PURPOSE: A head cover sealing structure is provided to reduce assembly procedures, parts count and costs by eliminating the necessity of using a washer. CONSTITUTION: A bush(20) is press fit into the hole formed at a head cover(10), and a bolt penetrating through the bush is coupled to a cylinder head to thereby mount the head cover on the cylinder head. A gasket(41) is mounted at the outer portion of the surface of the head cover. An indenting hole(11) is formed by expanding the top of the hole formed at the head cover, and an O-ring(70) is press fit into the indenting hole. The head cover is mounted on the cylinder head by a flange bolt(31) penetrating through the O-ring and the bush.
