Abstract
A sleeve structure comprises a plurality of sleeve main bodies fitted respectively into intake ports of a cylinder head of a multi-cylinder internal combustion engine and a shared base provided on one end of the plurality of sleeve main bodies. By fixing this sleeve structure to the cylinder head, an amount of labor involved in a fixing operation for fixing sleeves to a cylinder head is reduced.
