CONSTITUTION:The wall surface of an intermediate portion between adjoining boss portions 18 of an intake-manifold mounting portion 9a is inwardly curved from the flange side wall surface of a cylinder head 6 to thereby provide a concave portion 23. The intake manifold is thinned in conformity with this recessed portion 23.</p> |
