Abstract: PURPOSE: A cylinder head cover of an engine is provided to prevent a jacket part of an ignition coil from being worn away, thereby continuously supplying stable power to an ignition plug and improving the durability of the ignition coil. CONSTITUTION: A plurality of protruded ribs(5) are formed on vertical walls of ignition coil mounting holes(3) of a cylinder head cover(1), guiding a jacket part of an ignition coil. The plurality of protruded ribs are formed in a vertical direction at regular gaps to prevent the jacket part of the ignition coil from eccentrically mounting on the vertical walls of the ignition coil mounting holes. Therefore, if a worker fixes a fixed hole at a boss part of the cylinder head cover by screws, the jacket part of the ignition coil is mounted on the vertical walls of the ignition coil mounting holes, without being eccentric automatically.
