Abstract
A driver unit for a window regulator or winder for use in an automobile door, for example, includes a gear rotatably mounted on a base and having first and second shafts coaxial with each other and projecting from opposite sides of the gear, the first shaft being rotatably supported on said base, the gear having a support coaxial with the first and second shafts and a plurality of angularly spaced arms projecting radially outwardly from the support. A drum is rotatably mounted on the second shaft and has a plurality of angularly spaced cavities opening toward the support. A plurality of integrally joined dampers are disposed as pairs in the cavities, respectively, with one of the arms being interposed between the dampers in each pair. The gear is rotated by a motor mounted on the base to rotate the drum through the arms and the dampers to move a wire wound on the drum and coupled to the window glass for thereby moving the window glass in the automobile door.
