Abstract
There are described a height adjusting device for an extendable screed plate for a road finisher and a road finisher comprising such a device. A ground element of the extendable screed plate is disposed with two pairs of worm gears on a top part of the extendable screed plate for vertical displacement thereon, wherein the worm gears of each pair are interconnected by a power transmission for concomitant actuation. Each pair is provided with a releasable clutch, preferably a conical clutch, by means of which the connection between an adjusting member of a pair and the associated transmission gear can be broken.
