  • Patent number: 8209907
    Abstract: A window regulator includes a wire sag compensating mechanism. The wire sag compensating mechanism includes an outer tube arranged between the vicinity of a drum and at least one wire guide member allowing passage of a wire therethrough and fixed at an end on the side of the wire guide member to a member where the wire guide member may be provided. A tube holding portion may be provided on a member on which the drum is provided allowing movable engagement of the drum side of the outer tube and guiding the drum side of the outer tube in the axial direction of the outer tube. A spring may be provided for urging the drum side of the outer tube away from the drum. A disengagement restricting arrangement (e.g., projections and elongated holes) may be provided for restricting the outer tube from disengaging from the tube holding portion.

  • Patent number: 8127496
    Abstract: In a window regulator 10, when a pin bolt 42 provisionally attached to a pulley 22 and a pulley support 54 is fastened to a door panel 14 by a nut 52, the pulley 22 and the pulley support 54 are supported on the pin bolt 42 and attached to a predetermined position on the door panel 14. Here, in the above-described provisionally attached state, the pin bolt 42 is held in the pulley 22 by pin member holding claws 74 of the pulley 22, and the pulley 22 is held in the pulley support 54 by pulley holding claws 68 of the pulley support 54. Consequently, when the pin bolt 42 is to be fastened to a body panel, the pulley 22, the pulley support 54, and the pin bolt 42 can be handled as a single part. Thus, the work of attaching a pulley and a pulley support to a body panel of a vehicle can be facilitated.

  • Patent number: 7547060
    Abstract: To a pair of link arms, portions of a fitting mechanism that can be engaged with each other in a vehicle width direction are formed. Further, hinge bases that hold both ends of the pair of link arms rotatably can fit together in the vehicle width direction. By this structure, when a load is applied onto a sliding door from the outside of the vehicle owing to a side collision or the like, and a force is applied onto the fitting mechanism and the pair of hinge bases in the vehicle width direction and in the vehicle vertical direction, the portions of the fitting mechanism and the pair of hinge bases fit together, and the movement of the link arms to the upper side in the vehicle vertical direction is regulated. Thereby, the pulling deformation of the sliding door to the inside of the vehicle body is suppressed.
