which rotates together with the output shaft of a motor and a proximity switch opposing to the slit. CONSTITUTION:An opening/closing switch 4, a drive part 2 operated by the signal of the switch, a carrier plate 7 fixed to a window glass W, and a guide rail 8 to guide the movement are provided. Next, a control cable 6 is laid around the drive part 2 and the carrier plate 7. A magnetic plat provided with slit which rotates together with the output shaft of an electric motor 9 and a proximity switch arranged opposite to the slit are provided on the drive part 2. By operating the switch 4 so as to select a desired opening, the signal is input to a control box 3, and the motor 9 is operated. Next, when the rotated quantity of the drive part 2 is detected by the proximity switch and it reaches the quantity corresponding to the opening of the window glass W, operation of the motor 9 is stopped. |
