PROBLEM TO BE SOLVED: To use door inside frameworks in front and rear doors on each side face on one side or the other side of a vehicle body as common parts, mass- produce the door inside frameworks to reduce manufacturing cost, increase the efficiency of assembly of various parts constituting a door main body, and composite individual parts efficiently and stepwise. SOLUTION: In a single vehicle body, mounting positions of various parts attached to the door inside framework A2 of the front door A1 on the side face on one side of the vehicle body, the door inside framework B7 of the rear door B6, the door inside framework C26 of the front door C25 on the side face on the other side of the vehicle body, and the door inside framework D31 of the rear door D30 and dimensions and shapes of the appearance of each door inside framework A2, B7, C26, D31 are unified and standardized to use them as common parts.
