PURPOSE: To supply power or signals of a trolley wire in a rail into a panel securely and stably by a collector ring of a travel device provided in each panel. CONSTITUTION: A collector 28 is formed at least into two branches, and respective collector rings 24, 24' provided at a tip of both branches are apart from each other in the front and rear of travel direction by the length by which they are across an insulating material 19 of a connection section 18 of at least unit trolley wires 3 and a clearance of rails 2. For this reason, even when the collector 28 passes the insulating material 19 and a clearance of the rails 2, at least either of the collector rings 24 (24') is positioned on the unit trolley wire 3. Consequently, it is possible to receive power and signals from one collector 28 securely. |
