The upper and lower bulk members are connected to each other by the link mechanism.

The invention according to claim 3 is a side portion of an open car in which a bulk member for bridging and connecting the pillar outer and the pillar inner is disposed at the upper and lower portions in the center pillar, and a roof opening / closing link mechanism is disposed on the vehicle interior side of the pillar inner. In the body structure,
The upper and lower bulk members are connected to each other by the link mechanism.

According to the first aspect of the present invention, since the link mounting bracket is formed in a box shape, the construction rigidity of the link mechanism can be ensured, and the roof can be opened and closed smoothly.

The link mounting bracket is disposed between the upper and lower bulk members that bridge and connect the pillar outer and inner, and is connected to at least one of the bulk members, so that the rigidity between the upper and lower bulk members of the center pillar can be improved. The amount of deformation entering the vehicle interior side of the center pillar during a side collision can be suppressed.

In addition, since an essential link mounting bracket is used for the roof opening / closing type open car, the above-described effects can be obtained without causing an increase in cost, weight, and productivity.

In the invention of claim 2, in addition to the structure of claim 1, the upper and lower bulk members are bridge-coupled by a link mechanism, so that the collision load on one of the bulk members can be transmitted to the other bulk member, The rigidity between the upper and lower bulk members of the center pillar can be greatly improved, and the roof can be opened and closed more smoothly by greatly improving the rigidity of the link mechanism, which can further suppress the deformation amount of the center pillar.

In the invention of claim 3, since the upper and lower bulk members are bridge-coupled by a link mechanism having a certain degree of rigidity, the rigidity between the upper and lower bulk members of the center pillar can be improved, and any of the upper and lower bulk members can be improved. Even when a side collision load is input to one of the two, the load is also transmitted to the other bulk member, so that the amount of deformation entering the vehicle interior side of the center pillar at the time of the side collision can be further suppressed.

In addition, since the upper and lower bulk members are bridge-coupled by the link mechanism, the rigidity of the link mechanism itself can be utilized to improve the building rigidity, and the roof can be opened and closed smoothly.

In addition, since an essential link mechanism is used for the roof opening / closing type open car, the above-described effects can be obtained without causing an increase in cost, weight, and productivity.
