Description of the Related Art In a conventional vehicle body, when the vehicle body structure is an open type or a convertible type, particularly when a closed type body is modified into an open type or a convertible type body, it is very difficult to secure the body rigidity equal to that of a closed type body. As an example of a countermeasure, the front window frame, front and rear bulkheads, side sills, etc. were reinforced to increase rigidity. In recent years, even in the case of a closed type vehicle body, in order to effectively absorb the impact energy at the time of a frontal collision or a side collision, the plate of each part such as front and rear bulkhead, side sill, front pillar, center pillar, roof rail etc. This has been dealt with by increasing the thickness, increasing the shape of the step surface, or adding a gusset to the joint of the skeleton.

化を招くという問題点があった。When a closed type vehicle body is converted into an open type or convertible type vehicle body,
Due to a significant increase in body weight and a decrease in rigidity due to the aging of the body, a decrease in exercise performance and ride comfort is inevitable.
Further, even in the case of a closed type vehicle body, visibility in each direction is obstructed, and the weight of the vehicle body increases, so that fuel consumption deteriorates. Regardless of the open, convertible, or closed type vehicle body shape, many vehicles require an opening / closing door for occupants to get on and off. A large opening is provided from the side sill to the upper roof rail, and the door is pivoted to the vehicle body with a door hinge and a door catch so that it can be opened and closed. The main purpose was to keep it at a low level, and even with the side impact bar, it did not sufficiently contribute to improving the rigidity of the vehicle body. Furthermore, the large opening cannot absorb the impact of the side collision sufficiently,
It is difficult to transmit the impact to the pillars around the door or the roof rail nerd sill, so the impact load concentrates,
There were disadvantages such as a large deformation of the cabin. Therefore, in order to address the above-mentioned disadvantages, the front and rear bulkheads, side sills, front window frames, front pillars and center pillars with long attachment spans, and expanded roof rails, etc. Furthermore, the rigidity of the vehicle body must be ensured by increasing the thickness of the steel plate to be used. As a result, there is a problem that the steering performance and fuel consumption are deteriorated due to an increase in the vehicle body weight.

ている。According to the present invention, the cross-sectional shape of each frame of the vehicle body, such as the front and rear bulkheads, side sills, front window frames, front pillars, center pillars, and roof rails, and the steel plate used are unnecessarily enlarged or thickened. It aims at optimizing the balance between the respective skeletons without providing a vehicle having a highly rigid and lightweight vehicle structure.

やすくなる。At the time of a frontal collision and a rearward collision, after the impact load is absorbed by the collision portion, the impact load is dispersed not only to the side sill and the roof rail on the non-collision side, but also to the skeleton which is arranged and fixed inside the door. Since the transmitted impact load is absorbed and transmitted to the non-collision-side skeleton, the deformation of the passenger compartment is further minimized, so that the living space of the occupant is secured. Also, on the other side of the door internal skeleton, a robust third skeleton joining head is crowned with a robust third skeleton joining cap, and a skeleton joining auxiliary plate at the door side skeleton end,
Since both of the skeleton joining auxiliary plates of the other vehicle body side skeleton are in surface contact, the probability that the door rear side surface contacts the vehicle body side skeleton surface opposite to the door rear side surface can be reduced,
After a collision, the probability that the door will open increases, making it easier for the occupants to evacuate out of the vehicle.
