BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window molding for sealing a gap between a peripheral edge of a window glass fixed to a vehicle and a vehicle body panel, and a method for manufacturing the same.

0002

2. Description of the Related Art Generally, a window molding is attached to the peripheral edge of a window glass attached to a window opening of a vehicle body panel. Specifically, a continuous long gap is formed between the peripheral edge of the window glass and the opening edge of the window opening in the vehicle body panel, and within this gap,
A window molding made of a long extruded member is inserted and sealed. This window molding is inserted into the above-mentioned gap and fitted into a predetermined car-inside locking portion, so that the gap is covered with a decorative portion from the car-side outside.

In such automobile window moldings, it has been proposed to form grooves to dam and drain rainwater on the window glass, as described in, for example, Japanese Utility Model Publication No. 57-54416. . In this case, a portion of the molding in which a groove is formed and a portion in which a groove is not formed are molded separately, and both are placed in a predetermined mold to be integrated. However, with such a connection, a line is formed due to molding at the connection part between the two,
There are problems with decoration. On the other hand, Japanese Patent Publication No. 62-2894
No. 27, Japanese Utility Model Application Publication No. 64-28374, etc., disclose moldings in which the size of the groove that dams up rainwater is varied in the longitudinal direction of the molding. However, in these methods, when changing the size of the groove, a pair of members defining the groove are formed as separate members. Therefore, processes such as connection are required, and this also has problems in terms of molding.

In order to solve this problem, various proposals have been made in Japanese Patent Laid-Open Nos. 62-283017 and 1-269613. First, in the molding described in Japanese Patent Application Laid-Open No. 62-283017,
A decorative part of the molding material, which is continuously extruded and has a constant cross-sectional shape, is lifted and deformed through an injection molded part, and the space between the lifted part of the decorative part and the abutting piece to the window glass is A rainwater catchment groove is formed in the area. Moreover, in the one described in JP-A-1-269613,
The decorative portion extruded to have a constant cross-sectional shape is cut so as to change the formation position of the support piece defining the glass fitting groove.

[0005]

[Problems to be Solved by the Invention] However, the above-mentioned Japanese Patent Application Laid-Open No. 62-283017 and Japanese Patent Application Laid-Open No. 1-26961
In the conventional molding described in Publication No. 3, in the upper part where no groove is provided, the glass contact piece must be completely housed inside the decorative part, and the decorative part must be enlarged accordingly. I don't get it. Therefore, there is a possibility that the decorative portion becomes an obstacle to ensuring a driver's field of view, and the decorative portion may become bulged, going against the request for a so-called flush surface.

Therefore, the present invention provides a vehicle window molding that can be extruded to continuously change the rainwater drain groove that has a sufficient damming function while having a small decorative part, and its manufacture. The purpose is to provide a method.

[0007]

[Means for Solving the Problems] In order to achieve the above object, a vehicle window molding according to the present invention is installed along the edges of at least both sides of a window glass fixed to a window frame opening of a vehicle body panel. In the vehicle window molding, the vehicle window molding comprises a decorative part that covers the gap formed between the edge of the window glass and the inner peripheral edge of the window frame opening of the vehicle body panel from the outside of the vehicle. , a glass pressing piece that is arranged at a predetermined distance in the direction of the interior of the vehicle from the decorative portion in both side portions and is pressed against the outside surface of the window glass, and a window glass between the glass pressing piece and the decorative portion. Both side parts are provided with rainwater receiving grooves defined to dam up rainwater above the molding, and the distance between the decorative part and the glass pressing piece in the vehicle exterior and exterior directions is continuously changed in the longitudinal direction of the molding. As a result, the groove width of the rainwater receiving groove is continuously changed in the longitudinal direction of the molding, and the decorative part and the glass pressing piece are brought close to each other and combined at a predetermined position above the side part, so that the decorative part It has a structure in which the rainwater receiving groove disappears at the location where the glass pressing piece and the glass pressing piece come together.

[0008] Furthermore, the method for manufacturing a vehicle window molding according to the present invention includes extruding the molding attached along the edges of at least both side portions of the window glass through a molding port provided in a die of an extrusion molding device. The method includes extruding from the extrusion port of the die a decorative portion that covers the gap between the window glass and the vehicle body panel from the outside of the vehicle, and a glass pressing piece that presses against the exterior surface of the window glass. In the method for manufacturing a vehicle window molding, the molding on both side parts is extruded while changing the extrusion molding ports corresponding to the decorative part and the glass pressing piece of the die to different positional relationships. At a timing corresponding to a predetermined part above the part,
After the extrusion molding ports corresponding to the decorative portion and the glass pressing piece of the die are brought close to each other, extrusion is performed by overlapping the extrusion molding ports so as to form a single opening.

[0009]

[Function] Each means having such a configuration has a suitable rainwater drainage groove, the size of the rainwater receiving groove can be changed as necessary, and the rainwater receiving groove can appear and disappear freely, Moreover, window moldings with good decorative properties can be molded in a series by only extrusion without additional processes such as cutting.

First, as shown in FIG. 1, a window molding 2 made of an elongated extruded seal member is attached to the peripheral edge of a window glass 11 on the front side of an automobile. This window molding 2 includes an upper molding 2A installed in the gap between the upper edge of the window glass 11 and the roof panel 12, and an upper molding 2A installed in the gap between both side edges of the window glass 11 and the pillar panel 13. It has a side molding 2C that is curved, and a corner molding 2B that connects the upper molding 2A and the side molding 2C and is installed in a curved shape. It is continuously extruded as one piece.

The window molding 2 in the first embodiment shown in FIGS. 2 to 7 is made by integrally extruding an elastic material such as rubber or synthetic resin into a long strip using a molding device to be described later. , window glass 11
It has a leg part 22 inserted in a gap between the peripheral edge of the roof panel 12 and the pillar panel 13, and also between the window glass 11 and the outer surface of the roof panel 12 and the surface of the pillar panel 13. The vehicle is provided with a decorative portion 21 that covers the vehicle from the outside (the upper side of FIGS. 3 to 7). The decorative portion 21 and the leg portions 22 form a substantially T-shaped cross section perpendicular to the longitudinal direction.

[0012] The height of the leg portion 22 in the vehicle interior and exterior directions (in the vertical direction in FIGS. 3 to 7) is set short at the upper molding 2A, and set slightly longer at the side molding 2C. This corresponds to the fact that the step formed between the outer surface of the window glass 11 and the outer surface of the roof panel 12 is larger in the side portion than in the upper portion, as will be described later. The height of the leg portion 22 is also changed according to the change in the step, and is gradually raised from the corner portion (see FIG. 4) and the upper side portion (see FIG. 2 near the center (see Figures 6 and 7)
The stage height is set. Furthermore, in the lower region of the side part, the maximum height is maintained constant.

A thin metal foil core bar 23 serving as a core material is embedded in the leg portion 22 near the connection portion with the decorative portion 21. Furthermore, an engagement fixing piece 24 for supporting the lower part of the window glass 11 and an engaging fixing piece 24 for supporting the lower part of the window glass 11 are provided on the inner circumferential side and the outer circumferential side of the vehicle inner edge (lower edge in FIGS. 3 to 7) of the leg portion 22, respectively, and on the wall surface side of the vehicle body panel. Elastic lip piece 2 that protrudes toward the
5 is provided over the entire length.

On the other hand, the decorative portion 21 extends from the outer side end of the leg portion 22 (the upper end of FIGS. 3 to 7) to the window glass 11.
It has a glass side decorative part 21a and a panel side decorative part 21b extending to the side and the vehicle body panels 12 and 13, respectively. The glass-side decoration part 21a is made of a lip-shaped member that covers the outside surface of the window glass 11, and the panel-side decoration part 21b is made of a lip-like member that comes into contact with the outside surface of the vehicle body panel 12. From the upper molding 2A to the corner molding 2B, the lower side surface of the glass side decorative portion 21a as shown in the drawing and the upper side surface of the engaging fixing piece 24 as shown in the drawing are parallel to each other.
Between these two members 21a and 24, the window glass 1
A window glass fitting groove having a U-shaped cross section is defined for receiving the window glass.

On the other hand, from the upper end 2D near the corner of the side molding 2C to the lower side end, a glass pressing piece 21c is provided between the glass side decorative part 21a and the engagement fixing piece 24. This glass pressing piece 21c
protrudes from the leg portion 22 with a constant extension length, and is pressed against the vehicle outer surface of the window glass 11 with a constant width. The upper side surface of the engagement fixing piece 24 and the lower side surface of the glass pressing piece 21c are parallel to each other, and a window glass fitting groove having a U-shaped cross section is defined between them. The width is set to the thickness dimension of the window glass 11. This side window glass fitting groove and the above-mentioned upper side window glass fitting groove have the same groove shape,
It is formed continuously along the peripheral edge of the window glass 11.

The panel side decorative portion 21b and the glass side decorative portion 21a are set to have a uniform thickness and shape over the entire length of the molding, but the side molding 2
Glass side decoration part 21a and glass pressing piece 21c in C
The positional relationship with the above-mentioned window glass 1 will be described later.
1 and the surface of the roof panel 12.

That is, first, as shown in FIG. 7, from the lower part of the side molding 2C (the right part in FIG. 3) where the step is made to the maximum degree, to the central region, the maximum step is provided there. Corresponding to the difference in level, the glass side decoration part 21a and the glass pressing piece 21c are kept at the maximum distance in the vehicle exterior and exterior directions (in the vertical direction in the figure), and the maximum size A rainwater receiving groove 28 is defined. This rainwater receiving groove 28
dams up rainwater on the window glass 11, and is opened toward the inner circumference. In addition, in the central region slightly above this, as shown in FIG. 6, the height difference between the glass-side decorative portion 21a and the glass pressing piece 21c is adjusted to correspond to the height difference slightly reduced from the maximum height difference. The spacing in the medial and medial directions has been slightly reduced. The rainwater receiving groove 28 defined between these two 21a and 21c is also slightly narrower than the maximum groove depth and groove width described above.

Further, in the upper part of the molding 2C, as shown in FIG. 5, the step is continuously reduced, and the glass side decorative part 21a and the glass pressing piece 21c are correspondingly reduced. are gradually being brought closer together. The depth and width of the rainwater receiving groove 28 defined in the spaced apart portion of both 21a and 21c are also gradually reduced in the upper part of the side. Furthermore, from the upper end near the corner to the corner of the side molding 2C, as shown in FIG. The rainwater catchment groove 28 has disappeared. Furthermore, in the upper molding 2A where the step is almost eliminated, the glass pressing piece 21c is not molded as shown in FIG.
The glass-side decorative portion 21a itself having a uniform thickness is pressed onto the window glass 11.

As described above, the rainwater receiving groove 28 is recessed between the glass side decorative portion 21a and the glass pressing piece 21c in the side molding 2C so as to open inward. This rainwater receiving groove 28 has a substantially triangular cross section, and is provided from the corner end 2D of the side molding 2C to the lower side of the side molding 2C. The depth and width of the rainwater receiving groove 28 are changed in accordance with the distance between the glass side decorative portion 21a and the glass pressing piece 21c, as described above. Further, by changing the groove depth and groove width of the rainwater receiving groove 28 in this way, the respective wall thicknesses of the glass side decorative portion 21a and the glass pressing piece 21c are made uniform over the entire length.

A structure for mounting the window glass 11 on the vehicle body side using such a window molding 2 will now be described. The inner peripheral edges of the glass attachment openings provided in the roof panel 12 and the pillar panel 13 are bent in a step-like manner toward the indoor side so as to receive the window glass 11. Flange portions 12b and 13b are provided. Although the rising height of the bending wall 12a in the upper part is uniform,
The rising height of the bent wall 13a at the side portion is gradually increased from the middle of the corner portion.

First, the window molding 2 is attached to the peripheral edge of the window glass 11. At this time, from the upper edge to the corner edge of the window glass 11, the U-shaped groove between the engagement fixing piece 24 of the upper molding 2A and the glass side decoration part 21a is fitted, and the window glass 11 is A U-shaped groove between the engagement fixing piece 24 of the side molding 2C and the glass pressing piece 21c is fitted into the side peripheral edge. Note that the corner molding 2B will be curved to a predetermined curvature as the window molding is attached, but the glass side decorative portion 21a and the glass pressing piece 21c are integrated as described above, so that the wall thickness can be increased. Because of this, problems such as wrinkles due to differences in bending circumferences do not occur.

On the other hand, a band-shaped dam rubber 14 is fixed onto the flange portions 12b, 13b on the side of the vehicle body panels 12, 13, and an adhesive 15 is filled into the outer peripheral surface of the dam rubber 14 by extrusion. Then, the interior side surface of the window glass 11 to which the window molding 2 is attached is brought into contact with and pressed against the dam rubber 14. As a result, the engagement fixing piece 24 of the window molding 2 is fixed with the adhesive 15, and the elastic lip piece 25 is brought into elastic contact with each bending wall 12a, 13a in a bent shape. The elastic repulsive force caused by the bending of the elastic lip piece 25 acts as a fixing force for the window molding 2.

In this way, the window glass 11 is
It is fixed on the flange portions 12b, 13b on the vehicle body panels 12, 13 side at a substantially uniform height all around. A step is formed between the outside surface of the window glass 11 and the surfaces of the vehicle body panels 12 and 13, corresponding to the rising height of the bent walls 12a and 13a. , the distance between the glass side decorative portion 21a and the glass pressing piece 21c is set.

First, the largest step is provided from the lower side area to the center area (see FIG. 7), and the glass side decorative portion 21a and the glass pressing piece 21 correspond to this step.
c, that is, the size of the rainwater receiving groove 28 is also maximized. In addition, in a region slightly above this (see FIG. 6), a level difference that is slightly reduced from the maximum level difference is provided, and corresponding to this level difference, the glass side decorative portion 21a
The distance between the glass pressing piece 21c and the glass pressing piece 21c in the vehicle interior and exterior directions is slightly reduced, and the size of the rainwater receiving groove 28 is also slightly reduced accordingly. In addition, from the upper part of the side molding 2C to the corner part (see Figs. 5 and 4),
The step is continuously reduced, and correspondingly, the glass side decorative portion 21a and the glass pressing piece 21c are gradually brought closer to each other, and the groove depth and groove width of the rainwater receiving groove 28 are also continuously reduced. has been done. At this time, as described above, at the upper end of the side molding 2C near the corner, the glass side decorative part 21a and the glass pressing piece 21c
The rainwater receiving groove 28 disappears at this integrated part. Further, from the middle part of the corner part toward the upper part (see FIG. 4), the level difference is set to be extremely small, and correspondingly, the height difference between the integrated glass side decorative part 21a and the glass pressing piece 21c is set to be extremely small. , the thick part of the glass pressing piece 21c is gradually reduced and disappears at the end near the corner of the upper part. Therefore, in the upper part where there are almost no steps (see FIG. 3), the entire length is made up only of the thickness of the glass side decorative part 21a.

In such a structure for mounting the window glass 11 on the vehicle body side, rainwater that has formed on the window glass 11 is led to the inner circumferential wall of the window molding 2 and discharged to a predetermined location. That is, from the upper part to the corner part, the rainwater that is guided to the inner circumferential wall surface of the glass-side decorative part 21a and collected on the side part is defined between the glass-side decorative part 21a and the glass pressing piece 21c. The rainwater is guided through the rainwater receiving groove 28. At this time, the groove depth of the rainwater receiving groove 28 is varied so as to give good fluidity to the rainwater in the rainwater receiving groove 28, so that suitable drainage is performed.

The window molding 2 may be inserted into the window frame side while being attached to the window glass 11, or the window molding 2 may be inserted into the window frame side in advance, and then the window molding 2 may be inserted into the window frame side after being attached to the window glass 11. The window molding 2 may be inserted into the gap between the peripheral edge and the vehicle body panels 12, 13.

Next, an apparatus for forming the above-mentioned window molding 2 will be explained. As shown in FIGS. 8, 9, and 10, the molding device 3 includes three dies for forming openings for extruding synthetic resin. These dies include a first die 31 and a second die 31 that are arranged in parallel in the molding extrusion direction (perpendicular to the paper surface).
die 32 and a third die 33. The first die 31 is installed in a fixed state and includes an extrusion forming port 34 for forming the decorative portion 21 of the window molding 2. Furthermore, the extrusion openings corresponding to the leg portions 22, support portions 24, and elastic lips 25 of the window molding 2 are formed into large rectangular openings that include these portions.

[0028] The extrusion forming port 34 is formed in the panel side decorative part 2.
The opening 341 corresponding to 1b and the glass side decorative part 21a
It has an opening 343 corresponding to the glass pressing piece 21c, and an opening 345 corresponding to the glass pressing piece 21c. Among these, the opening 341 and the opening 343 have a common upper edge having an arcuate curved outer shape corresponding to the upper edge of the decorative part of the window molding 2, and the lower edge of the opening 341 has a shielding part. 3
42, it has a shape that matches the panel side decorative portion 21b. Further, the openings 343 and 345 have a shape in which the glass side decorative portion 21a and the glass pressing piece 21c are continuous in a thick wall shape without forming the rainwater receiving groove 28.

On the other hand, the second die 32 and the third die 33 are each formed from a plate-like member, and a pair of guides 32a, 32a and 3 are provided on the front surface of the first die 31.
3a and 33a so as to be able to move in parallel. The extrusion forming port 35 provided in the second die 32 has a shape corresponding to the leg part 22, the support part 24, and the elastic lip 25 of the window molding 2, and the open part provided at the upper end in the figure is They are overlapped so as to communicate with the extrusion forming port 34 side of the first die 31. A connecting rod 32d is provided at the lower edge of the second die 32 in the drawing, and this connecting rod 32d is connected to a drive motor 32c via a converter 32b that converts rotational motion into linear motion.
is connected to. The second die 32 is reciprocated between the upper molding forming position shown in FIG. 8 and the side molding forming position shown in FIGS. 9 and 10 by the driving force from the driving motor 32c. It has become so.

Further, the third die 33 is similar to the second die 3 described above.
A connecting rod 33d provided at the left edge of the third die 33 in the figure converts rotational motion into linear motion.
It is connected to a drive motor 33c via 3b. A substantially triangular shielding protrusion 331 corresponding to the rainwater receiving groove 28 of the window molding 2 described above is formed at the tip of the third die 33 on the right side in the drawing. The shielding protrusion 331 of the third die 33 is provided so as to be able to enter into the connection area between the openings 343 and 345 of the first die 31, as shown in FIGS. 8 to 10. In addition, the die 2 is moved back and forth in conjunction with the reciprocation of the die 32 of the die 2.

A method of forming the window molding 2 using the molding apparatus 3 will be described. When molding window molding 2,
Upper molding 2A, corner molding 2B, and side molding 2C are extruded in series, but the order of molding is that one side molding 2
C, one corner molding 2B, upper molding 2A, then the other corner molding 2B, and the other side molding 2C.

First, when extruding the side molding 2C, the first die 31 and the second die 3
A second die 33 and a third die 33 are positioned as shown in FIG. be done. At this time, the opening 343 and the opening 345 of the first die 31
The extrusion molding starts from the lower end portion (the right end portion in FIG. 3) of the side molding 2C. That is, the glass side decorative part 21a and the glass pressing piece 2
1c and the cross-sectional area of the rainwater receiving groove 28 are maximized, and extrusion molding is started with the cross-sectional shape shown in FIG. The maximum cross-sectional area of the rainwater receiving groove 28 is extruded to have a constant length.

After the lower end portion of the side molding 2C is extruded over a certain length while maintaining a constant cross-sectional shape, the second die 32 begins to be moved upward in the Y direction in FIG. As a result, the opening 343 of the first die 31 and the opening 3
45 are gradually brought closer to each other, and thus extrusion molding is performed while the glass side decorative portion 21a and the glass pressing piece 21c are brought closer to each other. At this time, each part other than the glass-side decorative part 21a and the glass pressing piece 21c is maintained in the same cross-sectional shape.

At the same time, the third die 33 is retracted in the V direction in proportion to the amount of proximity between the glass side decorative part 21a and the glass pressing piece 21c, thereby causing the glass side decorative part 21a and the glass pressing piece 21c to move backward. The cross-sectional area of the rainwater receiving groove 28 formed between the piece 21c is gradually reduced. The third die 33 is moved in synchronization with the moving speed of the second die 32, thereby maintaining the thickness of the glass-side decorative portion 21a and the glass pressing piece 21c uniform.

When the state shown in FIG. 9 is reached, the third die 33 is temporarily stopped, and the central portion of the side molding 2C is extruded over a certain length in the cross-sectional shape shown in FIG. . Next, when approaching the upper end position of the side part, that is, the molding position near the corner of the side molding 2C, the second die 32 is pushed up again in the Y direction, and the third die 33
is being pulled in the V direction. As a result, the distance between the opening 343 and the opening 345 of the first die 31 is reduced, the distance between the glass-side decorative portion 21a and the glass pressing piece 21c is also reduced, and the groove of the rainwater receiving groove 28 is reduced. The cross-sectional area is reduced in proportion to the amount of proximity movement between the glass-side decorative portion 21a and the glass pressing piece 21c. At this time, other parts are maintained in the same cross-sectional shape. Also at this time, since the third die 33 is moved in synchronization with the moving speed of the second die 32, the glass side decorative part 2
The thicknesses of 1a and the glass pressing piece 21c are maintained uniform. Further, the second die 32 is pushed up in the Y direction, and the third die 3 is moved from the openings 343 and 345 of the first die 31
3 are separated, the glass side decoration part 21a and the glass pressing piece 21c are integrated, and the rainwater receiving groove 28
is deleted.

Next, extrusion molding of the corner molding 2B is performed, and the second die 32 and the third die 33 are
reaches the position shown in FIG. In other words, when the upper edge of the second die 32 is overlapped with the edge of the shielding part 342 of the first die 31 so that they are on the same line, the entire extrusion forming opening is formed in the cross-sectional shape of the upper molding 2A. After that, the upper molding 2A is extruded to have a constant cross-sectional shape.

Once the upper molding 2A has been extruded over a certain length, the above-mentioned procedure is reversed and
The corner molding 2B and side molding 2C on the other side are extruded to obtain a series of window moldings 2.

Next, in the window molding 4 according to the second embodiment of the present invention shown in FIGS. 11, 12 and 13, in place of the leg portion 22 of the window molding 2 according to the first embodiment described above, A molding frame 42 formed by bending a metal plate into a predetermined shape is employed. This molding frame 42 is arranged along the peripheral edge of the window glass 11, and is fixed to the vehicle body panels 12 and 13 by various fixing means such as clips and bolts (not shown). The mall frame 4
2 is formed to have a constant cross-sectional shape over its entire length, but in response to the change in level between the window glass 11 and the vehicle body panels 12 and 13, the side portions are slightly spaced apart from the window glass 11 toward the outside of the vehicle. It is located.

A decorative portion 41 is integrally provided on the molding frame 42 by extrusion molding. This decorative portion 41 is provided on the outer peripheral side of the molding frame 42 and extends toward the vehicle body panels 12 and 13.
b, and a glass side decorative portion 41a provided on the inner peripheral side of the molding frame 42 and extending toward the window glass 11 side. The glass-side decorative portion 41a of the upper molding 4A is in close contact with the outer surface of the window glass 11, but the glass-side decorative portion 41a of the side molding 4C has the molding frame 42 spaced apart from the window glass 11 as described above. It is arranged so as to be spaced apart from the window glass 11, corresponding to the height difference between the window glass 11 and the vehicle body panels 12 and 13.

Further, in a portion where the glass side decorative portion 41a is separated from the window glass 11, a glass pressing piece 4 is provided at a predetermined distance from the glass side decorative portion 41a.
1c is provided. This glass pressing piece 41c is provided only on the side molding 4C, and is pressed against both side edges of the window glass 11 from the outside of the vehicle. In addition, in upper molding 4A,
The glass pressing piece 41c is not provided, and the glass side decorative portion 41a itself is pressed against the upper edge of the outer surface of the window glass 11.

Similar to the first embodiment, the distance between the glass pressing piece 41c and the glass side decorative portion 41a in the vehicle exterior and exterior directions (vertical direction in the drawing) is between the vehicle exterior surface of the window glass 11 and the vehicle body panels 12, 13. It has been changed to correspond to the difference in level between the two. That is, first, as shown in FIG. 13, on the lower side of the side molding 4C, the glass side decoration part 41a and the glass pressing piece 41c are separated by the maximum distance in the vehicle exterior and exterior directions (vertical direction in the figure), These glass side decorative parts 41a and glass pressing pieces 4
The depth and width of the rainwater receiving groove 48 defined between the rainwater receiving groove 1c and the rainwater receiving groove 48 having a substantially triangular cross section are also maximized. Also, as shown in Figure 12, side molding 4C

The groove depth and groove width of 48 are also gradually reduced. And side molding 4C
At the upper end portion near the corner, the glass side decorative portion 41a and the glass pressing piece 41c are integrated, and the rainwater receiving groove 28 has disappeared at this portion.

As described above, the depth and width of the rainwater receiving groove 48 are changed in proportion to the distance between the glass side decorative portion 41a and the glass pressing piece 41c, and the rainwater receiving groove 48 is The wall thicknesses of the glass-side decorative portion 41a and the glass pressing piece 41c are maintained constant. Even in the window molding 4 according to the second embodiment, the same functions and effects as those of the first embodiment described above can be obtained.

Next, the window molding 9 according to the third embodiment shown in FIGS. 14 to 17 includes a side molding 9C and a side molding 9C.
It has a series of upper moldings 9A extending from the upper end of C toward the roof panel side, and uses a molding frame 92 fixed to the vehicle body panels 12 and 13 side. This molding frame 92 has a decorative portion 9.
A glass side decorative portion 91a constituting the window glass 11 and a glass pressing piece 91c that is pressed against the vehicle outer surface of the window glass 11 are integrally provided by extrusion molding. The glass pressing piece 91c is provided only on the side molding 9C and not on the upper molding 9A. In the upper molding 9A, the glass side decorative portion 91a is pressed against the vehicle outer surface of the roof panel 12.

The molding frame 92 is formed to have a constant cross-sectional shape over its entire length, but in the side portion, the window glass 11 and the vehicle body panels 12, 13
The window glass 11 is arranged at a slight distance from the window glass 11 toward the outside of the vehicle in response to a change in level. Therefore, the glass-side decorative portion 91a in the side portion is arranged so that the molding frame 92 is spaced apart from the window glass 11, that is, in response to the change in level between the window glass 11 and the vehicle body panels 12 and 13. It is arranged apart from the glass 11.

The distance between the glass pressing piece 91c and the glass side decorative portion 91a in the vehicle exterior and exterior directions (in the vertical direction in the drawing) is the same as that between the vehicle exterior surface of the window glass 11 and the vehicle body panels 12, 13, as in each of the embodiments described above. It has been changed to correspond to the difference in level between the two. First, as shown in FIG. 17, on the lower side of the side molding 9C, the glass side decorative portion 91a and the glass pressing piece 91c are separated by the maximum distance in the vehicle exterior and exterior directions (vertical direction in the figure). The depth and width of the rainwater receiving groove 98 defined between the glass side decoration part 91a and the glass pressing piece 91c and having a substantially triangular cross section are also maximized. In addition, in the area slightly above this shown in FIG. 16, the glass side decorative portion 91a and the glass pressing piece 9 are
1c are gradually brought closer to each other, and both of them 91a, 9
The depth and width of the rainwater receiving groove 98 defined in the spaced apart portion 1c are also gradually reduced. At the upper end portion of the side molding 9C near the roof, the glass side decorative portion 91a and the glass pressing piece 91c are integrated as shown in FIG. 15, and therefore the rainwater receiving groove 28 has disappeared at this portion.

As described above, the depth and width of the rainwater receiving groove 98 are changed in proportion to the distance between the glass side decorative portion 91a and the glass pressing piece 91c, and the rainwater receiving groove 98 is The wall thicknesses of the glass-side decorative portion 91a and the glass pressing piece 91c are maintained constant. Even in the window molding 9 according to the third embodiment, the same functions and effects as in the first embodiment described above can be obtained.

Furthermore, the window molding according to each of the embodiments described above can be applied not only to a front window glass but also to other window glasses such as a rear window glass.

As described above, the present invention adjusts the distance between the window molding's glass abutting piece and the decorative part, which are attached from the side part of the window glass to the other parts, in the vehicle interior and exterior directions by adjusting the distance in the longitudinal direction of the molding. The groove depth and groove width of the rainwater receiving groove are made smaller in the upper part of the side part by making the grooves continuously different from each other.
Since the decorative part and the glass abutting piece are integrally molded at the upper end of the side part, the entire length of the molding can be extruded in a series, and the window is equipped with a rainwater drainage groove with sufficient damming function. Molding can be performed easily and continuously.
