Abstract: A valve train of an internal combustion engine has rocker arms which are spherically supported on lash adjusters and camshafts disposed above the rocker arms. The camshafts are rotatably supported on a cam holder including a lower cam holder which is fastened to a cylinder head and an upper cam holder. Projections for preventing the fall of the rocker arms in axial directions of the camshafts through the contact with the rocker arms are provided on bearing portions and partitioning portions which are integrally formed on the lower cam holder in such a manner as to face both sides in the axial direction of the rocker arms.
