Abstract
A shaft having a sprocket fixed at one end thereof is reliably assembled to the supporting wall of an engine, with a reduced number of parts and man-hours required for assembly. A camshaft having a sprocket fixed at one end thereof is installed by engaging a pair of ball bearings with supporting holes on supporting walls of the engine. A crescent-shaped step partially cut in the loosing direction of an endless chain is formed on one supporting hole. An outer race of one ball bearing on the camshaft is engaged with the step. An endless chain is wound around the sprocket, and the one ball bearing is moved into the supporting hole, and the other ball bearing is correctly engaged with the other supporting hole, thereby completing assembly of the camshaft.
