Abstract
Plural ignition coils are inserted into corresponding plug holes. Each coil-head of the ignition coil is received by a holder. The coil-head is pressed by a base plate toward the engine. The holder has hooking claws. The base plate has hooking slots to movably engage with the hooking claws, so that relative position between the ignition coils and the plug holes can be adjusted. In case one ignition coil fails, the disabled ignition coil can be replaced individually. A first connector is formed on the coil-head, and a second connector is formed on the holder. The second connector is connected with the first connector when the holder is engaged with the ignition coil at one time. Thus, assembly work process can be reduced.
