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.
