<p>The roller has an electrically conductive wire (60) with an end (61) set on an end (58) of a rivet shank (54) of a rivet (52), and another end (62) that is in contact with a rotating shaft (12). The latter end of the wire is housed in a groove (66) realized in a bearing (16). The groove comprises depth equal to thickness of the latter end of the wire. A pivot (40), shaft and a wheel (10) are made of electrically conductive materials. Length of an plug end fitting (42) of the pivot is determined such that an end (49) of the fitting located in a blind hole (30) is in contact with the shank.</p> |
