Abstract: A transmitting chain for an automobile electric window includes an endless transmitting chain, a lower gear, an upper gear, two lower chain protectors, two upper chain protectors, two elastic tubes and an elongate cover. The lower chain protectors contain the lower gear having a leaf connector to combine with a rotating mechanism, which rotates the lower gear. The lower gear then moves the chain, which then rotates the upper gear. The upper gear then moves a lowering and lifting mechanism of the electric window of an automobile. The endless chain has its two intermediate portions contained in the elastic tubes and the elongate cover covers the tubes to hold them side by side.

Abstract: A transmitting device for an automobile electric window consists of a housing, a motor, a worm gear, a cap, an elastic shaft connector, a lower chain protector, and an upper chain protector combined together. The motor has a worm on its shaft to rotate the worm gear placed in the housing, and the worm gear is connected with the elastic shaft connector connected with a leaf shaft of the lower chain protector. An endless chain extends around the leaf shaft and a gear in the upper chain protector, which is rotated by the chain through the motor, the worm gear, the elastic shaft connector, the leaf shafts so as to lower and lift an electric window of an automobile.
