At the same time, the rotation operating shaft member 25 is rotatably attached to the base plate 23 and integrally fixed to the stopper lever 24, and the shaft member 2
The spring 26 is wound around 5 and has both ends engaged with the bent portion 23a of the substrate 23 and the bent portion 24a of the stopper lever 24, respectively. The stopper lever 2 is normally operated by the urging force of the spring 26.
2 is biased in the direction of arrow A in FIG. 2 about the shaft portion 25 so that the bent portion 24a of the stopper lever 24 abuts on the stopper surface 23b of the substrate 23 and is positioned at the set position shown by the solid line in FIG. It is like this.

The shaft member 25 has a pair of flat surface portions 25 facing each other, as clearly shown in FIG.
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 portion of these surface portions 25a to 25d. Further, as shown in FIG. 5, the arcuate surface portion 25 d of the shaft member 25 is provided with an engaging groove 27 which is a concave groove extending in a direction orthogonal to the axis of the shaft member 25. A rotary operation knob 28 is attached to the tip portion.

The above-mentioned rotary operating knob 28 is made of a synthetic resin integrally molded product, and on the surface side of the knob 28, a pair of concave portions 29a, 29b and these concave portions 29 are formed.
A knob 29c formed between a and 29b is provided. An identification mark 30 composed of a hemispherical recess is formed on the front end surface of the knob 29.

A tubular fitting portion 31 is integrally formed in 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 tip portion of the shaft member 25, and as shown in FIG. 6, each pair of flat wall portions 31a, 31b facing each other.

An elastic engaging portion 38 formed of the elastic piece 34 and the engaging projection 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, and the fitting portion 31 of the knob 28 is placed under that state.
Is pushed toward the shaft member 25. With this,
By the slidable contact action between the inclined surface 35 of the elastic piece 34 of the fitting portion 31 and the arcuate wall portion 25d of the shaft member 25, the elastic piece 34 is elastically deformed outward as indicated by a dashed line in FIG. When the engaging projection 37 of the piece 34 reaches the engaging groove 27 of the shaft member 25, the engaging projection 37 is click-engaged with the engaging groove 27 as shown by the solid line in FIG. As a result, the knob 28 is prevented from slipping off and rotating from the shaft member 25.
It is assembled to 5 in one.

When the knob 28 is detached from the shaft member 25, the upper end of the knob main body 28a is pushed from the front side with a finger, or the lower end is pulled from the rear side by a finger, whereby the knob main body 28a is pulled. 9 is forcibly elastically deformed so as to incline with respect to the axial center of the fitting portion 31 and the shaft member 25 as shown by the dashed line in FIG.
The engaging protrusion 37 of No. 8 may be removed from the engaging groove 27 of the shaft member 25, and the knob 28 may be pulled out from the shaft member 25.

On the other hand, the above-mentioned shaft member 25 and knob 2
8 is normally arranged at a predetermined rotation initial position by the urging force of the spring 26, and accordingly, the stopper lever 24 is arranged at a set position shown by a broken line in FIG. This allows the windshield 4
The slider 5 supporting the above is locked at the intermediate height position by 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 being regulated.

Specifically, if the regulator handle 7 is rotated while the slider 5 is at the upper end position (top dead center position H), the slider 5 is guided and lowered by the guide rail 3. When the slider 5 reaches the position where the stopper lever 24 of the stopper assembly 22 is arranged,
The base portion 5a of the slider 5 contacts the stopper surface 40 of the stopper lever 24 as shown in FIGS. 2 and 4, and further lowering of the slider 5 is prevented. As a result, the window glass 4 has a top dead center position H (fully closed position) and a bottom dead center position L.
It is locked at an intermediate position M between (full open position). Therefore, normally, the window glass 4 can freely slide between the top dead center position H and the intermediate position M.

When it is desired to forcibly lower the window glass 4 beyond the intermediate position, the knob 29c of the rotary operation knob 28 is pinched and rotated.
The rotary operation shaft member 25 and the stopper lever 24 are rotated in the direction of arrow B in FIG. 2 against the biasing force of the spring 26 to be arranged at the position indicated by the chain double-dashed line. Along with this, the stopper surface 40 of the stopper lever 24 is moved to a position deviated from the movement path of the slider 4, so that the slider 5 and the window glass are rotated in response to rotational operation of the regulator handle 7 under such a condition. 4 can be further lowered from the intermediate position M and moved to the bottom dead center position L (fully open position).

Thereafter, when 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 makes sliding contact with the inclined surface 41 (see FIG. 2) of the stopper lever 24 and presses it. The stopper lever 24 is rotated in the direction of arrow B in FIG. 2 against the biasing force of the spring 26. Then, when the base portion 5a gets over the inclined surface 41, the stopper lever 24 is returned by the biasing 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. By this, the window glass 4 is reset to the state where it is prevented from descending at the intermediate position M.
