UNMANNED CONVEYING VEHICLE AND CONVEYING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a traveling mechanism and a traveling wheel mechanism not to damage a floor panel of a clean room of an unmanned conveying truck ready for an increase in the size of a substrate and an increase in the loading capacity.

SOLUTION: A steering mechanism and traveling wheels at two rows having a driving mechanism are provided on an unmanned conveying vehicle. The pitch between the traveling wheels of the unmanned conveying vehicle is set to be larger or smaller than the dimension of a floor panel member of a single shape, and the position of each traveling wheel abutted on the floor panel member is different from each other for each traveling wheel to mitigate irregularities formed attributable to the deflection of a floor surface.
