。 The packing that is press-fitted between the fuel injection nozzle and the cylinder head is molded from a soft metal with excellent thermal conductivity, and a thick tightening part is formed at a position spaced from the combustion chamber side of the nozzle. In addition, the injection nozzle packing is formed with a thin cooling part which radiates heat from the nozzle to the combustion chamber side from the tightening part to the head side.
