摘要： To facilitate mounting of each ignition coil into each coil mounting hole formed in each cylinder head accurately with respect to both the longitudinal and angular positions of each ignition coil, a cylinder head is formed with a coil mounting hole including a first large-diameter inclined coil mounting hole, a second small-diameter inclined coil mounting hole, and an intermediate partially conical surface for connecting the first and second inclined coil mounting holes in axially eccentric positional relationship with respect to each other; and an ignition coil formed with an outer casing so as to be inserted into the coil mounting hole formed in the cylinder head. Further, a rocker cover sealing member is disposed along each of junction circumferences of two coil mounting holes and between the cylinder head and the rocker cover to prevent lubricant from flowing from a cam chamber to the ignition coil casings and further to the ignition plugs.
