The end portion on the door end 1a side has a U-shaped frame portion 11 and the end portion on the door bottom 1b side A locking groove 12 is provided. The thickness t2 of the front plate portion p2 on the door end 1a side and the door butt 1b side facing the hollow portions 10E and 10F is thicker than the thickness t1 of the front plate portion p1 on the center side facing the hollow portions 10A to 10D. It has become. Further, the partition walls 13A on both sides of the central hollow portion 10A and the partition walls 13B between the hollow portions 10B and 10C are thickened as the screw seat thick portions 14 at both ends in the door thickness direction. On the other hand, the partition wall 13C between the hollow portions 10C and 10D and the partition wall 13D between the hollow portions 10D and 10E are entirely thin and have no thickness change. The partition wall 13E between the hollow portions 10E and 10F has a narrow width inside and outside the vehicle due to the narrow end shape of both the hollow portions 10E and 10F.

  On the door tip 1a side of the door main body 1, the door tip rubber 4 inserts the base portion 4a into the U-shaped frame portion 11 of the aluminum extrusion mold S1, and the neck portion 4b protrudes from the U-shaped frame portion 11 so as to face the door. The strips 11a and 11a are fitted between the strips 11a and 11a. Further, on the door bottom 1b side of the door body 1, a strip-shaped windshield rubber 6 that is continuous in the vertical direction is engaged with the locking protrusion 6a that is continuously provided on the inner surface side of the aluminum extrusion mold material S1. It is inserted into the groove portion 12 and fixed with the one side edge 6b protruding to the outside of the vehicle, and the upper and lower door butt receiving rubbers 5 are located on the windshield rubber 6 as shown in FIG.

A U-shaped hand frame material 7 is fitted and fixed by bonding.

  As shown in the cross section of FIG. 2 (b), the window W is formed by cutting the central side including the hollow portions 10A to 10D of the aluminum extrusion mold S1 with a predetermined vertical width, so that the window center is located at the outer periphery of the vehicle. A window opening portion 15 having a flange portion 15a for preventing detachment projecting to the side is formed, and a window edge 2A is fitted and screwed to the window opening portion 15, and a glass single plate G1 is attached to the window edge 2A. Is fitted.

  The window edge 2A is made of an aluminum extruded mold that is formed in an annular shape in accordance with the peripheral edge of the window opening 15, and has a U-shaped base frame 2a whose cross section opens to the outside of the window, and the vehicle inner outer edge of the base frame 2a. And a locking frame portion 2b having an L-shaped cross section extending from the vehicle interior to the vehicle inner side. The base frame portion 2a is fitted to the vehicle inner side of the flange portion 15a of the window opening 15, and the locking frame portion. 2b is configured to engage with the vehicle interior edge corner of the window opening 15. Then, on both the left and right sides of the window opening 15, as shown in FIG. 2 (b), the locking frame of the window edge 2 A joined to the partition wall 13 D exposed to the window opening 15 and continuing vertically. The part 2b is screwed with a tapping screw 21.

  On the other hand, on both the upper and lower sides of the window opening 15, as shown in FIG. 4, screw holes are formed in the thick portions 14 for screw seats on the inner sides of the respective partition walls 13 A and 13 B appearing in the window opening 15. As shown in FIGS. 3 (a) and 3 (b), a screw 22 is screwed into each screw hole 14a through a locking frame portion 2b of the window edge 2A. 2A is screwed.

  The glass single plate G1 has a spacer on the inner side of the locking frame portion 2b of the window edge 2A via the packing 24 with respect to the locking frame portion 2b and between the base frame portion 2a of the window edge 2A. 23 and an adhesive 25. A packing 26 is also inserted between the inner edge of the base frame portion 2a of the window edge 2A and the leading edge of the flange portion 15a of the window opening 15.

  As shown in FIG. 5 (a), at the upper end portion of the door body 1, a door pulley mounting frame 30 made of an aluminum extrusion mold material having an open U-shaped vertical section is fitted into the cut portion inside the top portion of the aluminum extrusion mold material S1. Screwed. And each bracket 31 which pivotally supported the door pulley 3 has the base part 31a bent horizontally on the door roller mounting frame 30 via the steel liner 32, and the bolt 34 penetrated from the upper side is attached to the door wheel mounting frame. The door body 1 is fixed to the door body 1 by screwing and tightening to a nut 35 disposed in the door 30. The bracket 31 is pivotally supported with a door roller 3 and a pressing roller 33 that comes into contact with the guide rail R on the vehicle body from below. On the other hand, at the lower end portion of the door body 1, an angle member 8a along the horizontal direction and a groove 8b open downward are fitted and screwed to the cut portion inside the bottom portion of the aluminum extrusion mold material S1. Further, an antifouling plate 9 is stretched on the lower end of the door body 1 on the vehicle inner side.

  In the vehicle door having the above-described configuration, the door body 1 from the door tip 1a to the door butt 1b is configured by the aluminum extrusion mold material S1, and does not have front and back face plates like a conventional general vehicle door. Eliminating the need to join the face plates, it can be assembled and manufactured efficiently and in a short time, and the cost can be reduced by reducing the number of man-hours. At this time, it is easy to increase the dimensional accuracy. And the door main body 1 has a plurality of hollow portions 10A to 10F arranged along the width direction, is lightweight, and is made of an incombustible aluminum extruded mold material, so that it has excellent safety and good appearance. In addition, since almost the entire door is made of aluminum, recyclability is also improved.

  In addition, since this vehicle door has the thick portion 14 for screw seats on the partition walls 13A and 13B between the hollow portions 10A-10B and 10B-10C facing the window opening 15, these screw seats are provided. The window edge 2A can be easily screwed to the window opening 15 on both the upper and lower sides using the thick wall portion 14 and the window edge 2A can be stably and firmly attached. Due to the presence of the portion 14, the rigidity on the center side in the width direction of the door body 1 is increased, so that the durability reliability is also improved. On the other hand, if the partition wall between the hollow portions facing the window opening 15 does not have the screw seat thick portion 14, the window edge 2A is screwed to the left and right partition walls 13D that are continuous in the vertical direction on both the left and right sides. Even if it is possible, screwing to the partition wall is impossible on both the upper and lower sides. Therefore, in the configuration not having the screw seat thick portion 14 described above, in order to make the window edge 2A stable and strong, the screwed portions on the left and right sides are increased, and the aluminum extrusion mold material is provided on the upper and lower sides. However, the appearance of the window W is deteriorated, and the rigidity of the door body 1 in the center in the width direction is also reduced.

  Furthermore, in the aluminum extruded mold S1 constituting the door body 1 of the above embodiment, the thickness t2 of the front plate portion p2 on the door end 1a side and the door bottom 1b side is larger than the thickness t1 of the front plate portion p1 on the center side. Since it is thick, it has a hollow thick plate shape and is light overall, and even if there is a large cut portion for the window portion W, both sides become highly rigid and excellent in strength. Further, the window opening 15 has an advantage that the glass single plate G1 having different thickness can be surely fitted by using the flange portion 15a protruding from the peripheral edge to the window center side as a stopper. The ratio of the thickness t2 / t1 is generally about 2 to 5, and t1 is preferably about 1 to 4 mm, although it varies depending on the type of vehicle to which the vehicle door is applied and the specifications such as the attachment site and the door size. It is.

  In the window opening 15 in the vehicle door of the present invention, instead of the window edge 2A for fitting the glass single plate G1 exemplified in the above embodiment, for example, as shown in FIGS. 6 (a) and 6 (b) As in the embodiment, the window edge 2B for fitting the multilayer glass G2 may be screwed. The window edge 2B is made of an aluminum extruded mold having an L-shaped cross section that is bent in an annular shape in accordance with the peripheral edge of the window opening 15, and the L-shaped bent portion covers the edge of the window opening 15 on the vehicle inner side. Thus, it is arranged in the window opening 15. On both the upper and lower sides of the window opening 15, as shown in FIG. 6A, the end faces of the partition walls 13 </ b> A and 13 </ b> B that appear in the window opening 15 are provided in the thick portion 14 for the screw seat inside each vehicle interior. The window edge 2B is screwed into the screw hole 14a via a screw 22. On the other hand, on both the left and right sides of the window opening 15, as shown in FIG. 6B, the window edge 2B joined to the partition wall 13D exposed to the window opening 15 and continuing vertically is tapped by a tapping screw 21. Screwed in with. The multilayer glass G2 is fitted inside the window edge 2B via a spacer 23 and an adhesive 25. Even in the multi-layer glass G2, the peripheral edge is located on the vehicle inner side of the flange portion 15a of the window opening portion 15, so that the detachment preventing function by the flange portion 15a is exhibited.

  In the said embodiment, although the door main body 1 illustrated what comprised the single aluminum extrusion mold material S1, in this invention, this door main body 1 is comprised from the some aluminum extrusion mold material which divides | segments a door width direction. Also good. That is, according to such a divided configuration, the individual aluminum extrusion mold material becomes narrow and can be manufactured at a low cost by a relatively small aluminum extrusion device, so that even a wide vehicle door can be manufactured at a low material cost. There is.

  The dividing position in the door width direction is not particularly limited, and may be set as appropriate according to the door specifications and workability. However, as shown by the one-dot chain line in FIG. And the division by the left and right side positions C2 and C2 of the window W are particularly suitable. That is, in the structure which divides into right and left by the center position C1, compared with the case where the door main body 1 is comprised with a single aluminum extrusion mold material like the said embodiment, the cutting process for forming the window opening part 15 is carried out. There is an advantage that becomes easier. Moreover, in the structure which divides | segments into a center part and right-and-left both sides by the right-and-left both-sides position C2, C2 of the window part W, the aluminum extrusion mold material for center parts has only the edge part of the window opening part 15 side of the said window opening part 15 side. It only has to be cut into a shape that fits the upper and lower edges, and in addition to being easy to process, there is no need to greatly cut the mold material for the window opening 15, so there is very little material waste. Thus, the material cost can be reduced accordingly.

  FIG. 7 shows an example of a divided configuration by one or both of the center position C1 in the door width direction and the left and right side positions C2, C2 in the door body 1 of the vehicle door according to the present invention. The door main body 1A shown in FIG. 1 (a) forms the same cross section as the aluminum extrusion mold material S1 of the above-described embodiment after being connected.
