2 is urged in the direction of arrow A in FIG. 2 around the shaft portion 25 so that the bent portion 24a of the stopper lever 24 comes into contact with the stopper surface 23b of the substrate 23 and is positioned at the set position shown by the solid line in FIG. It has become.

As shown in FIG. 5, the shaft member 25 has a pair of flat surface portions 25 facing each other.
a, 25b and a pair of arc-shaped surface portions 25 facing each other
c, 25d and a cylindrical portion 25e which is a base of these surface portions 25a to 25d. As shown in FIG. 5, an engagement groove 27 formed of a concave groove extending in a direction perpendicular to the axis of the shaft member 25 is provided on the arcuate surface portion 25 d of the shaft member 25. A rotary operation knob 28 is engaged with the distal end.

The above-mentioned rotary operation knob 28 is an integrally molded product made of synthetic resin, and a pair of concave portions 29a and 29b,

A tubular fitting portion 31 is integrally formed at the center of the back surface of the main body 28a of the knob 28. This fitting part 3
The one hollow hole 32 is formed so as to correspond to the size and shape of the distal end portion of the shaft member 25, and as shown in FIG. 6, a pair of flat wall portions 31a and 31b facing each other.
And arcuate wall portions 31c and 31d. Then, as shown in FIGS. 6 and 7, the above-mentioned fitting portion 31 is provided with a cutout portion 33 on the side of the arc-shaped wall portion 31 d,
The base of the arc-shaped wall 31d surrounded by the notch 33 is left to form an elastic piece 34. Further, an engagement protrusion 37 having an inclined surface 35 inclined toward the inside of the elastic piece 34 and a locking step surface 36 substantially perpendicular to the elastic piece 34 is integrally formed at the tip of the elastic piece 34. An elastic engaging portion 38 formed of the elastic piece 34 and the engaging protrusion 37 is integrally formed.

Thus, the rotary operation knob 28 is assembled to the rotary operation shaft member 25 as follows.
First, by positioning the identification mark 30 of the knob 28 upward, for example, the positioning (orientation) with respect to the shaft member 25 is performed.
Is pushed toward the shaft member 25. Along with this,
Due to the sliding contact between the inclined surface 35 of the elastic piece 34 of the fitting portion 31 and the arc-shaped wall 25d of the shaft member 25, the elastic piece 34 is elastically deformed outward as shown by a dashed line in FIG. When the engagement protrusion 37 of the piece 34 reaches the engagement groove 27 of the shaft member 25, the engagement protrusion 37 is click-engaged with the engagement groove 27 as shown by a solid line in FIG. As a result, the knob 28 is prevented from coming off and rotating from the shaft member 25 while the shaft member 2 is stopped.
5 is integrally assembled.

When the knob 28 is detached from the shaft member 25, the upper end of the knob main body 28a is pushed with a finger from the front side, or the lower end is pulled with a finger from the rear side, and the knob main body 28a is removed. 9 is forcibly elastically deformed so as to be inclined with respect to the axis of the fitting portion 31 and the shaft member 25 as shown by a chain line in FIG.
The engagement protrusion 37 of the shaft 8 may be removed from the engagement groove 27 of the shaft member 25, and the knob 28 may be pulled out of the shaft member 25.

On the other hand, the aforementioned shaft member 25 and knob 2
8 is normally arranged at a predetermined initial rotation position by the urging force of the spring 26, and accordingly, the stopper lever 24 is arranged at a set position indicated by a broken line in FIG. Thereby, the window glass 4
Is locked at the intermediate height position at the stopper surface 40 of the stopper lever 24, the window glass 4 is lowered to the bottom dead center position L, and the window opening 2 is not fully opened. Is regulated as follows.

[0022] Specifically, the slider 5 when rotating the regulator handle 7 when in the upper end position (top dead center position H), the slider 5 is lowered while being guided by the gas Idoreru 3. When the slider 5 reaches the position where the stopper lever 24 of the stopper assembly 22 is disposed,
The base portion 5a of the slider 5 is in contact with the stopper surface 40 of the stopper lever 24 as shown in FIGS. 2 and 4, the substrate 23
Stopper surface 23b and bent portion 24 of stopper lever 24
a due to the contact action (stopper action) between the slider 5
Is prevented from falling further. As a result, the window glass 4 is held at an intermediate position M between the top dead center position H (fully closed position) and the bottom dead center position L (fully opened position). Therefore, in the normal state, the window glass 4 is at the top dead center position H and the intermediate position M.
It is possible to slide freely between and.

The window glass 4 is moved to the intermediate position M
When it is desired to forcibly lower the rotation operation knob 28, the knob 29c of the rotation operation knob 28 is pinched and rotated to operate the rotation operation shaft member 25 and the stopper lever 2.
4 is rotated in the direction of arrow B in FIG. 2 against the urging force of the spring 26 to be disposed at the position shown by the two-dot chain line. Accordingly, the bent portion 24a of the stopper lever 24
Since the stopper surface 40 of the stopper lever 24 is moved to a position deviated from the movement path of the slider 4 while the stopper surface 23b of the substrate 23 is separated from the stopper surface 23b , the regulator handle 7 is rotated in such a state. As a result, the slider 5 and the window glass 4 can be further lowered from the intermediate position M and moved to the bottom dead center position L (fully open position).

Thereafter, as the rotation operation of the rotation operation knob 28 is released, the stopper lever 24 is returned by the urging force of the spring 26. When the slider 5 is raised by rotating the regulator handle 7 in such a state, the base portion 5a of the slider 5 slides on and presses the inclined surface 41 (see FIG. 2) of the stopper lever 24. The stopper lever 24 is turned in the direction of arrow B in FIG. 2 against the urging force of the spring 26. When the base portion 5a gets over the inclined surface 41, the stopper lever 24 is moved back by the urging force of the spring 26, and the bent piece 24a of the stopper lever 24 is engaged with the stopper surface 23b of the substrate 23. Thereby, the window glass 4 is set again in a state where it is prevented from descending at the intermediate position M.

The window regulator 2 having the above configuration
According to 1, the stopper assembly 22 is mounted on the guide rail 3 and the rotary operation type stopper lever 24 is arranged in the movement path of the slider 5, so that the window glass can be used without using operating members such as rods and wires. 4
In addition to the configuration of the stopper mechanism, the number of parts and the number of assembling steps are small, and the assembling operation can be easily performed. Therefore, the configuration can be made very simple and inexpensive. Moreover, the operating means of the stopper lever 24 is the knob 28
There is also an advantage that the operation is very easy because of the rotation operation type.

As described above, one embodiment of the present invention has been described.
The present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention. For example, the shape of the stopper lever 24 and the slider 5, the stopper lever 24 and the rotation operation shaft member 25.
