Abstract
Abstract A camshaft has a cam arrangement with a projection and recess coupling the camshaft with a cam member which permits limited relative angular motion between them. The cam arrangement includes a hollow cylinder affixed to the shaft with a projection received in a recess in the cam member. The cam member and the hollow cylinder are held together by rings at their end faces into a pre-assembled unit which is slid on and affixed to the camshaft.
