Window regulator having spring biased cable drums

A window regulator comprising:

• a motor assembly including a drive housing and a power motor;
• a drive shaft rotatably driven by said power motor, said drive shaft including a center shaft and a key shaft spaced therefrom;
• a pair of cable drums each having a central bore receiving said center shaft and a key slot aligning with and receiving said key shaft therethrough;
• a cable having a first end connected to one of said cable drums and at least partially wound around said one of said cable drums in a first direction and a second end connected to said other of said cable drums and at least partially wound around said other drum in a second direction opposite said first direction;
• and
• a coiled spring mounted between said cable drums about said center shaft, said spring having a loop formed therein receiving said key shaft and projecting spring tabs abutting said drums for biasing said drums in opposite directions and maintaining tension on said cable between said first and second ends.
