<p>PURPOSE:To suppress vibration during dolly running when object (s) is to be transported by a self-mobile dolly. CONSTITUTION:At the periphery of each rim 1 of a wheel of self-mobile dolly, a plurality of rollers 3 are arranged so that they have rotational axis oriented in the circumferential direction, and the rims 1 are parallel arranged so that the rollers 3 are oriented zigzag. The roller contour is made with a degree of curvature determined by adding previously the deflection amount when load is applied to the roller 3. Thereby the peripheral surface of the rollers when the load is applied can be put identical to the genuine circle outside diameter, which allows suppression of vibration generated by deflection of the wheel.</p> |
