Abstract
A chain adjusting device for vehicles having a rear fork pivoted to a main vehicle frame with an intermediate shaft and a driving shaft rotatably mounted to the rear fork. A primary chain coupling the intermediate shaft with the output shaft of an engine and a secondary chain coupling the intermediate shaft with the driving shaft directs power from the engine to a drive wheel. The intermediate shaft is mounted to the rear fork by means of a bearing assembly mounted to a bracket located between parallel cross members of the rear fork. An adjustment bracket is provided to mount arms associated with the bearing assembly in position.
