Abstract

PROBLEM TO BE SOLVED: To avoid deformation due to a load produced during the movement of an inner cable and to simplify a process for providing a retainer mounting part by providing a bush part on that side of the retainer which faces a guide pulley, providing each bracket plate with a raised piece, and fitting and supporting the retainer inside a recess in the end of the raised piece. SOLUTION: An outer cable 17 is supported at its ends on upper and lower bracket plates 15 via a retainer 30. Both ends 12b of an inner cable which are projected toward a guide pulley 19 from the retainer 30 are supported on a guide recess 31a in a raised piece 31 via a bush part 36. Because the retainer 30 has its front wall part made to abut to the raised piece 31, the retainer 30 is pressed against the raised piece 31 by means of both a load produced by the movement of the end 12b and the pressing force of the flat steel wire of the outer cable 17. Therefore, destruction due to compressive loads is unlikely to occur, and the retainer 30 causes no creep deformation around the inner cable. A process for a mounting part can thus be simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire supporting device of a window glass lifting mechanism for lifting a window glass of a vehicle or the like.

[0002]

2. Description of the Related Art For example, a window glass raising / lowering mechanism for raising and lowering a window glass of an automobile supports a slider base for supporting the window glass on a guide rail supported by a reinforcing member of a door so as to be vertically movable, Both ends of the wire are connected to the slider base and wound around guide pulleys above and below the guide rail, and then the middle portion of the wire is wound around a winding drum. In the window glass lifting mechanism having such a configuration, when the winding drum is rotationally driven manually or the like, one of both ends of the wire is wound and the other is released, whereby the window glass is moved up and down.

By the way, the wire is actually composed of an outer cable and an inner cable which is inserted into and retractable from the outer cable, and both ends of the outer cable are located at upper and lower ends of the guide rail. The pair of fixed bracket plates are supported via retainers at positions facing the respective guide pulleys. The inner cable projecting from the outer cable to the guide pulley side through the projecting hole of the retainer is wound around the guide pulley as described above and then fixed to the slider base.

In a window glass lifting mechanism for moving an almost endless inner cable in the upper and lower parts in opposite directions by winding it on a winding drum, for example, the inner cable is attached to the lower bracket plate and the inner cable is attached to the outer cable. When pulled into the cable, the inner cable is pushed out from the outer cable toward the guide pulley on the retainer side fixed to the upper bracket plate, and the load and the pressing force of the outer cable that tries to move in the same direction are It acts around the inner cable protrusion of the retainer. On the contrary, when the inner cable is pulled into the outer cable on the upper retainer side, the inner cable is pushed out from the outer cable toward the guide pulley on the lower retainer side, and the load and the outer cable trying to move in the same direction cause it. The pressing force acts around the inner cable protrusion of the lower retainer. Therefore, the retainer made of a synthetic resin material may cause creep deformation around the protrusion in some cases when the load or stress is applied to the retainer, the deformation of the material increases with time.

Further, since the window glass elevating mechanism has a separate mounting portion for mounting the retainer on the bracket plate, a step for providing the mounting portion is required separately from the processing steps for the respective portions. Such a process
It is preferable to reduce even one because it leads to cost reduction.

[0006]
