It is provided so as to be movable via 4, 4 and one power trolley device 5. And each transport rail 3
Has an I-shaped cross section having a main portion 3a extending in the vertical direction and vertical rail portions 3b and 3c that are continuously provided above and below the main portion 3a and are wide in the horizontal direction.

The hanger means 2 has frame members 2a, 2a extending in the front-rear direction of the vehicle body. The front and rear portions of the left and right frame members 2a, 2a are located above and below the cowl box (or hood) of the vehicle body W. The front and rear connecting portions 2b and 2c are connected to each other above the trunk room. Further, locking members 2f, 2f each having a locking portion 2e at the lower end are rotatably supported in the front-back direction on a rotation shaft 2d that is fitted onto each frame member 2a and rotatably supported. It can be opened and closed in any direction. The front and rear locking members 2f, 2f are connected to each other by a connecting member 2g extending in the front-rear direction.

As shown in FIG. 2, the power trolley device 5 includes upper, middle and lower support portions 11a, 11b, 11 as shown in FIG.
A drive unit 1 having a frame 11 having a vertical direction c and a vertically long direction, and an upper support 11a of the frame 11 including a drive motor.
2 is provided, and by driving the driving unit 12, the traveling roller 13 having a rotation axis in the left-right direction is moved to the transport rail 3
It is adapted to roll on the upper surface of the upper rail portion 3b.
Further, the upper support portion 11b and the intermediate support portion 11c have auxiliary rollers 14, 14, 15,
15, the upper and lower rail portions 3b, 3 of the transport rail 3 are provided.
It is configured to rotatably contact the side surface of c and regulate the movement in the left-right direction. Further, a vertical connecting pillar 11d is interposed between the intermediate supporting portion 11b and the lower supporting portion 11c, and an engaging portion 2h protruding above the hanger means 2 is fixed to the connecting pillar 11d. The degree of freedom allows the engagement. The traveling is controlled by the traveling control device 16 (see FIG. 4).

On the other hand, the load trolley device 4 is also constructed similarly to the power trolley device 5 except that it does not have a drive motor, and the engaging portion 2i projecting above the hanger means 2 is fixed. It can be engaged with a degree of freedom.

A safety net 17 is arranged below the transport rails 3, 3.
