Reference numerals 8 denote an upper frame and a lower frame provided inside the door panel 1, and are fastened to corresponding mounting portions at the door panel position by arbitrary fasteners such as bolts. Code 50
Denotes a guide rail, and upper and lower ends thereof are also fixed to the upper frame 7 and the lower frame 8, respectively. The fixing is performed using, for example, a well-known bracket hardware 51 or the like. The drive mechanism 18 for driving the carrier plate 14 up and down is connected to the guide rail 50.

Next, as shown in FIG. 1, the window glass 25 is normally curved so that the outside of the vehicle is bulged.
Move up and down toward. In a sashless type such as a hard-top car, the upper end 26 of the glass is in contact with the receiving part 24 of the car body, and it is free toward the outside,
When a strong suction force is applied, the upper end receives a large suction force in the outdoor direction 19a. The window glass 25 has a connecting portion 27 at the bottom. The structure of the connection is shown in detail in FIGS.

Next, the guide rail 50 will be described. As shown in FIGS. 5 and 6, the guide rail 50 has a U-shaped free end directed inward as shown in FIGS. 5 and 6, and is generally called a C-shaped steel. Therefore, as shown in FIG.
A streak-shaped opening 54 is formed between the bent portions 53. The guide rails 50 are arranged in the vertical direction of the door panel so as to correspond to the vertical movement locus of the window glass 25.

Next, in the guide rails 50 shown in FIGS. 3 to 6, reference numeral 59 pushes up the shoe 30b to the opening 54 side of the guide rail 50 when the window glass 25 reaches the upper limit position shown in FIG. FIG. This projection 59
Is provided on a part W2 of the entire width W1 of the bottom surface 50b of the guide rail 50. The width of W2 is equal to or smaller than the width of the opening 54, and a gap 59a is provided on both sides W3. As shown in FIG. 3, the bulging height of the projection 59 is set to a height that can be raised by pushing up the sliding member 36 so as to generate a sufficient reaction force against the force of the connecting rod 40 in the direction of the arrow 19. The position of the protrusion 59 may be on both sides of the bottom surface indicated by W3 in FIG. 6, or may be a shape protruding toward the center from both side walls of the guide rail 50 as shown in FIG. You may. A projection 59 that has been further widened to the width of W2
Since the opening 54 allows the opposing receiving die to be inserted toward the projection 59, the pressing die is applied from the outside of the guide rail 50 to easily expand the projection 59. Can make and process.

Next, 30 is a space for sliding the guide rail 50.
Shows a shoe for sliding 52 up and down, and guide rail 50
Is made of a slippery material, for example, a plastic material (eg, polyacetal, nylon, etc.). 3 to 6, the outer cover members 31a, 31
Each of b and 31c is plastically formed of an integral material, and a base member 32 of the metal connecting rod 40 is accommodated in an inner space. The lower member of the base member 32 shows an elastic body 34 having cushioning properties, for example, made of synthetic rubber or the like, and further below the lower body, that is, the sliding member 3 in contact with the bottom surface 50b of the guide rail 50.
Reference numeral 6 denotes a configuration as shown in FIGS. 4, 5, 6, 7, and 8, and is made of a slippery member (for example, polyacetal or nylon). In such a configuration, the surfaces sliding on the inner surfaces of the guide rails 50 are each formed of a slippery material such as plastic, so that they move up and down very smoothly. Next, the base member 32 at the base of the connecting rod 40
Is integrally formed of a metal material with the connecting portion 32b and the seat plate member 32a. Reference numeral 41 denotes a pressing member for pressing the glass 25, which has a female screw therein and is usually called a nut. Therefore, in assembling, the seat plate member 32a connected to the connecting rod 40 is pushed (or plastically integrally formed) into the inside of the jacket member 31 of the shoe 30, and then the elastic body 34 and the sliding member 36 are respectively attached to the shoe 30 in FIGS. Assemble as shown in 6. In this case, for the annular contact surface provided on the back surface of the elastic body 34,
An annular bulging portion 37 to bulge is applied to the surface of the sliding member 36. These are inserted from the end of the guide rail 50 to the inside. In this case, when there are a plurality of shoes 30 in the upper part and the lower part, these outer covering members 31 are connected to each other in advance by a connecting member 39 as shown in FIG. In addition, this linking member
The material 39 is a member 39 (for example, polyacetal, nylon or the like) having flexibility as long as the interval between the shoes can be kept constant, and is connected to the jacket member 31a by an integral plastic molding. The shape of the bulging portion 37 provided on the sliding member 36 is as follows.
In addition to the annular shape, a bulged portion having an arbitrary shape such as a pole-shaped bulged portion and a streak-shaped bulged portion that are extremely independent may be used.

Next, the shape of the surface of the upper shoe 30a facing the projection 59 of the guide rail 50 is such that the window glass 25 moves from the state of FIG. 1 to the state of FIG. Down and up, and vice versa. That is, the downward (or upward) in FIG.
In the state, the shoe 30a faces the protrusion 59. At this time, when the sliding surface 36c of the sliding member 36 collides with the projection 59, a large load is applied to the drive mechanism 18. But sliding members
As shown in FIG. 6, the shape of the protrusion 36 is such that a portion opposing the width dimension W2 of the protrusion 59 is concavely formed in a corresponding shape, and a cutout portion 36b is formed there. Therefore, when the shoe 30a passes through the location where the projection 59 is formed, the projection 59 relatively passes through the location of the notch 36b in the shoe 30a, and the projection 59 does not collide with the sliding member 36. When the projection 59 is provided at the location indicated by the reference symbol W3 or at the location shown in FIG. 7, the position of the notch 36b in the shoe 30a is selected to be a position corresponding thereto.

Next, the glass 25 having a plurality of holes 28 is attached to the shoes 30a, 30b while penetrating the heads of the connecting rods 40, 40, respectively. In that case, washers 45, 46 are provided on both sides of the glass 25.
Layer. This washer is preferably larger in size than the inner diameter of the hole 28, and the outer washer 45 is formed of a hard sheet metal, and the inner washer 46 is formed of a soft material capable of soft touch such as resin. In this case, as shown in FIG. 3, the female screw of the nut 41 and the male screw of the connecting rod 40 are screwed together with the carrier plate 14 interposed therebetween as shown in FIG. Then, the glass 25 and the shoe 30 are integrated via the rod-shaped connecting rod 40. Note that the width of the seat plate member 32a is set so that the tensile force of the seat plate member 32a in the direction of the window glass can be covered by the inner opening edge of the bent portion 53 of the guide rail as apparent from FIG. The width of the opening 54 is larger than the width of the opening 54.

Next, when there are large and small variations in the dimension W between the inner surface 50a and the bottom surface 50b of the guide rail 50 in the longitudinal direction, and when a pressing force is applied to the shoe 30, respectively. The operation of the shoe 30 will now be described. The state of the shoe 30a in FIG. 3 shows a case where the dimension W is an average dimension, and the two opposing surfaces of the elastic body 34 and the sliding member 36.
In a state where a gap G is formed between 34a and 36a, the head of the bulging portion 37 is lightly in contact with the contact surface 35. The resilience of the elastic body in that state is in a relatively small range. Next, the shoe shown in FIG.
In the state of 30b, the window glass 25 is in the state of FIG.
The drawing shows the state of the shoe when the suction force is applied to the lower shoe 30b of the upper and lower two shoes and a pressing force in the direction of arrow 19c can be generated. In this state, the connecting rod 40 receives a pressing force in the direction of the arrow 19c, and presses the elastic body 34 toward the sliding member 36. Then, the opposing surfaces 34a and 36a of the elastic body 34 and the sliding member 36
And the repulsive force of the elastic body is extremely large. As described above, the elastic body 34 and the sliding member 36 in the shoe 30 play the role of expansion and contraction, respectively, and adapt to the variation of the dimension W in the guide rail 50, and the inner surfaces of the shoe 30 and the guide rail 50 are adjusted. A gap is formed between them to prevent rattling and noise. Also, in the place where the projection 59 shown in FIG.
The upper edge 26 has a function of preventing the upper edge 26 from opening greatly outside the room.

[0016]

According to the present invention, the inner surface of the guide rail 50
In a state where the window glass 25 has reached the upper limit position, a projection 59 for pushing up the shoe to the opening 54 side of the guide rail 50 is provided, and when the window glass 25 has reached the upper limit position, the upper end 26 of the window glass is provided. Can be strongly pushed into the body side, so that the degree of close contact with the weather strip 24 is increased, and there is an effect that the wind glass 25 can be prevented from being sucked out to the outside of the vehicle and rain can be prevented. In addition, the configuration is such that the projections 59
There is also an advantage that it can be provided at a very low cost because it can be formed with a simple configuration of providing Further, the protrusion 59
Can be formed relatively long in the longitudinal direction of the guide rail 50, so that, for example, the elasticity of the weather strip is weakened over time and the upper limit position of the window glass 25 can be shifted to the upper position (accuracy). There is also an effect that it is possible to make a configuration that can make it sweeter.
