<p><P>PROBLEM TO BE SOLVED: To provide a seal structure by a gasket, which can restrain a fall of the gasket and improve sealability by the gasket. <P>SOLUTION: An abutment surface 11a of a cylinder head 11 as a first part and an abutment surface 12a of an intake manifold 12 as a second part are overlapped with each other through a gasket 25. The intake manifold 12 is provided with a first fitting groove 18, and a first gasket body 26 is fitted therein to seal a gap between the abutment surface 11a of the cylinder head 11 and the abutment surface 12a of the intake manifold 12. A guide groove 23, in which a projection 31 for visual check of the gasket 25 is projected from the first gasket body 26, is formed to be communicated with a first fitting groove 18. The projection 31 for visual check includes a positioning part 33 folded to the intake manifold 12 side, and the intake manifold 12 is provided with guide ribs 35 along both sides of the positioning part 33 for positioning of the positioning part 33. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
