As shown in FIGS. 1 to 4, the rail R is arranged with upper and lower angle pipes 3 and 4 having a substantially square cross section extending in the traveling direction with a predetermined vertical interval, and the upper and lower angle pipes 3 and 4 are arranged at a predetermined interval. Are connected to each other by a number of connecting members 5 arranged to extend in the traveling direction, and the angle steel 6 that opens laterally on one side of the rail R is formed in the longitudinal direction of the rail R. A rack 7 having teeth protruding downward on the lower surface of the angle steel 6 is fixed by extending in the longitudinal direction of the rail R, and three conductors are provided on the other side of the upper square pipe 3. The power supply rail 8 made up of is extended in the longitudinal direction.
[0014]
As shown in FIG. 1, the vehicle body 1 has an upper surface, left and right side surfaces, and a lower corner pipe of the upper corner pipe 3 at the front and rear portions of a substantially rectangular frame-shaped body frame 9 that surrounds the upper and left and right sides of the rail R. The left and right side surfaces 4 are provided with front and rear traveling portions 11 and 12 having five rolling wheels 10 that roll, respectively, so that the vehicle body frame 9 can travel on the rail R.
[0015]
A cabin 13 for carrying personnel is mounted above the body frame 9, and the cabin 13 directly supports the lower surface of the front portion of the floor plate 14 of the cabin 13 at the upper end portion of the front traveling portion 11. The rear lower surface of the floor plate 14 is supported by the upper part of the rear traveling unit 12 via the support column 15 to maintain the horizontal state of the cabin 13 so that it can cope with various inclined rails R by replacing the support column 15. Yes.
[0016]
As shown in FIGS. 1 to 4, the traveling drive unit 2 is coupled to the rear traveling unit 12 via a coupling unit B, and a gear box 20 is disposed on one side of the rear portion of the vehicle body frame 9 to A pinion 22 meshed with the rack 7 is fitted to the inner end of the drive shaft 21 inserted through the box 20 in the left-right direction, and a motor 23 is interlocked and connected to the upper surface of the gear box 20, and the power supply rail is connected to the motor 23. Electric power is supplied from 8 to drive the monorail car A to travel.
[0017]
As shown in FIGS. 1 to 4, the connecting portion B has a bracket 24 protruding from one side of the rear portion of the body frame 9, and a base end portion of a connecting rod 25 extending rearward on the lower surface of the bracket 24. It is fixed with two bolts 26 and 26, and a bolt 27 is inserted vertically into the rear end of the connecting rod 25 and fixed with a nut 28.
