Abstract
Intake and exhaust cam shafts are disposed a cylinder head in a vertical direction. The cylinder head comprises a first through hole and a second through hole. The first through hole penetrates an upper surface deck from a deck surface towards a lower surface of the cylinder head. The deck surface is a surface constituting an upper surface deck of the cylinder head. The second through hole opens to a side surface of the cylinder head in which cam pulleys of intake and exhaust cam shafts are provided. The second through hole penetrates the upper surface deck along an axial direction of the intake and exhaust cam shafts. The second through hole is positioned vertically below an opening in the deck surface of the first through hole.
