ABSTRACT:
A camshaft has contrarotating cams for automotive engines, in which an inside shaft and an outside shaft are arranged concentrically so they are contrarotating, at least one cam has at least one main cam element that can be placed radially on the outside shaft and is supported there so it can rotate. The main cam element is connected to the inside shaft in a manner that is rotationally locked via a fastener passing through a recess in the outside shaft. Further features include a fastener, a main cam element and a locking means. The fastening of the main cam element to the inside shaft is provided by widening the outside diameter of the fastener by the locking means with a resulting tightly seated connection between the fastener and the inside shaft, and the fastener and the locking means.
