ABSTRACT:
An ultrathin transmission mechanism for all types of automobile power windows is provided, in which the gears thereof each is formed at its shaft hole periphery with two laterally outward projected flanges for positioning the gears on the transmission mechanism with reduced overall width or thickness required for mounting the transmission mechanism. A transmission chain thereof is partially coated at its cord segments exposed between every two ball-type teeth with a layer of material the same as that used to make the ball-type teeth, thereby preventing the transmission chain from becoming extended even after a long term period of use and to always provide high-precision displacement.
