- the frame structure 1 includes a base frame 2, a left side frame 5L integrally formed with a left front pillar 3L and a left roof pillar 4L, and a right side frame 5R integrally formed with a right front pillar 3R and a right roof pillar 4R.
- the left rear pillar 6L, the right rear pillar 6R, and the like are used as constituent members.
- the frame structure 1 joins the left side frame 5L erected on the base frame 2 and the upper part of the left rear pillar 6L, and the right side frame 5R erected on the base frame 11 and the right side frame 5R.
- Join the upper part of the rear pillar 6R connect the left side frame 5L and the right side frame 5R with the front roof beam 7F and the middle roof beam 7M, and connect the left rear pillar 6L and the right rear pillar 6R to the upper part. It is configured by connecting with a rear beam 8T, an intermediate rear beam 8mm, and a lower rear beam 8mm.
- the upper part of the left rear pillar 6L (the constituent member of the left side) and the left roof pillar 4L (the other constituent member) of the left side frame 5L are connected to the left connecting member 10L.
- the upper part of the right rear pillar 6R (the other component) and the right roof pillar 4R (the other component) of the right side frame 5R are joined via the left connecting member 10R.
- the left connecting member 10L and the right connecting member 10R are mirror-symmetrical with respect to the left and right central plane of the frame structure 1, and their basic configurations are different from each other. In the following, the configuration of the left connecting member 10L and the manner of joining the left rear pillar 6L and the left roof pillar 4L by the connecting member 10L will be described.
- the connecting member 10L is a member manufactured by pressing (sheet metal calorie) a metal plate (steel plate), and is joined to the left rear pillar 6L by welding. One end connecting end 11 and the other end connecting end 12 joined to the left roof pillar 4L by welding. It is also possible to manufacture the connecting member 10L using pig iron or steel, which is not a metal plate pressed. Also, in FIGS. 2 to 4, the arrow F points to the front of the frame structure 1.
- the one-side connection end 11 of the connecting member 10L has a corner including the outer surface of the left rear pillar 6L that also has a square steel pipe force, specifically, the front surface 6Lf and the outer surface 6Lo of the left rear pillar 6L.
