3 and the running bogie 2 are fixed, and even if the car body 1 protrudes from the running bogie 2 in the front and back, the car bodies 1 on the front and rear running bogies 2 will not be damaged by bumping into each other. There isn't.
このようにして車体１はその向きを90度ずつ変
化させて移動することが可能であり、また車体１
を昇降させることも可能であるので、車体１に組
付けるべき部品に応じて車体１の向きおよび高さ
を選択することができ、組付作業能率が向上す
る。 In this way, the car body 1 can move by changing its direction in 90 degree increments, and the car body 1
Since it is also possible to raise and lower the vehicle body 1, the orientation and height of the vehicle body 1 can be selected depending on the parts to be assembled to the vehicle body 1, and the efficiency of the assembly work is improved.

Effects of the Invention As described above, according to the present invention, a traveling cart capable of mounting a vehicle body and traveling in the transport direction is placed in a pit provided at a conversion position set midway along the transport direction. A rotary table to be obtained is housed in a manner that can be raised and lowered, and is provided with an elevating drive means for raising and lowering the rotary table, and a rotation drive means for driving the rotary table to angularly displace it by 90 degrees around a vertical axis, The traveling cart includes a plurality of first wheels arranged in two rows that are rollable on a first traveling road surface that extends along the conveyance direction and passes through the conversion position, and a plurality of first wheels that are arranged in two rows and are arranged at a position higher than the first traveling road surface. A plurality of second wheels arranged in two rows and capable of rolling on a second running road surface extending along the direction and passing through the conversion position are arranged such that their parallel directions are orthogonal to each other and their ground contact levels are different from each other. Since it is installed along the conveyance direction, the traveling trolley can be rotated around the vertical axis at the conversion position along the conveyance direction.
In addition to changing the direction of the vehicle by 90 degrees, it is possible to switch between running the running bogie using the first wheel and running the running bogie using the second wheel.
It becomes possible to transport the parts at different degrees, which facilitates the work of assembling parts onto the vehicle body, and facilitates automation of the work of assembling parts.
