An engine has a first camshaft having a power input portion at one end thereof and a second camshaft interlocked and connected with the first camshaft at one end portion thereof have axes which are parallel with each other and are rotatably supported on a cylinder head and in which a driven gear meshing with a drive gear provided at the other end portion of one of the first and second camshafts is provided on an auxiliary device drive shaft connecting to an auxiliary device mounted on an engine main body including the cylinder head, wherein an axis of the auxiliary device drive shaft is disposed between the first and second camshafts at a position closer to the cylinder head than a straight line connecting the axes of the two camshafts.

Engine

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.
