Abstract: PROBLEM TO BE SOLVED: To improve assemblage at low cost when an intake muffler is fixed by push-pressing tip ends of projection parts after projection parts of a cylinder head are inserted into holes of a steel belt, and caulking the steel belt. SOLUTION: Two projection parts 5a formed integrally with a cylinder head 5 are arranged holding an inserting hole 10, holes 6a whose diameter is smaller than that of a projection part 5a are arranged on a steel belt 6 having a spring performance, and are arranged so as to insert around the projection parts 5a. After projection parts 5a of the cylinder head 5 are inserted into the holes 6a of the steel belt 6, tip ends of the projection parts 5a are push-pressed, and thereby, the steel belt 6 is caulked, a communicating pipe 4a is brought into pressure-contact with the inserting hole 10 by the spring performance of the steel belt 6, and thereby, an intake muffler 4 is surely fixed to the cylinder head 5. Since the cylinder head 5 is formed integrally with the projection parts 5a by aluminum die-cast, the number of part items are reduced.  It is thus possible to reduce a cost and improve workability by reducing the number of the part items.
