A vehicle assembling method includes the steps of assembling a lower body shell a including underbody portion having a front floor and front body portion, assembling an upper body shell, including a roof member and right and left body side panels, and assembling the upper body shell and the lower body shell, moving rearward the lower body shell relative to the upper body shell, and engaging transverse opposite side ends of the lower body shell with lower end portions of the upper body shell to join the lower body shell with the upper body shell. The under body portion can be readily joined with the upper body shell, improving the workability of the joining operation. The structure of joint portion thereof can be simplified with a desirable sealing.

Vehicle assembling method

The method involved in the present invention is directed to the coating step where an assembled unit of the upper vehicle body and the under vehicle body is coated and the upper vehicle body section is separated from the under vehicle body after coating. In the vehicle body assembly step, the vehicle body is loaded on a jig unit disposed so as to be movable through stations located along the vehicle body assembly line. Upon loading the upper vehicle body on the jig unit, the vehicle body is aligned with the jig unit on the basis of an inner member of a member for structuring the vehicle body with the aid of an aligning unit mounted to the jig unit. After coating the assembled vehicle body unit, the unit is divided into the upper vehicle body and the under vehicle body, which are then processed in separate mounting steps. After mounting various parts to each of the upper vehicle body and the under vehicle body in their own mounting lines, the upper vehicle body is combined with the under vehicle body. The lower part unit is then mounted to the vehicle body assembly or mounted to the under vehicle body prior to the assembly of the under vehicle body with the upper vehicle body.

Method for the assembly of automotive vehicles

Disclosed is the method for coating automotive vehicle bodies, in which the upper vehicle body section and the floor member, constituting a vehicle body of the automotive vehicle, are conveyed simultaneously by the same conveying device at least up to the undercoating step for coating them with an undercoating paint. After the undercoating step, the floor member are separated from the upper vehicle body section at an appropriate timing, followed by separate conveyance to the following step.
