PURPOSE:To utilize an unmanned carrier vehicle for a railless and rail induction systems at the time of putting a wheel dedicated for rail system on rail by positioning the lower end surface of the wheel dedicated for rail upper than the lower end surface of the wheel dedicated for railless system in such a way that the wheel dedicated for railless system is floated from the floor surface. CONSTITUTION:A pair of right and left wheels 7 dedicated for railless system, which are driven and run in contact with a floor surface 3, and wheels 8 dedicated for rail system which are run and driven upon a rail 4, are provided on the car body of an unmanned carrier vehicle 1. The height of a pair of right and left rails 4 for rail system, which are laid on the floor surface 3, to the floor surface, is H1. When the wheel 8 dedicated for rail system is put on the rail 4, a condition H1>H2 is satisfied where H2 is the difference in height of the lower end between the wheels 7 and 8, so as to put the lower end surface of the wheel 8 dedicated for rail system upper than the lower end surface of the wheel 7 for railless system, in such a way that the lower end surface of the wheel 7 dedicated for railless system is floated from the floor surface 3 by the height H3. |
