[Prior art and its problems]
Conventional wire type window regulators have fixed front and rear guide rails that guide the front and rear ends of the window glass to the door panel, and the front and rear guide rails support the lift pieces that are lifted and lowered by the drive wires, respectively. The basic structure of fixing the lifting piece to the window glass was provided. The front and rear guide rails are required to have a parallelism that matches the width of the window glass and a curvature that matches the curvature of the window glass. Further, since the drive system including the drive wire is supported on a bracket fixed to the door panel separately from the front and rear guide rails, matching with the front and rear guide rails (and the lifting pieces) is indispensable.
[0003]
In addition, these front and rear guide rails and drive system support brackets must be inserted between the outer panel and the inner panel through the work holes drilled in the inner panel that constitutes the vehicle door. This was a cause of reducing the strength of the door panel.

On the arm member 20, an overhang portion 25 on which the forward / reverse winding drive device 40 is mounted is formed in the middle of the pivot portion 30 and the guide pulley 21. The forward / reverse winding drive device 40 supported on the overhanging portion 25 includes a winding drum 41 rotatably supported in a shaft hole 25a formed in the overhanging portion 25, a cover member 42 of the winding drum 41, And a motor drive unit 43 located on the opposite side of the winding drum 41 and the cover member 42 with respect to the arm member 20. The motor drive unit 43 includes a worm 43b that is rotated forward and backward by a forward / reverse drive motor 43a, a worm wheel 43c that meshes with the worm 43b, and a worm wheel 43c that is coaxially integrated with the shaft hole 25a and inserted into a winding drum. And a rotation shaft 43d coupled to 41 so as not to be relatively rotatable. Therefore, when the worm 43b is driven to rotate forward and backward by the forward / reverse drive motor 43a, the winding drum 41 rotates forward and backward.
[0011]
A drive wire 45 is wound between the guide pulleys 11 and 12, the guide pulleys 21 and 22, and the winding drum 41. The drive wire 45 is located between the guide pulleys 11 and 12, and between the guide pulleys 21 and 22, and between the guide pulleys 11 and 22, and between the guide pulleys 21 and 22 And a pair of substantially parallel upper and lower portions 45B located in the vertical direction.
[0012]
The drive wires 45 are divided at the front and rear substantially parallel vertical portions 45B, and the divided edges are joined by a pair of front and rear sliders (joining members with window glass) 46, respectively. 2, 6, and 7, the drive wire 45 has a retaining protrusion 45 </ b> C at the dividing edge on the slider 46 side, and the retaining protrusion 45 </ b> C is in the retaining recess 46 a of the slider 46. Is detachably fitted.
[0013]
Of the pair of drive wires 45 (vertical portion 45B) that protrudes from the front slider 46, the drive wire 45 guided (upward) to the guide pulley 11 reaches the guide pulley 12 via the arm portion 45A. , Coupled to the rear slider 46. Further, the drive wire 45 that has come out of the front slider 46 and led (downward) to the guide pulley 22 is wound around the winding drum 41 of the forward / reverse winding drive device 40 through the arm portion 45A along the arm member 20. Has been. Further, the drive wire 45 guided (upward) from the rear slider 46 to the guide pulley 21 is wound around the winding drum 41 of the forward / reverse winding drive device 40 via the arm portion 45A of the arm member 20. Yes.
[0014]
That is, in this embodiment, the drive wire 45 is divided into three (one wire for connecting the front and rear sliders 46 and two wires extending between the front and rear sliders 46 and the take-up drum 41). Thus, they are coupled together as a series of drive wires. When the drive wire 45 is wound in this way, when the drive wire 45 is moved in either direction, a pair of substantially parallel vertical portions 45B in front and rear are simultaneously moved in the same direction. Of course, it is possible to connect the slider 46 to the series of drive wires 45 without dividing the drive wire 45 at the slider 46 portion. However, when the drive wire 45 is divided as shown in the drawing, the drive wire 45 is separated at the slider 46 portion later. Can be combined.
[0015]
