The horizontal bones 21 of the window 3 are formed to have substantially the same length as the length of the window 3 in the longitudinal direction of the vehicle body. The parts are superposed on both sides of the side pillar 24 between the side windows 2 and 2 flush with each other, and these are integrally connected by using the same band-shaped gusset 17 as before.

The side column 6 and the lateral bones 11 and 21 on the door pocket 5 side are
A pair of parallel rims 6a, 6a, 11a, 11a, 21a
Of the rims 6a, 6a, 11a, 11a, 21a, 21a, flanges 6c, 6c, 11c, 11c, 21 outside the other ends of the rims 6a, 6a, 11a, 11a, 21a, 21a.
c, 21c are extended, and the side pillars 6 and the lateral bones 11 of the door pocket portion 5 are formed in the same hat-shaped cross section with a reduced thickness in the vehicle width direction, whereas the window is The side pillars 24 between the side bones 21 of the part 3 and the side windows 2 and 2 are formed in a hat-shaped cross section having a greater thickness in the vehicle body width direction.

For example, the lateral bone 11 of the door pocket 5 and the side pillar 6 on the side of the door pocket 5 have a thickness in the vehicle width direction of 40 mm.
mm is used, and the lateral bone 21 of the window portion 3 and the side column 24 between the side windows 2 and 2 have a length of 70 mm, which is approximately twice as long as the conventional receiving bone is provided inside the vehicle body. ~ 80mm
Of about the same thickness as the horizontal bone 21 of the window 3
The conventional receiving bone is omitted from the side column 24 between the side windows 2 and 2.

The side post 6 on the side of the door pocket 5 is provided with flanges 6c, 6
c is disposed between the window portion 3 and the door pocket portion 5 with the c facing the outside of the vehicle body, and the lateral bones 11 and 21 of the window portion 3 and the door pocket portion 5 are
Flanges 11c, 1 on the inside of the vehicle body of the flanges 6c, 6c
The ends of 1c, 21c, and 21c are overlapped substantially flush with each other and joined by welding or the like. Due to this joining, the webs 6b and 11b of the side bones 6 of the side column 6 and the door pocket portion 5 are located on the same plane, and the web 21b of the side bones 21 of the window portion 3 is located with a step inside the vehicle body. Flange 6 of side pillar 6
A reinforcing plate 25 for joining the two lateral bones 11 and 21 is stretched between c and 6c so that expansion and contraction in the vehicle longitudinal direction can be effectively prevented.

The first gusset 22 includes one side piece 22a and another side piece 22b, which are parallel and have different phases, and are connected to the transverse bone 11,
A crank-shaped strip connected by a connecting piece 22c having a length corresponding to the step of the connecting portion between the side 21 and the side pillar 6, and connecting the middle connecting piece 22c to the vicinity of the end of the horizontal bone 21 of the window 3 , The side piece 22a is connected to the side column 6 and the web 6b of the transverse bone 11,
11b and joined by welding or the like.

The second gusset 23 has a shape in which a triangular plate 23a and a deformed square plate 23b are connected in a rectangular fold, and one triangular plate 23a is attached to the rim 21a of the lateral bone 21 of the window 3 and the other square plate 23b Are superimposed on the webs 6b of the side columns 6, respectively, and these are joined by welding or the like.

The welding used for joining the above-described transverse bones 11 and 21 to the first and second gussets 22 and 23 is, for example, spot welding or plug welding. In addition, bolts and nuts, rivets, adhesives, etc. Can be used.

As described above, in the embodiment, the transverse bone 2 of the window 3 is formed.
1 is thicker in the width direction of the vehicle body than the lateral bones 11 of the door pocket part 5, and the first and second gussets 2
2 and is heavier than the lateral bone 11 of the door pocket part 5 and the lateral bone 21 of the window part 3 having a longer span is
Since the two second gussets 23, 23 are used to integrally connect the side pillars 6 with each other, the rigidity of the side structure 20 can be sufficiently secured despite the large opening of the side window 2, and the riding comfort can be improved. Thus, it is possible to improve the mounting strength of interior parts such as tables and ashtrays.

Further, compared with the conventional one in which the receiving bone of another part is joined by welding or the like to the inside of the vehicle at the lateral bone of the window part,
The rigidity of the thick transverse bone 21 in the width direction of the vehicle body can be effectively utilized, and the number of work steps and the number of parts can be reduced, and the cost can be reduced.

In particular, in this embodiment, the first gusset 22 is formed in a crank shape corresponding to the step of the connecting portion between the lateral bones 11 and 21 and the side pillar 6, and the second gusset 23 is formed by rectangular folding.
Since the shape which wraps up the step of the connection part between the horizontal bones 11 and 21 and the side column 6 is extremely high, the side structure 20 has extremely high rigidity. It is possible to effectively prevent adverse effects such as stress concentration caused by a sudden change in rigidity.

d is different from the first embodiment.

The horizontal bone 21 of the window 3 is formed by superposing the ends of the flanges 21c, 21c substantially flush with the inside of the vehicle body of the flange 6c of the side column 6 on the window 3 side. 11
Is joined to the inside of the vehicle body of the flange 6c of the side pillar 6 on the side of the door pocket section 5 by welding or the like by overlapping the ends of the flanges 11c, 11c substantially flush with each other.

In the first gusset 30, the connecting piece 30c is disposed near the end of the horizontal bone 21 of the window portion 3 and the one side piece 30a is connected to the web 11b of the horizontal bone 11 and both side columns 6,6. , 6b, 6
b, the reinforcing pieces 30d, 30d are inserted between the side columns 6, 6, and the other side piece 30b is superimposed on the web 21b of the horizontal bone 21 of the window 3. Then, the one side piece 30a and the other side piece 30b of the first gusset 30 are connected to the transverse bones 11 and 21 and the webs 11b of the side pillars 6 on the door pocket part 5 side,
21b and 6b are respectively joined by welding or the like, and one side piece 30a of the first gusset 30 and the web 6b of the side column 6 on the window 3 side are joined by welding or the like.

The two second gussets 23, 23
As in the above-described first embodiment, the side column 6 and the lateral bone 2 on the window 3 side are used.
1 and is used to connect one of the triangular plates 23a to the transverse bone 21.
The other square plate 23b is overlapped with the web 6b of the side column 6 on the window portion 3 side, respectively, and the one triangular plate 23a and the rim 21a of the horizontal bone 21 are joined by welding or the like, and Square plate 23b and web 6 of side column 6 on window 3 side
b by welding or the like, and both lateral bones 11 with a step
21 and the side columns 6 and 6 are firmly connected together with the first gusset 30.

The third embodiment shown in FIGS. 7 to 9 shows a structure in which the lateral bones 21 having different thicknesses in the vehicle body width direction and the studs 9 are connected to the window 3 of the side structure. Since this embodiment is shown in FIG. 2 used for describing the first embodiment, FIG. 2 will be referred to as appropriate.

The stud 9 disposed below the side window 2 has a hat-shaped cross section composed of rims 9a, 9a and webs 9b and flanges 9c, 9c, and has a thickness in the vehicle width direction of the side pillar 6.
The same as the first and second embodiments, 70 to 8 are used for the transverse bone 21.
Thickness of about 0 mm is used.
The step-like connecting portion between the shaft and the lateral bone 21 is connected using a third gusset 40.

The third gusset 40 comprises a pair of parallel rims 40a, 40a, a web 40b connecting one end of the rims 40a, 40a, and a connecting piece 40c protruding from one side edge of the web 40b. Has become. When the rims 40a, 40a of the third gusset 40 are joined to the rims 9a, 9a of the stud 9 at the end opposite to the web 40b, the connecting piece 40c projecting from the web 40b is
