【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged vertical cross-sectional view of a main part of the vehicle door (showing one of the double doors for entrance and exit) shown in FIG. 3, and FIG. 2 is an enlarged horizontal cross-sectional view of the door.

In these drawings, the vehicle door has a door body 1, and the door body 1 includes an upper horizontal frame member 2 made of aluminum or its alloy, a lower horizontal frame member 3 made of stainless steel, The front end side vertical frame member 4 is made up of stainless steel door end side and rear end side vertical frame members 4 and 5, and steel front end side and rear end side reinforcing frame members 6 and 6, respectively. The door end rubber 7 is attached via a rubber holder 8. Also, on the inside and outside surfaces of the door body 1, a stainless steel inside plate 9 and an outside plate 10 are mounted, and inside the outside plates 9 and 10 inside, a core material 12 made of paper honeycomb is loaded. In addition, glass windows 13 are provided on the upper sides of the side plates 9 and 10.

As is apparent from FIGS. 1 and 3, the lower horizontal frame member 3 includes an upper portion 3a having an upward U-shaped cross section and a lower portion 3b having a downward U-shaped cross section. Door inner members 14, 14 are arranged in a fitted state at both ends of the lower portion 3b of the lower horizontal frame member 3 in the longitudinal direction (door moving direction).

Each of the door guide members 14 is made of nylon having excellent wear resistance and sliding property, and mechanical properties such as compression, tension, bending, etc., and as shown in FIG. And the side wall portions 16 and 16 are formed in a downward U-shaped cross section, and if the width W between the side wall portions 16 and 16 (FIG. 4) is, for example, about 10 mm, the height T ( Figure 4) is set relatively small, for example, about 14 mm, so that it can withstand the lateral pressure (door width direction) during use.

On the surface of the upper wall portion 15 of the door guide member 14 facing the lower horizontal frame member 3, that is, on the upper surface of the upper wall portion 15, as a groove engaging portion, a groove strip having a substantially T-shaped cross section is formed. 17 is formed over the entire length of the door inner member 14 in the longitudinal direction.

On the lower surface of the lower wall portion 3 c of the lower horizontal frame member 3 facing the upper wall portion 15 of the door guide member 3, a convex cross-section locking portion fitted into the groove 17 is provided, and the cross-sectional shape thereof is substantially the same. The T-shaped ridge 18 is formed to be substantially the same as or slightly longer than the groove 17.

Reference numeral 19 denotes a skirt plate whose upper portion overlaps with the lower end portion of the vehicle inside plate 9 and is fixed to the side surface of the lower horizontal frame member 3 by upper and lower screws 20 and 21. The lower screw 21 is also screwed into the door guide member 14 and also serves as a retaining portion in the longitudinal direction of the door guide member 14. In the figure, reference numeral 24 is a screw hole formed in the side wall portion 16 of the door guide member 14 to which a screw 21 for retaining is screwed.

When attaching the door guide member 14 to the lower horizontal frame member 3 of the door body 1, while inserting the groove 17 of each door guide member 14 into the protrusion 18 of the lower horizontal frame member 3 from the longitudinal direction, The door guide member 14 is fitted into a predetermined portion of the lower horizontal frame member 3.

Then, the skirt plate 19 is fixed to the lower horizontal frame member 3 by the upper and lower screws 20 and 21. At this time, the screw 21 is screwed into the door guide member 14 as well, so that the longitudinal movement of the door guide member 14 is blocked and the screw 21 is prevented from coming off. The hem plate 19 allows the vehicle inside plate 9 to be maintained at a constant height when the height of the door body 1 is increased.

In use of the vehicle door configured as described above, as shown in FIG. 1, each door guide member 14 has a rectangular cross section formed on the vehicle floor surface 22 along the door moving direction. The guide rail 23 having a shape is lightly engaged in a state of being fitted over the guide rail 23, and the door is opened and closed by being guided by the guide rail 23 via the door guide member 14.

When the door guide member 14 is attached to the lower horizontal frame member 3, the groove 17 on the door guide member 14 side may be fitted into the protrusion 18 on the lower horizontal frame member 3 side. The work is easier than the above. In addition, even when the vehicle is shaken or vibrated when the vehicle is running or when the door is opened or closed, it does not loosen like a screw. Therefore, there is no problem that the opening and closing of the door is hindered due to screws falling off. In other words, it is possible to maintain the stable opening / closing function of the door for a long period of time by the firm mounting state of the door guide member 14.

In the embodiment described above, the door guide member 14 is made of nylon, but not limited to nylon, urethane rubber or SUS304 may be used.

Further, in the above-described embodiment, the groove engaging portion formed on the upper wall portion 15 of the door guide member 14 is the groove portion 17 having a substantially T-shaped cross section, and the lower wall portion of the lower horizontal frame member 3 is also formed. Although the ridge locking portions formed on 3c are illustrated by the ridges 18 each having a substantially T-shaped cross section, the shape is not limited to these shapes and, for example, as a ridge engaging portion as shown in FIG. Arbitrary shapes can be adopted, such as forming a groove strip 51 having a substantially triangular cross section and forming a projecting strip 52 having a substantially triangular cross section as a protrusion locking portion.

Further, in the above-mentioned example, the recessed line engaging portion 17 (51) is formed on the upper wall member 15 of the door guide member 14, and the protruding line locking portion is formed on the lower wall portion 3c of the lower horizontal frame member 3. Although 18 (52) is formed, it is also possible to adopt an upside down configuration.

It should be noted that, in the above-described embodiment, the description has been made by assuming that the retainer portion of the door guide member 14 also serves as the screw 21 for fixing the hem plate 19, but both ends of the convex locking portion 18 (52). The portions may be respectively crimped, and the crimped portion may constitute the retaining portion. Alternatively, a means for interposing an adhesive between the door guide member 14 and the lower horizontal frame member 3 may be used. .
