PURPOSE:To miniaturize a motor-driven runner and increase driving forces for the runner by integrating a runner body having plural driving rollers, the driving portion of the main body, an electricity collecting mechanism and a partition hanging into one structure. CONSTITUTION:Six driving rollers 12 each having a gear 12c provided on the back face thereof are axially attached to both sides of a runner main body 11. The main body 11 is provided with a hollow hanging bolt 13 and a sleeve 13c which is threadbly engaged in the bolt 13, to hang a partition panel P. A transmission shaft 14 is passed through the hanging bolt 13 and is connected at its lower end to the extension shaft 15 of a motor and all the rollers 12 can be driven by a gear mechanism. Further the main body 11 is provided with a blush 17 and a guide roller 18 to form a motor-driven runner 10. The runner 10 is disposed in front of and behind the upper edge of the panel P and electricity is collected from a trolly wire TW so that the runner 10 travels on a hunger rail HR. The runner can thus be miniaturized and also made strong enough to stably travel. |
