Abstract
A cam lobe is formed as a single part, not formed together with a shaft body. The shaft body penetrates through bearing holes, as well as a mounting hole provided in the cam lobe, which is arranged in between adjacent bearing holes. The bearing holes each in a perfect circular shape can be achieved, since there is no need to divide the bearing holes into two semi-circular arc shaped concave portions. Consequently, a camshaft can be supported so as to rotate smoothly.
