BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a door structure of a vehicle which can 
form a flush surface. 
2. Description of the Prior Art 
In the field of vehicles, particularly automobiles, it has been recently 
attempted to remove step portions from the outer surface of a car body as 
much as possible to form a so-called flush surface so as to enhance the 
aerodynamic characteristics. As door structure to realize the flush 
surface, an inner sash is known in which each vertically movable door 
window is arranged to the outside of a door sash extending upward from a 
main body of the door, as disclosed in Japanese Laid-Open Utility Model 
No. 114012 (1985). 
In the above-mentioned door structure, since the door sash is positioned in 
a compartment, a guide mechanism for guiding the door glass is provided so 
as not to impair the external appearance and to make the vertical movement 
of the door window smooth. For the guide mechanism of the door window, a 
flange portion of the door sash is utilized, and the mechanism is composed 
of the flange portion and a guide shoe which is arranged to slide along 
the flange portion on the side of the inner face of the door window. 
Between the door window and the door sash, a seal is provided by a weather 
strip independently disposed at the door sash. 
However, in the above-mentioned conventional structure, since the flange 
portion is necessary for the door sash, there is required a trim panel for 
covering the flange portion to exhibit an aesthetic appearance. Moreover, 
it is also required to fix the guide shoe to the inner face of the door 
window in the structure. The guide shoe must be attached to the door 
window with sufficient attachment strength. Thus a stopper is used which 
engages the guide shoe through the door window from the outer face 
thereof. Accordingly, since the stopper is exposed at the outer face of 
the door window, the external appearance of the door is impaired. 
Furthermore, the weather strip which is provided along the door sash in 
order to form a seal between the door window and the door sash is easily 
deformed because it comprises a flexible material. The deformation of the 
weather strip causes the external appearance to be impaired. Moreover, 
there occurs a relatively large space between the guide shoe and the door 
sash which causes problems in that wind-generated noise tends to be heard 
in the compartment during traveling of the vehicle to impair the quietness 
in the compartment, etc. Additionally, the external appearance around a 
corner portion defined by the door sash and the main body of the door is 
inferior. 
SUMMARY OF THE INVENTION 
In order to solve these problems, the present invention is characterized by 
comprising a door body of a car capable of opening and closing, and 
defining the inside and outside of a passenger compartment; a door sash 
provided at the upper portion of the door body to form a window space; a 
door window provided movably in the vertical direction on the door sash 
outwardly of the compartment for opening and closing the window space; a 
corner portion defined by the door sash and the door body at the front end 
portion of the door sash; a corner bracket provided at the corner portion 
to close the corner portion; a glass guide provided at the front end 
portion of the door sash and extending vertically along the rear end 
portion of the corner bracket for guiding the front edge portion of the 
door window vertically; a weather strip provided at the door sash to seal 
a space between the door sash and the door window, having a glass guide 
portion which extends to an external peripheral edge portion of the door 
window from an internal peripheral edge portion thereof, and extending to 
the front end portion of the corner bracket along the door sash which 
terminates at the front end portion of the corner bracket; and core 
material embedded, adjacent the edge of the door window, in the glass 
guide portion of the weather strip so as to reinforce the portion. 
In the above-mentioned structure, the stiffness of the weather strip is 
enhanced by embedding the core material in the glass guide portion 
thereof. Thus the weather strip has a guiding function and a sealing 
function with respect to the door window. Accordingly, the rear edge 
portion and the front edge portion of the door window are respectively 
guided by the glass guide portion of the weather strip and the glass guide 
provided at the rear edge portion of the corner bracket, so that the door 
window can be moved smoothly in the vertical direction. Thus, it is 
unnecessary to independently provide another guide mechanism for the door 
window, and the problem of the external appearance being impaired by the 
guide mechanism can be solved. Moreover, since the core material is 
embedded in the glass guide portion of the weather strip, deformation of 
the weather strip hardly occurs thereby also contributing to the improved 
external appearance. Furthermore, since the guide of the door window and 
the seal between the door window and the door sash are effected by the 
weather strip without providing another guide mechanism, the space formed 
between the door glass and the door sash when the door window is closed is 
slight, so that the wind-generated noise during traveling of the vehicle 
is hardly heard in the compartment. 
Since the front end portion of the door sash extends forward along the 
front edge portion of the corner bracket, and the weather strip extends 
forward along the door sash, it becomes possible to arrange the weather 
strip continuously along, for example, a drip molding without any 
deformation therein. And in particular, the external appearance of the 
corner portion at which is provided the corner bracket can be improved. 
The weather strip may comprise an elastic member, and the core material may 
comprise a metal. 
Moreover, the core material may extend as embedded in the glass guide 
portion to a location adjacent the outer peripheral portion of the door 
window adjacent the edge thereof from an internal peripheral portion of 
the door window adjacent the edge thereof. 
The door sash may be composed of an extending portion connected to the rear 
end portion of the door body and extending vertically upward therefrom, 
and an upper frame portion which extends forward and substantially 
horizontally from the upper end portion of the extending portion, and 
further extends forward and downward in an inclined attitude, and the 
front end portion of which is connected to the front end portion of the 
door body to form the corner portion between the front end portion of the 
upper frame portion and the door body. Moreover, the weather strip may be 
disposed to extend from the extending portion of the door sash along the 
upper frame portion to the front end portion of the upper frame portion of 
the door sash. 
Furthermore, the car body may be formed with a panel body, and the weather 
strip may establish a seal between the door sash and the panel body 
adjacent to the door sash when the door body is closed. 
The weather strip may include an attachment portion to be attached to the 
door sash, a glass run channel portion for guiding the vertical movement 
of the rear edge portion of the door window, and a lip portion defining a 
sealing face. The glass run channel portion of the weather strip may form 
an outer surface guide portion for guiding the door window by extending 
from the internal surface of the door window to the external surface 
thereof so that the peripheral portion of the door window is surrounded 
and held by the glass run channel portion. Further, the core material may 
be embedded in the weather strip so as to extend from the outer surface 
guide portion of the glass run channel portion to the attachment portion. 
Further, the glass run channel portion of the weather strip may have a 
water cut-off seal portion in slidable contact with the glass surface of 
the door window. 
The panel body may comprise a front pillar, a center pillar and a roof rail 
which define a door space which is selectively opened and closed by the 
door body. To the front pillar and the roof rail is attached a drip 
molding, and to the center pillar is attached a trim panel for covering 
the exterior of the center pillar. Further, the lip portion of the weather 
strip is disposed in substantially the same plane as the outer surface 
guide portion of the glass run channel portion, and the lip portion is in 
contact with the door sash, trim panel and drip-molding so as to cover a 
space between such when the door body is closed. Moreover, a seaming welt 
may be attached to the front pillar, center pillar and roof rail, 
respectively. At the seaming welt is another weather strip in contact with 
the door sash to as to establish a seal. Additionally, the door sash may 
have another weather strip which establishes a seal between the door sash 
and the front pillar, center pillar and roof rail when the door body is 
closed. 
The glass guide may be provided at the corner bracket and may comprise an 
elastic member. 
Further, a core material may be embedded in the glass guide. The core 
material may be a core metal. Moreover, the glass guide may comprise a 
weather strip having an attachment portion, a glass run channel portion 
for guiding the front edge portion of the door window and a lip portion. 
And, the glass run channel portion has an opening which opens toward the 
window space and is arranged at the external surface of the corner 
bracket. 
A covering member for covering the external surface of the corner bracket 
may be provided thereon. The corner bracket may be a closed 
cross-sectional structure. Moreover, the corner bracket may comprise an 
outer panel and an inner panel with the front edge portions of the panels 
being connected to each other and jointed to the front end portion of the 
door sash, and an auxiliary frame connecting the rear edge portions of 
these panels. The outer panel, inner panel and auxiliary frame 
collectively form a closed cross-sectional structure and the covering 
member extends from a front edge portion thereof at the weather strip to a 
rear edge portion thereof at the glass guide so as to close the space 
between the weather strip and the glass guide. And, a trim panel is 
attached to the internal surface of the inner panel. 
The corner bracket may comprise a main panel and an auxiliary frame, and 
the front edge portion of the main panel is attached to the door sash, 
while the rear edge portion thereof forms a channel portion together with 
the auxiliary frame. To the channel portion is attached the glass guide, 
and a covering member is attached to the external surface of the main 
panel. 
The corner bracket may also comprise a main panel, an auxiliary frame and a 
support frame. The front edge portion of the main panel is attached to the 
door sash, and to the rear edge portion of the main panel is attached the 
auxiliary frame. And the support frame has a channel portion which faces 
the glass run channel portion of the weather strip, adjacent the glass 
guide. The channel portion is covered by a covering member, and between 
the channel portion and the glass run channel portion is provided a glass 
plate. A trim panel is attached to the internal surface of the main panel. 
Further, the corner bracket may comprise an outer panel, an inner panel and 
an auxiliary frame. The front edge portion of the outer panel is connected 
to the inner panel, and the front edge portion of the inner panel is 
attached to the door sash, further, the rear edge portions of these panels 
are connected to each other through the auxiliary frame to form a closed 
cross-sectional structure. At the external surface of the outer panel is 
provided a covering member, and the front edge portion of the covering 
member is inserted into the glass run channel portion of the weather 
strip, while the rear edge portion thereof is in contact with the lip 
portion of the glass guide. A trim panel is attached to the internal 
surface of the inner panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
(Embodiment 1) 
A first embodiment of the present invention will be described below 
referring to FIGS. 1 to 6. 
An automobile as a vehicle is provided with front doors 2 and rear doors 3 
at its body 1 as shown in FIG. 1. Both the doors 2 and 3 are of a 
so-called inner-sash type where, as will be described below, door sashes 6 
are provided on the inner side of door windows 4. 
The front door 2 has a main door body 5 which is composed of a panel, as 
shown in FIG. 2(A). Above the main door body 5 is provided a door sash 6 
which forms a window space. The door sash 6 comprises an extending portion 
6a which is connected to the main door body 5 near the rear end portion of 
main door body 5 and extends upward, and an upper frame portion 6b which 
extends forward and substantially horizontally from the upper end portion 
of the extending portion 6a, and further extends forward and downward and 
is connected to the main door body 5 near the front end portion of main 
door body 5. At a front portion of the upper frame portion 6b is 
vertically arranged an auxiliary frame 27 extending from the door sash 6 
into the main door body 5 disposed therebelow. At a corner portion 8 which 
is formed by the auxiliary frame 27, a corner bracket 26 is provided. A 
first weather strip 19 extends from the extending portion 6a of the door 
sash 6 along the upper frame portion 6b to the front end portion of the 
door sash 6 as shown in FIG. 2(B). Moreover, a glass guide 7 for guiding 
the front edge portion of the door window 4 extends along the auxiliary 
frame 27. Accordingly, the door sash 6 extends along the upper edge 
portion of the corner bracket 26 substantially up to the front end portion 
of the main door body 5, and the glass guide 7 extends vertically along 
the rear edge portion of the corner bracket 26. At the corner portion 8, a 
door mirror 9 is attached as shown in FIG. 1. 
As shown in FIGS. 3 and 4, respectively, the extending portion 6a and the 
upper frame portion 6b of the door sash 6 have a facing portion 10 which 
faces the inner face 4a of the door window 4, a crossing portion 11 which 
extends toward the compartment laterally from the central portion of the 
facing portion 10, and a bending portion 12 which extends toward the 
window space substantially perpendicularly from an end portion of the 
crossing portion 11 on the side of the compartment. A part of the facing 
portion 10 on the side of the window space, the crossing portion 11 and 
the bending portion 12 form a U-shaped cross-sectional portion 13 which 
opens toward the window space. 
Formed opposite to the U-shaped cross-sectional portion 13 is a weather 
strip fitting portion 11a , and in the weather strip fitting portion 11a 
is fitted a second weather strip 14. The second weather strip 14 is 
constructed such that it may seal, when the front door 2 is closed, a 
space between the door sash 6 and a center pillar 15 comprising an outer 
panel 15a and an inner panel 15b as shown in FIG. 3, a space between the 
door sash 6 and a roof rail 16 comprising an outer panel 16a and an inner 
panel 16b as shown in FIG. 4, and a space between the door sash 6 and a 
front pillar 53 comprising an outer panel 53a and an inner panel 53b as 
shown in FIGS. 5 and 6. Around a joint portion 15c of the outer panel 15a 
and inner panel 15b in the center pillar 15, a joint portion 16c of the 
outer panel 16a and inner panel 16b in the roof rail 16, and a joint 
portion 53c of the outer panel 53a and inner panel 53b in the front pillar 
53 is respectively fitted a seaming welt 17. At the seaming welt 17, a 
third weather strip 18 is integrally provided, and the third weather strip 
18 is in contact with the bending portion 12 of the door sash 6 so as to 
aid in the prevention of the penetration of water between the door sash 6 
and the car body 1. 
Further, a fitting portion 10a is formed at the end of the facing portion 
10 of the door sash 6 on the side of the center pillar 15 or the roof rail 
16. The first weather strip 19 is fitted in the fitting portion 10a and 
the U-shaped cross-sectional portion 13 so as to be attached to the door 
sash 6. The first weather strip 19 has a holding portion 20 which is 
fitted in the U-shaped cross-sectional portion 13, a glass run channel 
portion 21 (hereinafter called GRC portion) which is a glass guide for 
guiding the door window 4 vertically and a lip portion 22. The lip portion 
22 is in contact with a pillar trim panel 24 which covers the outer 
surface of the center pillar 15, and a drip-molding 25 which is attached 
to the roof rail 16 and the front pillar 53, so that it may cover, when 
the front door 2 is closed, a space between the door sash 6 and the pillar 
trim panel 24 or the drip-molding 25. 
The holding portion 20 has a first projecting portion 20a which extends 
toward the inside of the U-shaped cross-sectional portion 13 along the 
facing portion 10 of the door sash 6, and a second projecting portion 20b 
which extends along the bending portion 12. The GRC portion 21 extends 
toward the fitting portion 10a from the holding portion 20 along the 
facing portion 10 of the door sash 6, and forms an outer face guide 
portion 21a by curving slightly toward the outer face 4b of the door 
window 4 so as to hold the peripheral part of the door window 4 
therebetween. The GRC portion 21 has a hollow and ridgy water cut-off 
portion 21b and a plurality of projecting/plate-like water cut-off 
portions 21c. With respect to the GRC portion 21 of the first weather 
strip 19 in the upper frame portion 6b of the door sash 6 as shown in FIG. 
4, a guiding function of the door window 4 is not so important, and thus 
it is possible that the length of the outer face guide portion 21a at the 
upper frame portion 6b be shorter than that at the extending portion 6a so 
that the number of the water cut-off portions 21c is reduced. However, 
since the outer face 4b of the door window 4 is under negative pressure 
during travel, it is necessary for the GRC portion 21 in the upper frame 
portion 6b to have a guiding function that can at least prevent the door 
window 4 from being pulled out by the negative pressure. The lip portion 
22 is provided at the GRC portion 21, and extends in substantially the 
same plane as the outer face guide portion 21a in the opposite direction 
to the outer face guide portion 21a. 
In the first weather strip 19 is embedded core material comprising a piece 
of sheet metal 23 extending from the outer face guide portion 21a of the 
GRC portion 21 to the first projecting portion 20a of the holding portion 
20. With this, stiffness is given to the GRC portion 21 and a part of the 
holding portion 20, so that the GRC portion 21 can be provided to function 
as a glass guide of the door window 4 and the first weather strip 19 can 
be secured with a high attachment strength to the door sash 6. 
As discussed above, at the above-mentioned corner portion 8, as shown in 
FIG. 2, the corner bracket 26 is provide. As shown in FIGS. 5 and 6, the 
corner bracket 26 comprises an outer panel 26a, inner panel 26b and 
auxiliary frame 27 which has a U-shaped cross section. The front edge 
portions of the outer panel 26a and the inner panel 26b are connected to 
each other, and further bent to connect to the U-shaped cross sectional 
portion 13 of the door sash 6, and the rear edge portions thereof are 
connected to each other through the auxiliary frame 27. The front portion 
of the outer panel 26a is bent toward the side of the inner panel 26b so 
as to guarantee a space in which the first weather strip 19 is attached to 
the door sash 6. Accordingly, the corner bracket 26 has a closed 
cross-sectional shape formed by the cross-sections of the outer panel 26a, 
inner panel 26b and auxiliary frame 27. Incidentally, the holding portion 
20 of the first weather strip 19 at the corner portion 8 has a form in 
which only the first projecting portion 20a remains and the other portions 
thereof are cut away so that the front edge portion of the corner bracket 
26 can be inserted into the weather strip fitting portion 11a of the door 
sash 6. 
Around the auxiliary frame 27 is fitted the glass guide 7 comprising a 
weather strip. The glass guide 7 has, similarly to the first weather strip 
19, a holding portion 28, a GRC portion 29 having a U-shaped cross section 
for guiding the front edge portion of the door window 4, and a lip portion 
30. The holding portion 28 has a first projecting portion 28a and a second 
projecting portion 28b. The GRC portion 29 is provided at the outer face 
of the outer panel 26a so as to open toward the window space for guiding 
the door window 4. The GRC portion 29 has an outer face guide portion 29a 
and water cut-off portions 29c. In the glass guide 7 is embedded a core of 
metal 31 extending from the outer face guide portion 29a of the GRC 
portion 29 to the first projecting portion 28a of the holding portion 28, 
and thus the glass guide 7 has stiffness sufficient to guide the door 
window 4. 
At the outer face of the outer panel 26a of the corner bracket 26, a trim 
panel 32 is provided. The trim panel 32 has an attaching convex portion 
32a which is formed near the central portion of the inner face thereof, 
and the attaching convex portion 32a is fixed at the outer panel 26a with 
a screw 33. The front edge of the trim panel 32 is located at the outer 
face of the outer face guide portion 21a of the GRC portion 21 of the 
first weather strip 19, while the rear edge portion thereof is located at 
the outer face of the outer face guide portion 29a in the GRC portion 29 
of the glass guide 7, and thus the trim panel 32 covers an opening defined 
between the first weather strip 19 and the glass guide 7. In this case, at 
the outer panel 26a of the corner bracket 26, a mirror base may be 
arranged instead of the trim panel 32. Further, at the inner face of the 
inner panel 26b is attached another trim panel 34 which covers the inner 
face. 
In the above-mentioned structure, the rear edge portion and the upper edge 
portion of the door window 4 are guided by the GRC portion 21 of the first 
weather strip 19, and the front edge portion thereof is guided by the 
glass guide 7 which is provided independently, and thus the door window 4 
can be moved smoothly in the vertical direction. Moreover, at the portion 
corresponding to the extending portion 6a and the upper frame portion 6b 
of the door sash 6, a core metal 23 is embedded in the GRC portion 21 
having a U-shaped cross section of the first weather strip 19, so that 
stiffness at that portion is enhanced to make it possible for the GRC 
portion 21 to guide the door window 4. Accordingly, it becomes unnecessary 
to independently provide another guide mechanism for the door window 4. 
Moreover, in selecting the shape of the door sash 6, it is not required to 
consider any restriction on the guide mechanism, and the disadvantage that 
the external appearance is impaired by providing the guide mechanism is 
eliminated. Further, the guide of the door window 4 and the seal between 
the door window 4 and the door sash 6 are effected by the first weather 
strip 19 and the glass guide 7 without providing another guide mechanism 
for the door window 4. Thus, a space which occurs between the door window 
4 and the door sash 6 when the door window 4 is closed is slight, and the 
wind-generated noise during traveling is hardly heard in the passenger 
compartment. Accordingly, the quietness in the compartment is improved. 
Since the core metal 23 is embedded in the GRC portion 21 of the first 
weather strip 19, deformation of the portion hardly occurs, thereby also 
improving the external appearance. Further, since the door sash 6 extends 
along the corner bracket 26 substantially up to the front end portion of 
the main door body 5, and the first weather strip 19 extends along the 
door sash 6 substantially up to the front end portion of the main body 5, 
it is possible to make the first weather strip 19 extend along the 
drip-molding 25 in a constant and continuous state without changing its 
external appearance. Accordingly, the external appearance, particularly 
that around the corner portion 8, can be improved. Moreover, since the 
corner bracket 26 has a closed cross-sectional structure, it exhibits good 
strength. 
(Embodiment 2) 
A second embodiment of the present invention will be described below 
referring to FIGS. 7 and 8. For the convenience of the description, the 
same members as shown in the drawings of Embodiment 1 are indicated by the 
same numerals or characters, and the detailed description thereof will be 
omitted. 
A door structure of a vehicle according to this embodiment has a corner 
bracket 37 comprising a main panel 35 and an auxiliary frame 36 at a 
corner portion 8 as shown in FIGS. 7 and 8. The front edge portion of the 
main panel 35 is bent and connected to a U-shaped cross-sectional portion 
13 of a door sash 6. The auxiliary frame 36 is connected to a rear portion 
of the main panel 35 and forms a U-shaped cross-sectional portion 37a 
together with the main panel 35. A glass guide 7 is fitted in the U-shaped 
cross-sectional portion 37a. At the outer face of the main panel 35 is 
provided a trim panel 38. An attachment convex portion 38a of the trim 
panel 38 is fixedly mounted with a screw 33 to a convex portion 35a of the 
main panel 35 which projects toward the outside of the car. 
In the above-mentioned structure, the corner bracket 37 is a one-plate 
structure so to be simple. Accordingly, with such a structure, a car body 
1 can be lightened and its cost can be reduced. 
Similar to Embodiment 1 , a guide mechanism becomes unnecessary, the 
external appearance can be improved because deformation of a GRC portion 
21 of a first weather strip 19 hardly occurs, the wind-generated noise 
during traveling is hardly heard in the compartment, and the external 
appearance around the corner portion 8 can be improved. 
(Embodiment 3) 
A third embodiment of the present invention will be described below 
referring to FIGS. 9 and 10. For the convenience of the description, the 
same members as shown in the drawings of Embodiment 1 are indicated by the 
same numerals or characters, and the detailed description thereof will be 
omitted. 
A door structure of a vehicle according to this embodiment has a corner 
bracket 41 comprising a main panel 39 and an auxiliary frame 40 at a 
corner portion 8. Namely, similar to the structure described in Embodiment 
2, the corner bracket 41 is a one-plate structure thereby simplifying the 
structure. In this embodiment, the shapes of the main panel 39 and the 
auxiliary frame 40 are different from those of the above-mentioned main 
panel 35 and the auxiliary frame 36. More specifically, the auxiliary 
frame 40 is substantially L-shaped, and forms a U-shaped cross-sectional 
portion 41a for receiving a glass guide 7 therein together with an 
L-shaped portion 39b at a rear portion of the main panel 39. Similarly, a 
trim panel 38 is attached to a convex portion 39a of the main panel 39 
with a screw 33. 
Similar to Embodiment 1, a guide mechanism becomes unnecessary, the 
external appearance can be improved because deformation of a GRC portion 
21 of a first weather strip 19 hardly occurs, the wind-generated noise 
during traveling of the vehicle is hardly heard in the compartment, and 
the external appearance around the corner portion 8 can be improved. 
(Embodiment 4) 
A fourth embodiment of the invention will be described below with reference 
to FIGS. 11 and 12. For the convenience of the description, the same 
members as shown in the drawings of Embodiment 1 are indicated by the same 
numerals or characters, and the detailed description thereof them will be 
omitted. 
A door structure of a vehicle according to this embodiment has a corner 
bracket 45 comprising a main panel 42, an auxiliary frame 43 and support 
frame 44 at a corner portion 8 thereof. The front edge portion of the main 
panel 42 is bent and connected to a U-shaped cross-sectional portion 13 of 
a door sash 6. The auxiliary frame 43 has a U shaped cross section in 
which is fitted a glass guide 7, and is connected to a rear portion of the 
main panel 42. The support frame 44 has a holding portion 44a having a 
U-shaped cross section for holding a glass plate 46 at the outer portion 
thereof. The holding portion 44a is arranged at the inner side of a lip 
portion 30 of the glass guide 7 is covered with a covering member 44b. The 
glass plate 46 as an accessory is held by the holding portion 44a of the 
support frame 44 and a GRC portion 21 of a first weather strip 19. At the 
inner face of the main panel 42 is secured a trim panel 47 with a screw 
48. 
In the above-mentioned structure, the corner bracket 45 is a one-plate 
structure so as to be simple, and an outer face guide portion 21a and a 
lip portion 22 of the GRC portion 21 of the first weather strip 19 extend 
continuously even over the corner portion 8. Moreover, since the glass 
plate 46 is arranged in the same plane as the door window 4 at the corner 
portion 8, the continuity of the door window 4 with the corner portion 8 
exists so that the external appearance can be improved. Thus, the 
structure is suitable for achieving a flush surface. It should be noted 
that instead of the glass plate 46, a trim panel or a mirror base may be 
provided. 
Similar to Embodiment 1, a guide mechanism becomes unnecessary, the 
external appearance can be improved because deformation of the GRC portion 
21 of the first weather strip 19 hardly occurs, the wind-generated noise 
during traveling is hardly heard in the compartment, and the external 
appearance around the corner portion 8 can be improved. 
(Embodiment 5) 
A fifth embodiment of the present invention will be described below in 
accordance with FIGS. 13 and 14. For the convenience of the description, 
the same members as shown in the drawings of Embodiment 1 are indicated by 
the same numerals or characters, and the detailed description thereof will 
be omitted. 
A door structure of a vehicle according to this embodiment has a corner 
bracket 49 comprising an outer panel 49a, an inner panel 49b, and an 
auxiliary frame 50 having a U-shaped cross section at a corner portion 8. 
The front edge portion of the outer panel 49a is connected to a front 
portion of the inner panel 49b, and the front edge portion of the inner 
panel 49b is bent and connected to a U-shaped cross-sectional portion 13 
of a door sash 6. The rear edge portions of both panels 49a, 49b are 
connected to each other through the auxiliary frame 50. 
At the outer face of the outer panel 49a is provided a trim panel 51. The 
trim panel 51 has an attachment convex portion 51a near the central 
portion of the rear face thereof, and the attachment convex portion 51a is 
fixed to the outer panel 49a with a screw 33. The front edge portion of 
the trim panel 51 is inserted into a GRC portion 21 of a first weather 
strip 19, and the rear edge portion thereof is disposed at the inner side 
of a lip portion 30 of a glass guide 7. To the inner face of the inner 
panel 49b is attached a trim panel 52 by a screw 48. 
In the above-mentioned structure the corner bracket 49 has a closed 
cross-sectional structure, thereby exhibiting a high degree of strength. 
Furthermore, since an outer face guide portion 21a and a lip portion 22 of 
the GRC portion 21 of the first weather strip 19 extend continuously even 
over the corner portion 8, and since the trim panel 51 is arranged in the 
same plane as the door window 4, similar to Embodiment 4, a continuity of 
the door window 4 with the corner portion 8 exists so that the external 
appearance can be improved, thereby achieving a flush surface. It should 
be noted that, instead of the trim panel 51, a mirror base may be 
provided. 
Similar to Embodiment 1, a guide mechanism becomes unnecessary, the 
external appearance can be improved because deformation of the GRC portion 
21 of the first weather strip 19 hardly occurs, wind-generated noise 
during traveling of the vehicle is hardly heard in the compartment, and 
the external appearance around the corner portion 8 is improved. 
As mentioned above, the door structure of vehicle according to the present 
invention has a structure in which a vertically movable door window is 
arranged to the outside of a door sash forming a window space above a main 
door body, at the door sash is provided a weather strip for establishing a 
seal between the door sash and the door window, and a corner bracket is 
provided at a corner portion which is formed by the door sash and the main 
door body at an end portion of the door sash, wherein the weather strip 
has a glass guide portion which extends to an outer face peripheral edge 
portion of the door from an inner face peripheral edge portion thereof, in 
the glass guide portion a core material is embedded, the front end portion 
of the door sash extends forward along the upper edge portion of the 
corner bracket, the weather strip extends forward along the door sash, and 
another glass guide for guiding the front edge portion of the door window 
extends vertically along the rear edge portion of the corner bracket. 
Therefore, since the glass guide portion of the weather strip functions as 
a glass guide, it is not necessary to provide an additional guide 
mechanism for the door window, and deformation of the weather strip hardly 
occurs. Accordingly, the trouble of providing such a guide mechanism is 
obviated, the number of parts is reduced, and the external appearance is 
improved. Moreover, a restriction on the selection of the shape of the 
door sash is eliminated. A space to be formed between the door window and 
the door sash when the door window is closed is slight. Thus the 
wind-generated noise during traveling is hardly heard in the compartment 
thereby contributing to the quietness of the compartment. Moreover, it 
becomes possible to arrange the weather strip along, for example, a 
molding on the side of a car body in a constant and continuous state, so 
that it becomes possible to improve the external appearance around the 
corner portion in particular.
