PROBLEM TO BE SOLVED: To enable an assembly worker to recognize whether or not assembly has been erroneously performed in a stage before inserting the shaft part of one door to the hole part of the other door when making it possible to assemble two or more types of door units to a common casing.SOLUTION: The shaft part 321b of a driver's seat side door 321 of an independent operation door unit is configured such that, in the state of being inserted to the hole part of a front passenger seat side door of the independent operation door unit, the driver's seat side door 321 and the front passenger seat side door are relatively turnable. On the inner surface of the hole part 324b of the front passenger seat side door 324 of a linked door unit, a projection part 324e is formed. The shaft part 321b of the driver's seat side door 321 of the independent operation door unit is made smaller in a diameter than the shaft part of the driver's seat side door of the linked door unit. The projection part 324b is formed so as to block insertion of the shaft part 321b of the driver's seat side door 321 of the independent operation door unit into the hole part 324b of the front passenger seat side door 324 of the linked door unit. |
