It is possible to flexibly cope with the work stoppage in the case.

In the above described vehicle parts assembling apparatus, the rail 34 for guiding the bogie rollers 33 is used as the moving mechanism of the work chair 59 with respect to the ceiling and the floor.
It is only necessary to provide a configuration in which the air circuit 97 and the electric wiring can be connected to the outside of the carriage 29,
Unlike the conventional case, large-scale construction work is not required for the ceiling and the floor, and it is possible to flexibly cope with a change in composition to accommodate different types of vehicles.

Also, during operation, the carriage 29 moves in synchronization with the vehicle body 27, so that the second arm 51 is located in the opening 27b of the vehicle body 27 even when the worker has entered the vehicle interior. Interference with the center pillar is avoided, and deterioration of the quality of the vehicle body 27 is prevented. As shown in FIG. 3, the movement of the worker in and out of the passenger compartment can be performed on the vehicle body 27 with the door attached since the arm portion moves in an arc.
