  • Patent number: 7627989
    Abstract: A drive device for a wire-type window regulator is disclosed wherein a drum is accommodated in a cover and, under such a status, rotating and operating a rotation operator, exposed to an operation bore portion, enables work to be done for winding a wire. With the rotation operator kept in engagement with operation bore portion, the drum is avoided from rotating in a rewinding direction, making it easy to perform work for an output shaft of a motor to be brought into engagement with a drive bore portion of the drum.

  • Patent number: 6546672
    Abstract: A cable guide structure for a window regulator is provided with rails aligned so as to be parallel with each other, moving elements for supporting a window panel, a cable connected to said moving elements. A diagonally cabling portion of the cable is linearly arranged. The directions of tangent lines of the pulleys at contact points of rail cabling portions with cable guide grooves coincide with axial directions of a cable in the rail cabling portions respectively. Further the directions of tangent lines of pulleys at contact points of the diagonally cabling portion with the cable guide grooves coincide with an axial direction of the cable in the diagonally cabling portion.
