<p><P>PROBLEM TO BE SOLVED: To provide an unmanned conveying truck, comprising three traveling wheels of a basic constitution that the most stable three-point support mechanism is applied, in which it is made to a traveling wheel unit in which the three traveling wheels can be exactly ground-contacted at good balance regardless of existence of recession/projection of a floor panel (grating) for forming a traveling passage of the traveling wheel for the unmanned conveying truck, a traveling wheel assembling mechanism is established by a hierarchical mechanism of three-point support of the traveling wheel unit and approximately uniform load is applied to all traveling wheels. <P>SOLUTION: Three traveling wheels 3x constitute one unit 3a-3d and in the respective units 3a-3d, the traveling wheel support member 33 is provided with the traveling wheel assembling mechanism pivotably connected in all directions relative to a mounting member at a predetermined position of the respective units 3a-3d. The respective traveling wheel units 3a-3d are supported to a bottom surface part of a floor surface member on a frame of the unmanned conveying truck by the hierarchical mechanism of three-point support. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
