Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting structure for a window glass lifting guide rail that guides the window glass of an automobile window up and down.

Prior Art A window glass lifting guide rail for an automobile window is explained by taking a door glass as an example of the window glass. For example, as shown in Japanese Utility Model Application Publication No. 1976-1976, the upper end of the guide rail is attached to the side surface of the door inner panel. The lower end of the guide rail is fixed to the bottom wall of the door body, and the lower end of the guide rail is attached using a stud bolt that penetrates the bottom wall of the door body and is secured by tightening a nut. This will be explained in detail with reference to FIGS. 1 and 2. Reference numeral 1 indicates a door glass elevating guide rail made of pipe material disposed inside the door body 2. A glass holder 3 that is fixed and moved up and down by a window regulator is slidably fitted (both the door glass and the window regulator are not shown). The upper end of the guide rail 1 is fixed to the door inner panel 5 with a bracket 4, and the lower end is fixed to the door inner panel 5 by inserting a stud bolt 6 fixed to the lower end of the guide rail 1 into a mounting hole 8 provided in the bottom wall 7 of the door body. It is fixed by tightening a nut 9 on the lower surface side of the bottom wall 7. Stud bolt 6 is head 6
a is press-fitted and fixed to the lower end of the guide rail 1. Further, the head 6a of the stud bolt 6
A rubber washer 10 is interposed between the door body bottom wall 7 and the door body bottom wall 7 to prevent the nut 9 from loosening. Note that 11 indicates a metal washer for holding down the rubber washer 10.

However, in such a conventional structure, depending on the tightening of the nut 9, the washer 11 and the bottom wall 7 of the door body
Since the amount of compressive deformation of the rubber washer 10 changes between the two, it is difficult to obtain a sense of moderation when tightening the nut, and it is easy to overtighten the nut 9. Also, due to the influence of significant temperature changes inside the door body 2, the rubber washer 10 is damaged prematurely. Not only is there a problem in that the nut 9 loses its locking function due to sagging, but also the rubber washer 10 will fall off the stud bolt 6 if it is not held by hand, making the installation work troublesome. It was hot.

Purpose of the Invention In view of the conventional situation, the present invention provides a window glass elevating guide rail that can reliably prevent the rubber washer from becoming loose due to over-tightening of nuts, has excellent installation workability, and has a simplified configuration. The purpose is to provide a mounting structure for.

Structure of the Invention In order to achieve the above-mentioned object, in the present invention, the window glass lifting guide rail is made into a pipe shape, the head of a stud bolt is fixed to the lower end of the guide rail, and a rubber washer is inserted into the stud bolt to fix the stud. In a structure in which a bolt passes through the bottom wall of the vehicle body and is fixed by tightening a nut, the head of the stud bolt is located at the lower edge of a cut-out formed inwardly and downwardly on the peripheral wall of the guide rail. The guide rail is welded to the stud bolt, and the guide rail is provided with an extending portion below the head of the stud bolt, and the rubber washer is elastically mounted between the stud bolt and the extending portion, and the thickness of the rubber washer is equal to the thickness of the extended portion. It is formed to protrude a predetermined amount from the end of the section.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals assigned to the same parts as in the conventional structure.

That is, in this embodiment, taking a door glass as an example of the window glass, as shown in FIG. is fixed by welding to the peripheral wall of the guide rail 1 by engaging with the lower edge of a cut-out 12a formed facing inward and downward, and a rubber washer 10 is attached to the stud bolt 6.
A, the stud bolt 6 is passed through a mounting hole 8 provided in a bottom wall 7 of a door body 2 serving as a vehicle body, and is fixed by tightening a nut 9 on the lower surface side of the bottom wall 7, and the stud bolt 6 is attached to the guide rail. 1 stud bolt 6
An extending portion 1a is provided below the head 6a of the bolt, and a rubber washer 10A is elastically mounted between the stud bolt and the extending portion 1a, and the thickness of the rubber washer 10A is adjusted so that it protrudes by a predetermined amount from the end of the extending portion 1a. It is formed in 12 is an opening created by forming the cut and raised portion 12a.

In this embodiment, the guide rail 1 is extended downward from the head 6a of the stud bolt 6, and this extended portion 1a constitutes a stopper 20 for regulating compressive deformation of the rubber washer 10A. Further, the rubber washer 10A is inserted into the extended portion 1a until it hits the bolt head 6a, and is formed to have a thickness such that it protrudes from the end of the extended portion 1a by a predetermined amount, and the periphery of this projected end is compressively deformed. It is chamfered so that it does not protrude outward when it is opened. Further, this rubber washer 10A is mounted between the stud bolt 6 and a stopper 20, and this stopper 20 also functions as a holder for the rubber washer 10A.

According to the above embodiment structure, the stud bolt 6
into the mounting hole 8 of the bottom wall 7 of the door body and insert the nut 9
When tightened, rubber washer 10A will stop at stopper 20.
When the rubber washer 10A is compressively deformed by the amount of protrusion from the end edge, the end edge of the stopper 20 abuts against the bottom wall 7 to restrict the compressive deformation of the rubber washer 10A. Therefore, it is possible to reliably prevent the rubber washer 10A from becoming loose due to over-tightening of the nut 9, and the end edge of the stopper 20 abuts against the bottom wall 7, providing a sense of moderation in the nut-tightening work, allowing the operator to tighten the nut 9. You can feel that you have concluded the terms to the fullest. Furthermore, as mentioned above, the stopper 20 is connected to the rubber washer 1.
Since it also serves as a holder for 0A, when installing the guide rail 1 inside the door body 2, the rubber washer 10
There is an advantage that A does not need to be held by hand. In the conventional type shown in FIGS. 1 and 2, the washer 11 and rubber washer 10 are attached to the stud bolt 6.
Compared to the case where the stud bolt 6 had to be held by hand until it is inserted into the mounting hole 8 to prevent it from falling out, the assembly work is much easier to assemble, and the worker is not forced into an unreasonable posture. This has the advantage that work efficiency can be greatly improved since there is no

As mentioned above, the stud bolt 6 has its head 6
a is welded to the circumferential wall of the guide rail 1 by engaging with the lower edge of the cut-out 12a formed inwardly and downwardly, so that the lower edge of the cut-out 12a is attached to the head of the stud bolt 6. There is an advantage that the stud bolt 6, which functions as a positioner for the portion 6a and is related to the amount of compression of the rubber washer 10A, can be easily positioned.

Effects of the Invention According to the present invention, the extending portion of the guide rail constitutes a stopper disposed on the outer periphery of the rubber washer, and this stopper restricts the compressive deformation of the rubber washer to a certain constant amount. It prevents the nut from becoming loose and fully demonstrates its locking function, and the contact between the stopper and the bottom wall of the door body provides a sense of control when tightening the nut, ensuring that the nut can be tightened reliably. There are advantages. In addition, the stopper also functions as a holder for the rubber washer, and the rubber washer can be sub-assembled without falling off the stud bolt, which further improves guide rail installation workability. Since the stopper is formed by a built-in part, a separate part as a stopper is not required, which simplifies the configuration and simplifies parts management. Furthermore, the head of the stud bolt is welded to the peripheral wall of the guide rail by engaging the lower edge of the cut-out that is formed facing inward and downward, making it easy to position the stud bolt. It has a great effect.
