ABSTRACT:
A roller holder for a track steered vehicle consists of functional elements which are detachably joined together, that is to say a head part with a roller height adjustment means, a center part with an annular preferential point of weakness cross section and a connecting part with an arresting means. With its connecting part the roller holder runs on a follower arm for adjustment to track width and the holder is able to be slid along the arm and able to be fixed at any desired position by means of the arresting means within the range of sliding. Furthermore, there is a safety strap in the roller holder which prevents loss of the roller holder if it should break off.
