A joined prefabricated individual cam includes multiple cams for an adjustable camshaft in particular for an internal combustion engine of a motor vehicle. The camshaft has two shafts mounted concentrically one inside the other, namely an inner shaft and an outer shaft. The joined multiple cam is fixedly pinned to the inner shaft via radial openings provided in the outer shaft with a rotatable bearing on the outer shaft. Such a multiple cam has at least one prefabricated individual cam which is placed as a cam ring on the outside circumference of a carrier pipe at an axial distance from the neighboring individual cams and is fixedly connected to this carrier pipe at a predetermined angle of rotation and axial distance assignment.

An anti-rotationally secured tappet of a valve drive of an internal combustion engine may include a bucket tappet including an external lateral surface. A floor and a skirt for may be arranged between a cam and a valve of the valve drive and guided in a receiving bore of a cylinder head. The skirt may include an internal lateral surface and the cylinder head may include a guide groove. A radially outward protruding anti-rotation component may be arranged in a recess of the skirt that glides in the guide groove of the cylinder head. Two spring arms may be included with the anti-rotation component and extend in a circumferential direction of the tappet.
