ABSTRACT:
A drive apparatus includes a commutator motor having a hollow rotation shaft with an internally threaded section provided therein and a flexible power transmission cable inserted through the hollow rotation shaft such that a spiral thread-like rib of the cable engages with the internally threaded section of the hollow rotation shaft, whereby a propulsive force is transmitted to the cable to allow a window glass to be moved in a reciprocating motion. A guide roller with an intermediate section of the cable wrapped therearound is rotatably supported on a guide base to allow the passage of the cable. A curved guide section is provided relative to the guide roller to define a curved cable passage channel in a manner to cover a wrapped cable portion. The guide roller is rotated by the commutator motor through the cable, while the intermediate portion of the cable is pressed onto the guide roller.
