[Prior Art] Some vehicle bodies, such as automobiles, have a ventilator discharge path formed in a side door and a ventilator discharge hole formed in the rear end of the vehicle body of the door inner panel. Such a discharge path does not require various additional parts such as ornaments unlike the case where a discharge hole is provided in a pillar portion, etc., so it can be manufactured at low cost and is advantageous in terms of cost.

On the other hand, the inner panels of the side doors are designed to have a symmetrical shape on the front and rear sides of the vehicle body to the extent possible, with the aim of making them common between the left and right side doors.
Measures are being taken to improve productivity. This kind of door inner panel is said to have a common left and right type, and conventionally, (1) common external shape and aperture shape, and (2) common mounting holes for inside handles, regulator handles, etc. transformation is being carried out.

However, when attempting to standardize the left and right door inner panels having the ventilator discharge holes described above, it has been difficult to do so because the discharge holes are located on one side (the rear side of the vehicle body). Furthermore, in the inner panel of the side door, a hinge mounting hole must be formed on the end surface on the front side of the vehicle body, and a mounting hole for the door lock must be formed on the end surface on the rear side of the vehicle body. For this reason, such component mounting holes have not been standardized on the left and right sides.

[Problems to be Solved by the Invention] In consideration of the above facts, the present invention aims to further expand the range of common left and right vehicle door inner panels having ventilator discharge holes.

[Means for Solving the Problems] In the vehicle side door according to the present invention, the door main body is constituted by a door inner panel and a door outer panel, and each end of the door inner panel on the front side of the vehicle body and the rear side of the vehicle body The shape of the end face formed in the end face and the shape and position of the plurality of holes provided in this end face are symmetrical with respect to a center line extending in the height direction of the side door at the center in the length direction of the side door. It is characterized by

Similarly, vertically elongated oblong holes 8 and 9 having the same shape are formed at the same position. Furthermore, protrusions 4a and 5a on both end surfaces 4 and 5
Three oval holes 10a, 10b, 10c and 11a, 11b, 11c, which are long in the vehicle width direction, are formed symmetrically in the lower end surface portions 4c, 5c, respectively.

In the front end surface 4 of the vehicle body, upper and lower end surface portions 4b and 4c sandwiching the protrusion 4a function as hinge mounting surfaces, respectively, and reinforcing metal fittings 12 and 13 for hinge mounting are fixed to these end surface portions. Ru.
For this purpose, the holes 6a, 6b of the end face portions 4b, 4c are
The pitch between them and the pitch between the holes 10a, 10b, 10c are matched to the pitch between the holes 12a, 12b and the pitch between the holes 13a, 13b, 13c of the hinge mounting bolts drilled in the reinforcing metal fittings 12, 13, respectively. . Therefore, the pitch between the holes 7a, 7b in the end surface 5 on the rear side of the vehicle body and the pitch between the holes 11a, 1
The pitch between 1b and 11c is similarly set.

On the other hand, in the rear end surface 5 of the vehicle body, each hole 7
a, 7b, 9, 11a, 11b and 11c are
Functions as a ventilator outlet. Here, the holes 11a, 11b, and 11c, which are used as bolt holes for attaching reinforcing metal fittings when located on the front side of the vehicle body, are provided in order to secure the necessary ventilator discharge hole area.
As mentioned above, it is a long hole. Further, a bolt hole 14 and a notch groove 15 for attaching a door lock are formed in the protruding portion 5a of the end face on the rear side of the vehicle body.

3 and 4 show reinforcing metal fittings 1 on the hinge mounting surfaces 4b and 4c of the end surface 4 on the front side of the vehicle body, respectively.
2 and 13 are respectively fixed. As shown, the reinforcing metal fittings 12 and 13 are fixed to the surfaces 4b and 4c, respectively, by spot welding. As a result, holes 8 and 10a, 1
Unnecessary parts of 0b and 10c will be covered with these metal fittings. On the other hand, the rear end surface 5 of the vehicle body
Here, each hole 7, 7b, 9, 11a, 11b, and 11c functions as a ventilator outlet hole.
That is, as shown by the arrows in FIGS. 5 and 6, from the inside of the vehicle, the air passes between the door trim 16 and the inner panel 3, and passes through the service hole 17 having a check valve function formed in the inner panel.
