A window regulator assembly including a shaft (12) having a pinion gear (14) and a counter balance spring (16) mounted on the shaft which winds or unwind as the shaft rotates. A spring housing (20) is mounted on the shaft. A cable - guiding drum (24) having an inner gear (26) is driven directly by the pinion gear, as the drum has a rotational axis that is offset from a rotational axi s defined by the shaft, thus providing mechanical advantage. A casing (28) houses the spring (16), spring housing (20) and the drum (24) in abutting relationship. A guide such as a rail (42) is disposed on at least one of the spring housing and the drum for maintaining rotational alignment of the drum relative to the shaft. |
