Claim:
A wire window regulator comprising: a motor serving as a drive source; a drum having an outer periphery formed with a recess in which a wire is wound; a cover having a top surface and an inner wall, formed in a circular shape in cross section, by which a drum accommodating space is defined, wherein under a condition where the drum is accommodated in the drum accommodating space, the wire is wound between the inner wall and the recess of the drum to prevent dropout of the wire; a drive bore portion, formed in a bottom surface of the drum at a rotational axis thereof, which has a shape to correspond to a cross-sectional shape of an output shaft of the motor, said output shaft operatively received in said drive bore portion; a rotation operator formed at a rotation center of a top surface of the drum, an inner wall of the rotation operator having a polygonal shape in cross section; and an operation bore portion formed in the top surface of the cover such that under the condition where the drum is accommodated in the cover, the rotation operator is exposed to an inside of the operation bore portion, a diameter of the rotation operator being smaller than a diameter of the operation bore portion; wherein a rotary shaft, which has a polygonal shape in cross section in conformity with the cross-sectional shape of the inner wall of the rotation operator, inserted through the operation bore portion toward the inside of the cover and kept in a fixed condition.
