Abstract: PROBLEM TO BE SOLVED: To provide the ignition coil device fitting structure allowing easy fitting of an ignition coil device at a low cost. SOLUTION: A core 21 exposed out of a coil case 11 of an ignition coil device 10 is formed with a through-hole at a part near a high pressure tower. A bolt 40 is inserted into this through-hole so as to fasten the core 21 to a fitting seat 2. A case projection part 30 has a resin projection main body 31 integrally formed with the coil case 11 and a rubber cap 32 as a rubber member fitted in an engine side end of the projection main body 31. The rubber cap 32 is pushed to a surface 1a of an engine head cover 1 with a large force by fastening the core 21 to the fitting seat 2 with the bolt 40, and the large friction force generates between the rubber cap 32 and the engine head cover 1. Furthermore, even if the rotating force is applied to the ignition coil device 10 in the same direction with the rotating direction of the bolt 40 when fastening the bolt 40, a rotation regulating projection part 3 locks the case projection part 30.
