  By the way, from the viewpoint of reducing the weight of the vehicle, as shown in Patent Documents 1 to 3, it is preferable to employ a resin material having a specific gravity lower than that of a metal material as a vehicle body member of the vehicle.

  However, as the proportion of the resin material used for the vehicle body member increases, the rigidity of the vehicle body decreases, so that there is a problem in that the vehicle body is easily deformed or vibrated while the vehicle is running and the ride comfort of the vehicle is deteriorated.

  In particular, when a monocoque body structure (a structure in which the body and chassis frame are integrated), which occupies the current mainstream, is adopted as the vehicle body structure, the suspension and engine are directly attached to the body. On the other hand, if the resin vehicle body member is applied, the above-described problems of vehicle body deformation and vibration during vehicle travel become more prominent.

  Therefore, the vehicle body of the vehicle is divided into a vehicle body lower body and a vehicle body upper body as shown in Patent Document 2, and a vehicle body lower body (platform portion) with a large external force input from the road surface while the vehicle is running, It is conceivable that the metal member is made of a highly rigid metal member while the other parts are made of a resin material having high lightness.

  In order to employ such a divided structure, a technique for assembling the divided vehicle body upper body and vehicle body lower body with high rigidity and high accuracy is required.

  However, in the above-mentioned Patent Document 2, since the upper cabin portion is configured by a joined body of the vehicle body front body and the vehicle body rear body, the upper body with respect to the underbody is caused by an assembly error between the two. There is a problem that the assemblability of the cabin is deteriorated.

  Moreover, in the thing shown in the cited reference 2, since the upper cabin part and the underbody are bonded and bonded via the flange part, there is a problem that the connection rigidity between the two is reduced as compared with the case of welding or the like. is there. In addition, as a result of forming the flange portion in the upper cabin portion, there is a problem that the shape of the upper cabin portion is complicated and its formability is deteriorated.
